    • 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.
    • This week i was finally able to get my feeds and speeds right to finally cut an entire sheet efficiently.
    • This next week will be considered the first week of production for all the parts of the shredder.
    • The feeds and speeds will be tuned further for the machine i am using to finish the full sheet without stopping (efficiency improvement)
    • Hopefully the efficiency gets to a point that an entire shredders parts can be finished in a day (4 hours reservation on machine).
    • Next week i will order more 3/4 inch drive shafts.
    • I forgot to snap photos before i left the shop today so i will do so tomorrow.
    • machining to begin again monday.
    • The Green Engineers now has an office of operations in the basement of tech shop
    • it is a 8' x 12' "maker cage"
    • it is where The Green Engineers will be operating out of until upgrading to a larger cage
    • I will now be building stuff and designing stuff out of the cage
    • it was mainly rented to allocate all pieces and tools in one place as well as building production machines for the cage as well as being at tech shop to access their production machines.
    • Added ssd to old laptop and now it will be there permanently
    • also got 2d printer for shipping labels
    • and my Trinus 3D printer

    Check bellow for pictures of the cage progress









  1. 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
    1. 1st waterlogged coil
    2. 1 hour dried coil
    3. 2 hour dried coil
    4. 3 hour dried coil
    5. 4 hour dried coil
    6. 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)

    i have been messing around with adding the code for a more dynamic temperature control to bring down the hysteresis to 1 degree up and down. to allow for a very higher precision of control. unfortunately i cannot really test it out because i don't have a unit to test anymore. I have one left over in the garage that i will put together until then i will just be working on the code side. v1.1.1 is just me working on it. v1.2 will contain those changes.


  3. ok i have taken everything apart (removed everything from the frame). I can now get a better look of what i have to work with. I have

    • 2 ~11.25 inch chromed rods
    • 4 8 inch chromed rods
    • 1 9 inch lead screw with brass nut
    • 6 LM8UU linear bearings
    • 4 NEMA 17 motors
    • various bearings for belts
    • 2 NEMA 17 pullies 
    • 2 GT2 belts
    • 1 hobbed pully
    • 1 100 watt power supply
    • 1 printr board

    that's about all the useful things i have from the carcass

    check pics below

  4. like i said in my first post the idea is to build a entire 3D printer frame off of the 3 700mm 27" uprights all the extrusion motors and all the other brackets and such (i will have to get another extrusion motor for the x carriage). So the main idea is to use as few additional parts that i have to buy and print as possible.

    Look at the drawing attached for a better idea of what im going to do. i know it is messy as i have rewrote the plans a few times.
