21st Week: 5/10/2016

Tuesday started the 21st week of kickstarter fulfilment. wired a test electronics board and drew a wiring schematic for it welded the nuts to the motor mounts painted the motor mounts and the motor to auger couplers cut all of the metal augers to work in the machine bought 20 lbs of 4043D Natureworks PLA Ingeo resin to test all machines and for maker fiare. NOTE:!!!!! i bought those 20 lbs of resin for 35 dollars (50 after shipping). if you were to buy filament it would cost you around 35 dollars for that type of resin for a 1 kg spool (~2.2 lbs). so for what it would cost most people to normally buy 1 spool (2.2 lbs) you could make 9 out of the best PLA resin on the market using the Multistruder  (basically a $315 value for $35, now that's savings).   Maker Faire Bay Area is next week. I am going to be a exhibitor at the faire to promote the Multistruder and the filament maker technology in general. I am going to be taking around 4 Kickstarter backer units to test. The event is from Thursday setup to Sunday. So hopefully i can bring a new set of 4 units each day to test so that the week after (which is summer for me no more school) i can throw them into a flat rate shipping box and send them out for your use. check out pictures bellow.

20th Week: 5/3/2016

Yesterday marked the start of the 20th week of fulfilment. A huge week this week. Finished 85% of all painting and it has a very good florescent green color I was looking for. check out picture bellow for a look at the painted units. all electronics boards have been laid out and are ready for wiring this week I need to paint the other 15% which includes the coupler and the motor mounts. speaking of the motor mounts all I have to do is weld the nuts on, drill the holes in the extruder caps, then use a torch to get all the galvanized coating off were the heater band is going to be, then I will try to clean out the extruder. after that all units will be ready for basic electronics testing that all electronics are not DOA Then comes the long process of optimizing and adding features to the basic running code. however that process happens after I send out the units and get feedback Check out pictures bellow.
 

Nineteenth Week: 4/26/2016

Tuesday marked the first day of the 19th week of kickstarter fulfillment. Not a crazy productive week. Just doing small things to setup for laying out the electronics. Planning on painting this Friday. I decided on just shooting engine enamel and the green i get is the green i get. This method of painting is not very environmentally friendly (because of the VOC and paint being solvent based)  but i am out of time to experiment on these early units and need something quick. For the paint i am going to use transtar 2 in 1 primer, dupli - color engine enamel and ceramic (for green color and possibly for temp coating the pipe ), and transtar jamin clear for clear. the main thing i did this week is ground down all the pins on the electronics boards to allow the double back tape to have more surface area to grab onto the electronics.' pictures bellow if i have any from this week.

Eighteenth Week: 4/19/2016

This marks the 18th week of fulfillment. Another big week this week. I am still experimenting with coatings deciding between green engine enamel, plasti dip, and powder coating. I can still not get plasti dip to lay down without tiger stripping. But the green engine enamel is a little dark and not as light of a color as I would like so this week I will try white as a primer to make the top coat lighter. I also experimented with clearing primer. I will also try powder coating this week and see what kind of finish I could get out of that and analyze how much difficulty it adds with re assembly. I also layed out the electronics onto the printed electronics bracket and everything fits well, all the holes line up and the hole of the cover lines up with the TFT Touchscreen. The issue with the electronics assembly is that in order to use the double back tape the pins on the back of the board will need to be ground flat without causing a cold joint. The double back tape Is also holding very well and should create a great bond for a very long time. I just got in the shipment of the assembly wires. 1 set is Male to Male wires and the other set is Female to Female wires. The wires are 6 inches or so in total length and have 10 different colors. I experimented with sand blasting the units to clean off the slag and the rust. It takes me about 20 minutes per unit to sand blast each unit. Started welding the 2" pipe to the pipe clamps to where you needed to only use 1 pipe clamp to take the units apart. So now each pipe is associated with each unit. I am finishing up printing the electronic covers. Check out pictures bellow.

Seventeenth Week: 4/12/2016

Today marks the start of the 17th week of fulfilment. This week I got 95% of the stands done all I need to do is install the shims on the 1/4 inch plate and to weld nuts onto the motor mounts. I also might have found a suitable durable coating. I was thinking about using Plasti Dip to make a powder coat type of finish. I know that that type of coating is not very eco friendly because it has VOC and a non biodegradable surface but it is good coating to use with the time constraints I have. Later on I would like to use a biodegradable plant based thermoplastic and use it as a powder coating material. Testing should happen this week and I have about another 2 weeks from today to finish printing the covers. As a limited edition version of the units I decided to paint them a florescent green and have black 3d printed parts. These colors are Kickstarters 2 theme colors I think this would be nice for my Kickstarter early backers edition. My spray job of the Plasti dip didn't come out that great because i have ever shot something this thick of paint and first time shooting plasti dip. however you can get an idea of a color over the top of bare steel sanded with 180. Check pictures bellow.

Sixteenth Week: 4/5/2016

today marks the start of the 16th week of fulfillment. Big week this last week. The stands are now "standing" on their own. everything physical is about 90% done. i am ordering the wires to assemble today i will get it next week and i will be laying out all the electronics boards with the double back tape. I will also begin printing the covers this week. So as of right now the thing limiting the time is the printing of the covers because they take about 2 hours to print and i can only reserve the printer at tech shop 3 times a week for 4 hours a slot. So that's 6 a week and i need to print 13 or more so that is 3 weeks from now. Hopefully i will have everything laid out and even prepped for paint this weekend and then wire and test next weekend and paint if i haven't already. And hopefully ship at the end of that 3rd week from now. Check out pictures below. The picture of the cover is just a rough prototype the final version will be alot cleaner.

Fifteenth Week: 3/29/2016

Today starts the 15th week of kickstarter fulfillment. During this week i am on spring break so i will be working on this project 80% of the time. I assembled the metal for the stands earlier this week and now i will assemble the multistruders into the stands so i can adjust the motor mounts to make sure that the augers go straight though the pipe. Then i need to drill holes for the adapters so you can add another foot extension to the distance the multistruder is from the ground. Then i need to weld a "foot" onto that stand. For the electronics i need to get some 3M double back tape and a lot of wires i need to wire together the units. Then i will begin testing the units and coming up with a easy solution to paint the units that is environmentally friendly (low voc and water soluble) (hopefully). i ran out of hatchbox filament to make the electronics housing out of and just my luck amazon just temporary ran out of inventory so hopefully i find some hatchbox or some other filament soon so i can print this weekend. In the meantime i will be printing prototypes to check the fit of the cover tell it is right then by that time i should have the filament. check pictures below.

Fourteenth Week: 3/23/2016

Yesterday's starts the first day of the 14th week of fulfillment. This week i am finishing up the electronic boards and i drilled all the holes in the large 4 x 12 mounting plate. The wholes need to be tapped then they are ready to go. I prototyped out the design for the leg of the stand and it is probably not going to be adjustable or removable. soon i will get all wires and bolts in for assembly and testing then i will either ship them when they clear testing or dissemble and paint them then send them (depending if i decide to paint them or not). According to KickStarter i have received all of the surveys for the February backers. Coming up with my spring break from school so i will be working on pushing them out as asap during spring break. Check Photos Bellow.

Thirteenth Week: 3/15/2016

today marks the start of the 13th week of fulfillment. i sent out surveys for early bird backers requesting the nozzle diameter you want so make sure that you answer that survey if you are a early bird backer asap. I recently got some machined couplers in that are good to go i will get the rest in shortly. I also finished a prototype of the stand to get a idea of what it would look like after assembly. Those should be getting put together this weekend. I also plan on finishing the motor mounting plates this weekend as well. This week i started 3d printing the electronics housing plate. This is the final 3d printing part that is required to test the units. I should be finished printing all of them by mid next week. and should be starting on the printing the electronics cover that should take another 2 weeks. By the end of those 2 weeks everything should be getting buttoned up and ready to send out. That is depending if i decide to paint all the metal or not Check out the pictures bellow.

Twelfth Week: 3/8/2016

this marks the start of the twelfth week of fulfillment. This week i am still 3d printing a lot of stuff and i started fabricating the motor mount brackets. This coming weekend i will start assembling the stand and i will start to print the electronics housings/cover tomorrow. Then we should be coming onto testing in 2 weeks or so. i will be sending out the survey for your desired nozzle diameter through Kickstarter as well as other information on any other things that you need to operate your Multistruder. so be looking for that survey as i will need it to be completed as soon as possible.  Check pictures below

Eleventh Week: 3/1/2016

today marks the start of the 11th week of fulfillment. An update on the last weeks post. My motor supplier came through and got the motors to me yesterday 10 days earlier than they planned. So much thanks to my motor supplier. I also received the final necessary parts required to run the machines in on Monday as well. So now I just need to finish the 3d printed parts and fabricate the metal parts as well as test the units before sending them out. Check pictures below.

Tenth Week: 2/23/2016

Today marks the start of the tenth week of fulfillment. and unfortunately i have to bring some bad news. I recently got in touch with my high torque motor supplier in china after their break on Chinese new year and they would take up to 15 business day to fulfill the order and they estimate that the latest would be the 11th of march. This is way longer time than i planned and i am already falling behind on fulfillment to at least get the orders sent by the end of each of the months as i planned from the beginning of the campaign. So for that i am deeply sorry that i will not be able to make it to the end of the month like i promised. I will continue to work to getting these units to my early bird backers asap and for the second month backers on time. For the good news i bought all the local steel that is needed to build the units and all essential parts have been ordered/ on their way. I have already cut most of the steel to length to use on the units. i will also find a rugged and nice looking coating for the bare steel as well. check bellow for pictures.

Ninth Week: 2/16/2016

Starting the Ninth Week. it is coming down to the wire. i am busy with assembling the units. so probably what i will do is ship them to all backers for the first month of fulfillment then finish up the software the next week so that you have a week or more (should only take 30 minutes to assemble) to assemble and then the software will become available or i will just finish it with the software. however the software will have a lot of betas the first couple months probably a update a week to add better performance. so i will probably do the one week thing i guess we will see. I am just really behind on the software. The hardware i am schedule to get them out by the end of this month or so. i also finished printing out all of the filament cooling bracket mounts at tech shop as my own 3D Printer Kossel is down until i convert it to a delta. please see pictures bellow.

Eighth Week: 2/9/2016

this marks the start of the 8th week of fulfillment. I have finally started to put together the units from all the parts I have received. More packages are coming in every couple days. We are still on track delivery at the end of this month for the 14 early bird backers or late by at most a week or so. 1 out of the 4 main parts that need to be fabricated are finished. The 2" coupler have had the 3/8 mounting nuts welded to them and now the 3/8 all threads can be used to mount the motor mounting plate which will be made next. check pictures below

Seventh Week: 2/2/2016

this week starts the seventh week of fulfilment. I only have stuff that needs to be ordered after the Chinese holiday left. Those items are the Motor, Arduino, TFT, Stylus, ( and misc stuff). I now have enough components to layout the electronics mounting plate with all the components on them. A few more things have come in this week and i have also worked on more of the "MOS" System (Multistruder OS). I broke down each large part of the program into a individual h file for easy editing. Those files will be available soon on this site for downloading to your Arduino your Multistruder uses. You will also be able to find ubdates to the "MOS" system here aswell. Attached are pictures stuff that came in this week.

Sixth Week: 1/26/2016

Most parts have been received or on their way. However some of the parts have been held over to be sent after the Chinese new year holiday and that wont be tell 2/15/2016. So the first set of early bird fulfillment will be cut pretty close to the end of the month of February. I will have all pieces that i can build now built and be ready to accept the parts that will be coming next month. Also a final production prototype will be built.  Check out the picture below of some of the parts and samples i have received

Fifth Week: 1/19/2016

start of the Fifth Week of fulfillment. As of right now all samples of all desired parts that need to be sampled have been ordered. All other products that do not need sampling have been ordered in bulk quantities. So already half the parts have been ordered and all the others are currently being sampled. So we are still looking at being on time even though a impending complication is on the horizon. A lot of the parts are being sourced from Chinese manufacturing companies. Their is a major holiday festival on the horizon in china. Chinese New Year starts on Feb 8th and will last a total of 23 days were Chinese workers do not work (according to my knowledge) for the duration of the festival this also includes the curriers. This means that all parts will have to be shipped before the 30th of January. so by the start of the Sixth Week everything should be ordered and manufacturing will begin.

Fourth Week: 1/12/2016

Fourth week of fulfillment has started. Parts have been basically finalized. So number 1 on my list is down. I have now gotten some sample orders shipped. In this week all samples should be shipped. Some batch of parts that i know that can be bought without samples will be shipped. We appear to still be on track to deliver when promised. Stay tuned for more updates.

Second Week: 12/30/2015

Starting the second week of kickstarter fulfillment. The kickstarter funds should be coming in Wednesday the 6th. Then I will be ordering the remaining electronics to finish the prototype. I will also start shipping in the electronics that have already been tested and finalized for the production models. I am currently still vacationing with family I should be done with vacations this holiday break by this Saturday and will be back on the project full time until I get back into school 1/22/2015. I will also renew my membership at the local San Jose Tech Shop were manufacturing of the production models will talk place. Talk to you guys again soon enjoy the rest of your holiday break.

I Will Finish a Production Prototype First

Im going to be finishing a production prototype first whenever i am home. Then i am going to order the parts in bulk. This is because i am finding that i nee more items in the Bill of Materials that i didn't foresee. So i want to catch all extra parts that are needed first. However i do not have a lot of time either to get the parts shipped in time to assemble units. I do think that you guys would want to see the Production Prototype rather than just hearing that i had all the parts shipped.

Wrote a Basic Checklist

Wrote a checklist on what needs to be done for the fulfillment. Finalize Parts Order Part Samples Source Local Metal Stock Build Final Production Prototype Order All Parts (decided to switch order of these two) Finalize "MOS" Beta Build Units Ship Units Release "MOS" Updates Finalize The Spooler and Dimensional Control Modules Sorry about the atrocious handwriting. Just wondering if next time I could just post the picture of the writing on the white board.

First Week: 12/23/2015

Project was successfully funded at 100% yesterday the 22nd of December funds should arrive in 14 days from now. I am going to be on vacation with family for another 8 days. So I will be working on the software, website, and finalizing the parts (and getting samples of those parts shipped) whenever I have free time in those 8 days. When I get back in town I will be finalizing the prototype and electronics software (beta) and sourcing local metal supplies. Also HAPPY HOLLIDAYS and enjoy some time off with loved ones and keep track of this fulfillment blog and the Multistruder dev blog as these are the places I will be posting updates.
