43rd Week: 10/11/2016

Started painting about 30% finished 95% metal work done 95% 3d printing done designing of expansion modules progress 75% should be sending out the surveys after paint is finished another support request finished. Please get ahold of me to send in your electronics to repair the issues. ordered last batch of power supplies and I might need to make a order to get replacement band heaters as some of them have issues with their thermocouples.

42nd Week: 10/4/2016

About 90% printing done About 90% of steel work done only thing left is painting. 50% done designing the expansion modules survey for international backers to come out after painting units(about 1-2 weeks) Another Support request fulfilled. please get a hold of me to get information on how to send me your electronics for repair. Thanks.

41st Week: 9/27/2016

about 80% done with all welding. had issue last weekend because i ran out of argon and co2 mix so couldnt finish welding about 80% done with 3d printing just need to do all the drilling then final welding and we are ready for paint. still designing all the expansion modules those will be done soon. also sent out a emails to all the people that i have support tickets for. that it would be best to send your electronics to me so i ca fix them and check that they work before i send them back. please look for those emails and respond. i also found out that i might have a issue with needing more heater bands so also need to sort that out.

40th Week: 9/20/2016

Back into the groove after the start of school i am about 60% done with international unit assembly finished my 2nd support ticket and i am going to be working on support tickets every Friday and every most days of the weekend after 100% assembly on international units i have started to design the expansions modules. i already have designed the dimensional control rollers. on schedule for shipping of international units at the end of next month. still waiting on ordering the power supplies should be ordered by the end of this week. everything is on schedule for international orders and working on fixing the support requests.

39th Week: 9/13/2016

Finally i have got my school under control and have added all of my classes on the last day to add yesterday. So now i finally will be back to full time on weekends Friday - Sunday got the 7th survey for second batch and am working on sending that one out I have checked out my stock of extra parts i made in last batch. i have the main mounting plates, motor mounts, and 1/4 inch back plates already made in last batch. So i am already more than half way done with international units from left over parts from last batch. I have also started to design the dimensional control unit and spooler. I now need more power supplies and to figure out the issue with the screens as it seems that the supplier no longer carries the ones that i sent out last 2 batches. should be done with all the steel and stuff for international by the end of the month and be done with most of the designing of the modules by the end of the month and have them made and ready to ship out my the end of october.

38th Week: 9/6/2016

Finally got some new filament in. So i have begun printing bottom plates and top covers. also just found out that one of my suppliers sent me different tft touch screens that require slight modifications in the software when i told them to give me the same ones. so i have to wait for those to come in. i have also built the units for people outside the kickstarter and i will be painting them this weekend. One of my early bird backers has sent me there broken electronics and that seems to speed things up. i will see how that goes and if that is quite a bit better option to just send in the broken parts. first week of school has been pretty chaotic adding classes and all i should be getting back in the grove this weekend. focus is going to be fixing broken units and building international units

37th Week: 8/30/2016

All second batch has shipped i have started to work on support on the first batch. if you have not received a email about a support ticket created for you or that you havent created a support ticket yet than please let me know about the damage on your unit. I have 6 more support tickets left to fulfill. please make sure to answer any questions i have asked on the support ticket and that i know about all the damage i am back in school so i will be back to part time i will build the units ordered outside kickstarter this weekend. International units will be done in a month or so and the modules will be developed after that. should have international units out in 2 months.

36th Week: 8/23/2016

5 out of the 6 units of the second batch have been sent out. the remaining one will be sent Wednesday or Thursday. Printing of replacement parts/ international backers to begin Thursday onward I will be working on replacement parts before I begin making international backers units 1 person in the second batch has still not submitted his/her survey please do so. I start school Thursday so I will be back to part time. First video of my research series on my YouTube is coming very soon (Thursday/Friday). it is talking about moisture in filaments effect on 3d printing. check out my research blog to get a glimpse before the video is made. Check bellow for pictures.

35th Week: 8/16/2016

Everything is done and i have decided on how to handle the shipping for this week i have shipped one unit using the new corn starch packing pellets out to to south California ( coming to you Andrew i will get in touch with you soon). When that unit gets there without damage i am going to send one out further to South Carolina (to you Stan). If that one also arrives without damage i am going to send the rest of the batch I am going to start printing the replacement parts for the people that need new electronics kits or welded couplers. STILL 1 PERSON THAT HASN'T FINISHED SURVEY PLEASE DO SO also make sure that if you have any damage make sure that i know exactly what needs to be replaced and i will be picking up boxes to ship replacement parts soon. Development on the expansion modules will begin while i am sending out the replacement parts to domestic backers. also the after kick starter units will be sent out. i go back to school august 24th (1 week) i will be going back to part time to finish development and building of international backers units by the 24th of next month (hopefully) and hopefully i am done with the expansion modules to send them packing internationally.  also check out my new series on youtube and my website/blog for 3d printing research.  check out pictures below

34th Week: 8/9/2016

On to Electronics. Everything else is finished. So just electronics testing then shipping. Ordered my new packaging materials. Corn Starch packing peanuts. i have ordered 12 cubic feet.  so that should be my main packing material along with wall plastics which are still cutting mats and i am trying to price pla sheets but that is not fleshing out. still on time that one person that has not responded to the survey for second batch please respond asap. thanks printing will begin for the people whose electronics broke. and now i have packing material for it with peanuts. you will also get the new version of the cover and the fan shroud. if anything else broke in addition to the electronics and plastic that i dont know about please let me know. i am still on time for shipping everything out by end of next week and mabye some at the end of this week. for people that ordered units after kickstarter your units will be painted after shipment of batch 2 finishes. international i will begin working on the expansions and building your units asap.

33rd Week: 8/2/2016

about 90% done with the welding still about 80% done with printing as the techshop makerbot is having some issues need to find the funds to fund a large enough format printer of my own 90% done with the drilling painting is going to start this week i will have to probably make a order of temp sensors, power supplies and a few other things that i need. i will be printing the covers and plates for new electronics packages for the people whose electronics broke after the 7th unit in second then i will be printing the outside orders which there is like 3-4 still on time for 80% of units out by 2 weeks from now for second batch.  IMPORTANT: i notice that one of my 2nd batch backers hasn't responded to the survey please respond. thanks.

32nd Week: 7/26/2016

Welding has started. 80% of drilling has been finished and 100% of steel cutting has finished 70% of 3d printing has finished this week printing of the electronics mounting plate has finished and i will start printing the modified covers  this week i also plan to start painting i will be doing something different this batch. i will start shipping out the units as i finish making them. When they are finished and ready to go i will ship them out. that way hopefully if any more issues arise with usps i can spot those issues and mitigate them before i ship any other units. people that purchased a unit after the kickstarter your units will be painted after the kickstarters backers units go out. sound be around 1-2 weeks after kicksarter backers units ship people that got damage units in last batch i will most likely be preparing a new electronics kit and plastics for you guys to bolt onto your unit if anything else is missing please let me know. Also if you are looking for arduino uno clones i have them up on my ebay check them out here 11$ for 2 free shipping http://www.ebay.com/itm/2-Arduino-Uno-SMD-CLONE-U-S-Based-Shipping-/322186110850?rd=1 estimated shipping date of batch 2 is 2 weeks from now

31st Week: 7/19/2016

Finished cutting all steel needed. For next batch. drilled all necessary holes on 1/8 inch main plate released version of 1.1 of the MOS (Multistruder Operating System). check out details on my multistruder dev blog. new version is posted on my github. started writing the plans to make a multistruder yourself. you can check it out at link bellow. started posting to multistruder dev blog again and i am going to talk about when anything else is added to the multistruder there. check it out. stated a github to hold all my software (for now) as well as the 3d printed parts stl https://github.com/TheGreenEngineersCompany/MOS posted the survey for the second batch backers. 5 of 7 have responded please march backers check your survey and get that in asap. people that ordered units for domestic shipping will get there unit after i ship out this next batch of 7. they will be made at the same time just packed and shipped after i insure that all the domestic backers are shipped out. i have still not heard back from anyone that had a broken unit please get back to me so we can move forward to repairing your unit. I am talking to usps about insurance. whether or not that goes through i want to send you the parts that are broken. please watch the electronic and assembly video and tell me what you are missing and what is broken.  just shipped out mikes unit. so now all 13 from the first batch are shipped out. In mikes i put alot of padding in we will see how it fairs in shipping and adjust the packaging accordingly on future shipments. again i will be delayed by printing of the large plastics. eta on finishing all metal work end of july. and shipping out early august. website units will be shipped out early to mid august.   Packaging that i am experimenting with is the "spring pad" biodegradable/Compostable cardboard pad. you can see bellow. also the honey comb shaped "bubble wrap" replacement also biodegradable/compostable honey comb recycled paper. biodegradable/compostable and renewable packing tape. all from ecoenclose. i am also experimenting with lining the sides of the box with "cutting mats" cut to size in order to keep the sharp steel from going though the side of the box.

Batch 2 Survey Posted

Kickstarter batch 2 survey posted. I have started building the units for batch 2 and the units for the domestic orders placed on my site after the kickstarter. please finish the survey as quick as you can. we are looking at late July early august for kickstarter backers and early August to mid August for domestic orders placed on my site after the kickstarter. Again thanks for your patience .

30th Week: 7/12/2016

started a github to host all of the files for the MOS system and 3d printed files. I am currently updating all of the files and new versions will be coming every week. check it out here https://github.com/TheGreenEngineersCompany. fixed my kossel at home so i will be printing at home aswell. i have started printing the new versions of the fan duct to send out to the people whose broke and for new backers. i am going to try to start assembling the units at home. as i mainly weld at home and i do have all the equipment needed so it will just be easier. i have bought some bubble rap (a little late i know) however it is super thin it will take at least 6-10 sheets per unit to pack the boxes. so i am going to start looking into a packing material from eco enclose. which looks like a cardboard bubble rap replacement and it comes in 1/4, 1/2, (and i guess 3/4 and 1 inch) thick. it looks very promising because of how padded it looks. It is also all 100% recycled and compostable material. i have a sample piece coming in tomorrow as well as some plant based tape. aswell as some boxes as mentioned in past point i have purchased some boxes to sell the arduino unos, mechanical relays, and max31855 3.3v version op amps that i am not going to use. i am going to post them on ebay and amazon if you guys are looking for some arduino unos and other electronics i might put them on my store for a killer deal let me know.   On another note for those that have issues with parts being broken i reached out to those that have reported issues (if I have not please let me know) please get back to me about what is exactly broken asap and i will work twords replacing all that is broken. also for other people that have gotten units that were not critically damage have you guys put them together? do you need any other information to put them together other than on my youtube which you can find here https://www.youtube.com/channel/UCr-qLNzQib4fZ92AzqlIusA . please keep me in the loop of anything else you need while i push forward in making the next set of orders, keep developing the extruder, and develop the expansion modules.  i will try to get a new version of the MOS system every week (probably released on weekend on github). However i need to get mikes machine out and i will have to build the rest of a unfinished machine i have sitting in the garage. so be looking out for more stable versions of the MOS coming out weekly to improve the quality of MOS extrusion and user experience. Thanks again for backers for your patience and i am again sorry for the broken machines. mike i will be contacting you shortly. check out pictures bellow. and i will post that packing material that i get tomorrow.

29th Week: 7/5/2016

First batch has been shipped out the only one needing to be shipped is mikes. There have been reports of critical damage to 3 out of 12 units. People that have critical damage to there unit I will be getting to you shortly to replace what is broken. There are also some people that have reported some chipping of the paint. please let me know the severity of the issue and I will see what I can to fix it. However everyone please be very careful with the paint as it scratches easily. eventually I want the units to be powder coated with pla colored in the Multistruder. I will be back home Thursday to continue work on the project. I'm going to start working on the next batch and working on reinforcing the flat rate shipping box. and finding suitable padding that will keep the contents as safe as possible from the stuff moving around the inside and protecting the box from the outside. While on vacation in Oregon I had the opportunity to meet up with some of the great guys at proto plant in Vancouver Washington. The makers of the Proto-Pasta brand. We spent some time shooting the shit talking about filament making and diy filament extruders. I brought back some important wisdom from the meeting. the number 1 thing being to DRY YOUR STOCK BEFORE EXTRUDING. I had a issue of the filament that was made being very brittle and not able to flex without breaking. This was because of the high content of moisture of .21% (should be .030%) and this moisture was found in a Ziploc pellet bag that I never even opened. and 2 being that the longer you have the plastic heated before extrusion the more brittle the plastic becomes. They had a similar setup to what I envisioned for the multistruder. except their setup is a lot longer run out to allow the filament to cool before getting to the sizing drums for a 1 1/2 foot per second extrusion rate (90 feet per minute 30 times the extrusion rate of the multistruder). They used drums with force sensor to size the filament and drums to pull the filament to size and spoolers that keep up with the pulling drums. assembly, electrical , and extrusion tips and tricks videos are posted on my youtube channel. The Green Engineers Youtube bellow you can check out some picture of stuff thought the week

Early Bird Batch Shipped 6/30/2016

Multistruder kickstarter Early Bird Batch Shipped 6/30/2016. 12 units have been dropped off today at 3:30 at USPS and should be arriving at most locations 7/2/2016 and some at 7/3/2016. Any questions you have now or when your receive your shipment please contact me.  the 13th unit (unit number 1 also the unit you have seen in the extrusion tips video) it requires some more work but will be shipped at the start of next week either Tuesday or Wednesday. Sorry Mike Langford but your unit will be loaded with the the newest updated software that i develop over the weekend while i am on vacation in Oregon. if you have any questions Mike please get contact me. For people that are on the next batch 2 the survey will be out to you guys pretty soon and as of now i am working on batch number 2. Again thank you backers for your patience. extrusion tips video is on my youtube and assembly video is coming soon.

28th Week: 6/28/2016

i currently have 10 units in boxes waiting for labels. just 3 more units left. box are shceduled for late thursday pickup. All early bird backers check your address to make sure it is up to date. boxes come in at about 16 pounds Going to be making a assembly video aswell as extrusion tips for the standard die (because no one asked for aggressive die) tommarow. i have found that the analog thermocouples are not very exact out of the box so they are going to need to be calibrated. thus next week i plan on making adjustments in the code to allow for the calibration. calibration will probably be handled using ice water. also please subscribe to my youtube channel for more videos thanks. any pictures will be posted bellow.

27th Week: 6/21/2016

today marks the start of the 27th week of fulfillment. wrapping up first shipment getting all the necessary things as i plan on having everything in its box and postage printed.  However i have the last choice for backers here. I have discovered 2 options as far as DIE types 1 being Standard style and 2 being Advanced/Aggressive style. I will outline them below. Standard die is a style that alot of other filament makers use. This is found by using the perfect extrusion temperature for a given height above the floor where the filament expansion and stretch are equal. This means that you have a hole that is drilled that is exactly the same size as the filament you want to make. So if you want 1.75 the die hole is 1.75. Pros: filament is extruded at a lower temperature and thus you have less of a chance to have issues with the filament breaking because of excessive heat. From my testing it doesn't even need a cooling fan in most situations. filament tends to make a larger loop and this allows filament from last loop to cool down before next loop laps over the last loop. Because we are dealing with 3d printer filament thermoplastics that are designed to stick to itself when hot you want your filament to cool to keep the filament from sticking together rather than becoming just a large molten mess. Cons: extrusion is slightly slower because of lower flow rate you are looking at 3 feet or less extrusion rate which is still faster than pretty much all 3d printers anyways and other extrusion makers. Advanced/Aggressive (now going to be called Aggressive) this is a die that is drilled (about .2mm) over size for your filament to allow for stretching to size and to maximum extrusion speed of 3+ feet per minute. However this die has a lot of cons and only one real pro and that is extrusion speed. Thus this die is for the dedicated moders. Pros: Extrusion speed 3 feet + Cons: Filament has a higher chance of stretching and breaking. So a lot of moding to keep the filament from breaking and special placement of the cooling fan and calibration of extrusion heat. Filament will try to shape to the over size hole like the standard die. so if you have a 1.95 aggresive die to stretch to 1.75 filament will try to shape to 1.95 if your settings are off. Filament will create tight about 1 inch loops that will do a loop in about 5 seconds or less this is before filament has chance to cool thus unless you make really good use of the cooling fan/ other fans the filament will fuse to each other and become a solid chunk of plastic and be inseparable into filament loops. (pretty much useless unless you remelt) Filament is really tight in 1 inch loops that will be very difficult to put on a spool and will try to snap if you try to flex it to much Might be more cons but this is all i know as of now From the above statements i have chosen to have the Standard Die as well the standard (it being a more dependable option). however the Aggressive die is available as i have the bits for both styles for both 1.75 and 3.00mm. that being said i will assume that you want a standard die and not the advanced IF YOU DO WANT AGGRESSIVE GET IN TOUCH WITH ME OVER KICKSTARTER. send me a private message using the same account you backed with and i will put that perticular die in your kit and if you dont send me a message i will just assume you want standard and put that one in your kit. IF YOU WANT TO SWITCH DIES THAT OPTION WILL ALSO BE AVAILABLE ON MY STORE AT A LATER DATE (also a get another die to switch between 1.75 or 3.00mm) PLEASE ONLY EARLY BIRD BACKERS SEND ME A MESSAGE the other backers will have this added to your survey when it is sent out. Other news being that i have modified a few things to make them work. one being the fan shrouds. I also figured out how i am going to do shipments etc. also ALL UNITS HAVE BEEN TESTED AND WORK so i am very excited to rap up this first batch. i have also noticed that the analog thermocouple amplifiers will need some calibrating but are more reliable than the digital amps and are less susceptible to noise which i found is a huge problem for the digital amps. So i will be adding some calibration stuff into the software for the temp. You will probably have to use a cup of ice water and boiling water to calibrate. Few more things need to be cleaned up before batch one goes out then next batch starts as well as continual support of all machines that get sent out to early birds.  So to all early bird backers that want the Aggressive die please send me a message on kickstarter before friday the 24th. and check out pics bellow and more vids coming soon on youtube.

26th Week: 6/14/2016

Today marks the 26th week of kickstarter fulfillment. have all units built and have now checking them to make sure that all the electronics work.  i have received the analog thermocouple amps a day after last weeks post. they are working great however they dont really seem to be calibrated that great even with cold junction compensation. i will need to be able to remedy that or just add a offset in the interface were you calibrate it to your ambient room temp or icewater etc. i have done more filament making and it brings up other questions. I found 2 different ways of extruding one is when you get the temperature just right and the filament matches the size of the die and it makes LARGE circles as it extrudes and thus 95% of the filament is +- 0.10mm of the die size.  the second way is to oversize the die and heat the filament to the point where it stretches as it comes out. this will cause the filament to stretch to size and create SMALL circles as it coils on table/floor. however in practice this seems flawed as the filament is so hot that it sticks to the previous loop of filament bonding it together. while the previous method would cause the filament to be cooled enough to were it wouldn't bond to the previous loop. this extrusion type is also +- 0.10mm of desired size however the filament will try to return to the die size so you will see the filament more + than - your desired filament size. i will do one more week of testing and should be ready to drill and send out units by end of this fulfillment week. check out pictures bellow. also i have more videos to come of the multistruder extruding plastic i will be posting them on my youtube and embedding them at the beginning of this entry when i post them.

25th Week: 6/7/2016

today is the start of the 25th week of fulfillment Just got in the Arduino Megas all 13 have been swapped out for the unos that have been currently built. all 13 are assembled and now just need to be wired. I am still waiting for the analog themocouple amplifiers. Ran the extruder again and this time got conflicting results to before. now i am getting the same size extrusion as the hole drilled (2.00mm) +- .10mm or so. This would would mean that the amount the filament expands and stretches is the same and leaves you with the same size filament as the hole that is drilled. Further experimentation is needed before i drill the holes. However from the last run i have got some gorgeous footage of the extruder going about 3 feet per minute (doing a 1 inch diameter loop in 5 seconds) with good 2.00mm filament. video should be posted down bellow then posted on youtube later. I unfortunately had a accident in the shop while cutting off the cutting edge of the feed augers to be a constant screw. I sustained a large cut on my index finger on my right hand (right handed). The auger was ripped out of my hand by the saw i was using and the end cut me as it was ripped out of my hand. I had to go to the ER and get 5 stitches. So took that day off and have been slowly getting back working and such since the incident saturday. As i was not really able to use my right hand which is my dominant hand. Sunday i showed The Multistruder project at the San Jose Tech Shop open house and got a lot of praise for the design by other members, faculty, and other attendees Waiting on the thermocouples to come in before final testing begins then the units can be dissembled and thrown into a box and shipped out. Then the other work begins on a youtube/documentation series on how to assemble them as well as best practices and hopefully weekly updates on the software ("MOS") as it right now is just a stable version with BASIC functionality. check out pics and extruder video bellow. and i will add a picture of my finger last if you are squeamish skip that one (no blood just the stitches).

24th Week: 5/31/2016

today marks the start of the 24th week of fulfillment. ran the new extruder for the first time. Learning how the extruder wants to be setup and as assumed when you are extruding the filament you want to SOFTEN the plastic not MELT it.Thus you are shaping it at its softening temperature by pushing it through a die. if you melt the plastic the diameter becomes almost impossible to control. However if you soften the filament will contour to the die hole as it comes out and will expand as it is really hot. It will also stretch a little but not considerably before it cools to a pliable state. While in the pliable and still soft state this is when the filament must be shaped to be put onto a spool or when it coils itself up on the floor. Knowing this now you will probably not need the fan that much as it will harden to quickly and hold the shape of a straight line before it has a chance to coil and hold the coil shape as it cools back down to room temperature. The die i was using was drilled to about 2 mm and i was getting 2.5-2.6 mm filament when softening and .75 to 1.25mm when i was melting the filament. so that is a .6mm size expansion when softening. i am going to continue to study how undersized i should go in order to get perfect 3.0mm filament and 1.75mm filament. I should have the desired drill sizes by the end of this week.  after going though quite a bit of practice plastic from the above dimensions the extrusion was mainly 85% -.125 average case (it really didnt expand past 2.6). this is pretty good for only using the extruder for 2 days. I now know that going with a 2 amp only power supply to a motor that can take 10 amps was a really good decision. The 2 amp to the motor causes it to stall ALOT of the time but it will only stall if one of these conditions are wrong 1. being you filled the hopper up to much 2. temp too low 3. temp too high. Bellow i put at story of what could happen if a larger power supply was used. In order to try high amp no control performance i put on a 10 amp power supply as it was stalling alot and condition number 3 of the temp being too high was present. What i could guess happened was 1 of 2 things either the heat spread up the pipe and melted the plastic to the auger and to the side wall of the pipe and this basically "gummed" the auger up to the pipe by melted plastic. 2. the molten plastic bellow was basically a liquid and as you push solid pellets in there is pressure buildup but no extrusion because it is a liquid and not a semi solid. the molten plastic would also insulate the pellets inside and the pressure built up as nothing was able to extrude. whichever of these 2 causes (im 80% positive it was the second) the motor over torqued to about 400kg.cm at 10 amps and stalled in 1 second of stalling it ripped the gear reduction train apart. tearing teeth on two gears off and bending others. And this is why the motor is allowed to stall at low power to prevent damage of electronics or motor. and if it stalls it is because something is wrong. Also i have the first stable beta version of the software ("MOS" Multistruder OS). It has all the basic basic features you need to start out. I haven't really gotten into using the true power of the micro controller YET. It has the features of: turning on and off extruder/heater, setting temperature and that is about it. I opened the expansion module bundle on my website store for The Dimensional Control and Spooler/Direct drive early adopter pre order. with this pre order you get both the dimensional control and the spooler OR the direct drive for $50 bucks %50 off the final retail price. these will ship after the international units ship. I HIGHLY RECOMMEND these modules as they will give your multistruder the best possible filament output. (this turns the multistruder into what i dub the FilaFactory). this price will go up to $100 after i ship the international backers multistruder. Also this week i am putting together the rest of the units as i am waiting for the new arduino megas to replace the unos to come in. So after i get the megas i will just need to bolt them in slap the screw terminal on and we are ready to go. I am also going to need to finish some printing. I am now done with school for the summer until like late august. so i am back to full time on the project. Make sure to check out the pre order expansion modules. Picture are bellow. I included some pictures of the blown motor and a perfect 1.75mm filament segment. the rest are 2.55 or so.

23rd Week: 5/24/2016

Today marks the 23rd week of fulfillment. Bay Area Maker Faire 2016 was last weekend so some news from the show. Assembled the first 3 units to show you a good idea of what a assembled unit looks like. First beta run of the code. One issue remaining with the electronics. the thermo couple amplifier does not want to read the thermo couple but it reads its local reference temperatures so it must be just a library issue. but everything else works flawlessly. Upgrade to Arduino Mega was successful after some tinkering of the libraries. The mega barley fits inside of the case as the mega is 4 inches in length and the case is 4 inches wide. This greatly increase the expand ability of the system. i will be upgrading all units to now be standard with a arduino mega. check out pictures bellow.
