Printed one more of the spooler mounting bracket then ran out of filament more has been ordered and is on its way
i am trying to get everything printed before tech shop goes down for the month.
I will probably not be able to do that so what i will do is prototype all the big stuff there.
Print all the small stuff at home then by the time techshop re opens i will just need to finish printing all the big stuff
hopefully by then i have all the software done and bought all the wire extensions to go from the sensors and motor all the way up to electronics.
also i would like to 3d print the geared bearings. i want to try nylon for that so i use a actual bearing material used in industry. these will lead to long lasting bearings. i was thinking taulman bridge.or taulman 910 probubly 910 as it is way stiffer. we will see as i look into there mechanical properties
I checked the static stress of the shredder dials. I changed a few things and I have found that my original design is yielding the best performance. So I will not need to modify my original design.
Because I am going to be going with my original design I will not be able to get the shredder to withstand any additional stress without hardening.
MAIN POINT!!!!: TechShop informed me a few days ago that they lost their lease extension. The lease extension was going to allow them to not shut down the shop and slowly move all the machinery to the new location. If you need to use the equipment at new location you go to new location, if the equipment is at the current location use that equipment. However now that it is lost they need to do a hard close and move everything. So they are hard closing at the end of the month 1/26/2017. Also they will need to stay closed for an entire MONTH in order to finish construction on new location to be up to code and to finish moving all the equipment to the new location. so I will not be able to do production on the project tell around 2/26/2017. But the new location is going to be nice with a lot of storage so I should be able to get storage on site. They are also going to be putting together a 2nd Tormach.
Finalized the design for the spooler bracket. Printed my first one on the replicator 2 and it looks great
received my (supposed to be 10 i think 1 fell out of damaged packaging or they for got one) motors
i will continue to print out the brackets as each is so big it takes 3.5 hours to print one so it will take about 2 weeks if i print each time at closing time of tech shop.
bad news is that tech shop is actually closing at the 26th to move to larger location at the end of the month and will not reopen for a month so reopen in march.
so the idea is to print out both brackets by the time tech shop closes and print out the rest at home for the time that we have left.

Thanks for your interest everyone that came from kickstarter or a forum
The Reclaimer is currently on sale on this websites store http://www.thegreenengineers.com/store/
the starting price is $125 dollars because i was able to drop the price. i was able to drop the price because now i am milling out the shredders instead of water jetting (very expensive)
The basic unit is now equipped with 1045 steel instead of A36. This was a stretch goal but now comes included as the base model. this is because of decrease of price for steel with my new supplier so I will just include it now without extra cost
This is also a base for a lot of expansions one of which is the shroud. another is a motor, and finally a stand. The motor will need to be installed on the shroud to function so the motor will not be able to function without the shroud (for liability issues).
Where do we go from here
I now begin to optimize the blade shapes so you can cut the most hardest material possible without hardening.
I will also generate the CAM using Fusion 360 CAM for a Tormach
order the 1045 steel plates and buy the flange bearing
Production should start February and ship out late February
After shipping in February work on shroud, motor, and stand.
The $125 dollar for base unit and price increase when I start building in February and increase again after shipment in late February. so now is the best time to pick one up.
Stay in the loop by checking back into this blog often.
Happy new year and hope your holidays were merry
just went and picked up the hx711 amps and load cell
I also have servos and they look good
just waiting on the high torque spooler motors as that is on slow boat from china
because i ordered the motors that are identical to the sample i have on hand i can finish spooler module so i can begin printing those 2 at a time
still on break till the 25th. finishing up electronics then just waiting on 3d printed parts to finally assemble
Check Pictures Bellow
Motors, servos, HX711 and load cells have been ordered and on their way.
Finishing putting together the electronics boards. as I just got the bolts for Arduino mega in.
waiting on the load cells to finish design for the automatic spooler bracket then I will begin to print those
on vacation right now so I will see what I can do remotely
finished last final monday so now i am back on full time green engineer projects
just bought all the load cells and hx711 amps also i have printed both the spooler support bracket and the dimensional control bracket
the spooler bracket came out perfect as the makerbot replicator 2 at tech shop has just been serviced with a new nozzle and hot end so it prints great now
however the dimensional control bracket i used supports and they are a pain in the ass to take off. so i might need to come up with another design or just spend the time to rip off those supports
ordered more m3 bolts that i ran out of to mount the arduino megas onto the electronics mounting plate
about to order the motors. and i am going to need to order the servos and the wires to attach everything. and if it is going to be from china it needs to be fore Chinese new year otherwise a month delay
Check pictures bellow:
Built most of the electronics for the international units
found out that I need to buy more m3 bolts for mounting the Arduinos
started getting prices for the load cells and the hx711 amps
running out of options for motors except for my go to motor.
redesigned all the models to use the load cells. It simplified the models quite a bit
finally tech shops maker bot is back up for use. I will print some of the big brackets today.
also my last final is on Monday of next week and then I am back to full time till January.
Decided to switch all force sensors from FSR(Force Sensing Resistors) to load cells this increases the precision and reliability to allow for better filament precision in the expansion modules. i have received a 1 kg sensor and have started to begin testing on it. pictures will be bellow
trying to source motors from china however that not working so well so might have to go to my goto motor from amazon that i have used before
techshops makerbot is down so waiting for that to come back up to print out the 2 expansion module mounts
still assembling the base units so i only need to add on the expansion modules
Started assembling all the machines. Everything is ready to go to assemble base machine
Printing parts, and receiving electronics for the expansion modules is the only thing I left. Only expansion modules are left
Everything has come in to build the standard units. and also everything is built to put together the units
i am now sourcing the motor and sensors for the expansion modules
70% of the plastic parts and designs check out now just need to check out the big brackets
Working on a kickstarter for a plastic shredder should be launched soon and outsourced to be manufactured while i finished this project. it should be up by this weekend.
i have one last domestic backer from 2nd batch and i just finished his unit. and one post kickstarter domestic backer unit i am also working on.
that is all for now have a happy thanksgiving.
100% of machining done
100% of painting done
95% of printing done
Tuesday or Wednesday of last week i got the replacement heaterbands in. they are ready to go.
today i just got the rest of my analog thermocouple amps.
finalizing the designs for the modules as everyone is currently asking for the spooler module. (im pretty sure).
i need to finalize all the electronics and sensors for the expansion modules and order those
please get a hold of me people with support tickets thanks.
check pictures bellow
100% of metal work done
95% of painting done
95% of 3d printing basic parts done
100% of designing of expansion module
I started printing the tests for the expansion modules and modifying them as I go. I will soon order the parts for the expansion modules
replacement heater bands are on there way and I should receive them shortly
I will need to buy replacement thermocouple amps as well.
So all I need to do to finish international units is to finalize, print, assemble the expansion modules, then carefully and strategically pack and ship.
All surveys for international backers have been filled out
I still don't have units to fix from the last 4 tickets that I have. please get ahold of me to get those fixed.
Check out pictures bellow.
97.5% of machining done
95% of printing done
95% of painting done
100% of designing of the expansions modules
I have the heater bands on their way and am about to buy another order of analog thermocouple amps.
going to begin the units so I will be ready for the modules to add on and then ship out. as they take a while to find out any electronic issues
going to start to print the expansion modules in order to do final check. then start purchasing the FSRs, and Motors
UPDATE!!! I have released the survey for international backers please fill them out and get them to me asap. (I believe most have already responded)
I still don't have any broken units to fix please get ahold of me so we can get some fixed electronics back to you so you can get to using your unit.
95% done with metal work
95% done with 3d printing
95% done with painting
95% with designing expansion modules
the last thing i have left in metal work is to machine the metal couples on lathe and mill then paint them
the last thing i have left in the module design is to finalize and add a few things. then source and buy the motors and electronics.
received my last order of power supplies
just ordered replacement heater bands so i will be able to finally send out the last few domestic units. and have some backups for international
still haven't got a broken unit to repair please the 4 people that i have tickets for please get a hold of me for additional instructions.
survey for international shipments will be sent out this weekend. please make sure that if you have a change of address between the survey and when i ship please let me know.
95% done with steel work
66% done with painting.
95% done with 3d printing
95% done with designing the expansion modules about to start printing and final checking before writing the code.
Just got the rest of the power supplies in.
i am still talking to the supplier of the heater bands in order to get replacements for the 2 110v for domestic units but i have 8 220v ready to go international.
i will be sending out the surveys either the end of this weekend or next for international backers so look out for the survey.
still need a broken unit to fix this Friday please get a hold of me the 4 people that i have left with an open ticket.
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.
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.
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.
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.
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.
For the final test of moisture's effect on 3d printed surface finish. i will be testing a varying amount of moisture content PLA to get an array of filament quality to compare
cut 5 coils of Octave PLA at around 25 feet ~20 grams each
water log all 5 coils for 1 week in water
Print the 5 coils in this order
1st waterlogged coil
1 hour dried coil
2 hour dried coil
3 hour dried coil
4 hour dried coil
room environment off spool
Hopefully this final experiment gives us the final answer we have been looking for.
waterlogged filament will be starting today and will be ready fri(16)-sun(18)
