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.

Update: Want Unit Early?

Hey guys if you would like me to send your basic unit to you while i finish work on the modules let me know and i can send them out to you asap. then i can send the modules out to you when they are finished. First come first serve. Otherwise hang tight and i will get them both to you at the same time.

Update: 9/7/2017

This week I tapped all the couplers mounted all motors to their corresponding brackets with thrust bearings and couplers installed filled down the hard edges of the auger so they are now ready to install. Continued to work on the primary testing machine. more work to come. I am sick this week.

Update: 8/28/2017

This week i have cut the augers down to appropriate profile. Also i have ordered and recieved the screws that i need to put together the units. Today i plan on tapping all the holes on the couplers for the motors. Hopefully soon finish the unit that someone requested early and get it out. and see how it fairs shipping overseas. Then i will adjust further shipments international accordingly.

Update: 6/29/2017

Hey guys sorry again for the radio silence. The reason why i have been gone is i have picked up a summer job to get some more funds for my project So here is a deal i am thinking about the fastest way of getting these out to you. This weekend i will be coming up with a solution. What i was thinking was to ship out the base model to you guys. Then shipping out the modules and me just bite the financial bullet of shipping 2 boxes. Also i dont think the entire thing will fit in that box safely. It would probably fit just not safely.

Update: 3/7/2018

work at school and the machine shop has been kicking my ass. I am dropping hours at work to give me more time twords my green engineers projects mainly this project. So these past 2 weeks i have been dealing with midterms but now i am in the clear for a month. i have got 90% of the spooler module printed (in various colors). Which includes the winder. drive and driven cones, and just printed the bar to attach the pulley. The last parts to go onto the spooler module are the pulley and the adapter to be able to mount and adjust when installing on the stand of the multistruder I will now be coming up with daily plans for the weekend on what is to be accomplished each day. I will write down on my day white board the next 3 weekends and extra 1 day of what will be accomplished each day. An idea of that is i need to finish the spooler. Then start working on the dimensional control module (first finding where my prototype is). Then assembling. then working on beta of code then final installment of the code Maker faire Individual assembly testing and ship repeat i will post this shcedule bellow and also the pictures of the machine and its parts that are on my desk. Check pictures bellow.

Update: 12/20/17

As of yesterday i am now off of school for the winter. Till like mid January Finalized the 3D Models Now need to work on the software. Put together a beta. assemble prototype.then assembly Going to be putting together a workshop in my garage since i lost my shop at tech shop. Also going to be getting a metal router that i might be able to use for this project as well

Update: 11/30/17

Been working from home Got my printer to work again and it is doing some perfect  prints Unfortunately it prints really slow (40mm/s) So far i have finalized the drive cone it slips on motor perfectly This week i hope on finalizing the servo rack and pinon Then i start working on software then assembly I did check out a few locations to move the shop to but nothing has panned out yet. All i need to finish this project i currently have available to me. Other projects not so much.

Update: 11/13/17

A lot of progress this week The assignment for using a portion of this project for class has been approved. Hall effect sensor for speed is project for class using parts from my project I have found a printer at tech shop to use now that does great prints pretty quickly (afinia h600/up) Bellow is what i got done this week: Finalized drive cone and how it attaches to the motor and spins spool Got cork sheet to increase friction between the spool and the drive cone Printed prototypes of pulley, pulley bracket, pulley bar, servo rack and pinion and mounting bracket for servo finalized the pulley, pulley bracket and the pulley bar. Rough assembly of the servo rack and pinion and bracket finished. just needs a few tweaks. got motor attached to dimensional control bracket.  Also got to check the hall effect sensors and the permanent magnets to electronically work with each other. So now just need to add the logic behind it. Also i purposed this project to be put into a competition so i can show ti off and also get some teammates to work on ti with me to speed it up. Winter vacation to start here soon. 5 weeks or so. so after family vacation back to full time to hopefully have everything finalized by the end of the year and to start assembly.

Update: 10/28/17

Finished Assembling the Dimensional Control Module It still need a few tweaks but that will happen slowly over the next few weeks Tomorrow i am going to submit a proposal to have the designing of code and getting the sensors working be a project for a class Hopefully that clears so i can spend a class lab time working on the sensors and outside of class work on the mounting if that goes though then i will have a extra day 5+ hours added to my development dedicated directly to getting sensors and code working. tomorrow i get the parts to start working on the spooler module and finding and buying the hardware and materials for that.

Update: 10/2/2017

I have made a list of the things that are left to do. and i have been getting things done in order. image will be posted bellow. I shiped out 1 unit for a backer that wanted his unit early before the modules to play with I reinforced the hell out of the box to ensure that it was going to make it to Germany in one piece. We will see how it fairs. 3 out of the 10 things have been checked off from the list and i now have dedicated days per week to the project now. as i have money coming in from contract work else were. What you will see from number 1 and 2 from the table is that i finished a way of mounting both the expansion modules to the frame and fixed the mounting bracket onto the modules. Then yesterday i got most of the supplies to assemble the modules. these early steps are the easiest and as they go down the list the time required gets more.

Update: 10/15/17

Going to try to make updates weekly again. Printed a new version of the dimensional control bracket bought parts to put together the bracket and all pieces to mount the rollers and the strain gauge. Then put bracket together wrote down changes that were used to make amendments to dimensional control bracket So as far as my list we are at 4/12 steps.

Update: 1/23/18

Got everything working. in code and physically have been putting everything together in code. I have a few more things to bring into code. Hopefully this weekend i can add the modules to a pre build multistruder downstairs. The priority is the spooler and the dimensional control. The RPM sensor is last. I start school again tomorrow. I will only be taking 6-9 credits this semester. so only part time to almost full time.

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

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.

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.

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

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.

Situated In Office

i am finally settled in in office. mostly everything is transferred however some things got lost in shuffle so i am repurchasing everything that i could not find i started assembling units. also looking for help from a intern to assemble. soon you will see a picture of them all assembled.

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.

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.
