=OSE Version Design Rationale=
*Slow auger version powered by a Nema 17 with large auger.
*Vertical hang to reduce auger power requirement
*Remove flow control screw and rely on temperature and auger speed instead. PP version doesn't have speed control on motor, so motor control produces additional control required here
*
*
=Heuristic Calculations=
*We want low speed equivalent to a strong corded drill such as [https://manuals.harborfreight.com/manuals/60000-60999/60495.pdf].
[[File:cordeddrilltorque.png]].
*[[Torque Calculator]] shows this drill has only about 30 in-lb torque
*This is more like it - [https://manuals.harborfreight.com/manuals/63000-63999/63112.pdf] - 0-600 RPM, same power - means - 140 in-lb.
*PP shredder is 1770 in lb - 10x stronger - [[Precious_Plastic_Shredder#Torque_and_RPM]]
*We have experience with Lyman filament maker, 50W, 140 in lb:
[[File:lymanmotor.png|600px]]
*About 140 in lb for motor above. This should be plenty for an extruder application.
*If we take a 1A, 12V motor - Nema 17 - that is 1/4 the power of the above.
*But power for steppers apparently doesn't work like this - as that indicates 600x geardown if we consider power alone. 140 in lb is 140*16 in-oz = 2240 oz in. Then we need 30 geardown for a Nema 17 motor at low speed. That is well doable for a 3D printed geardown.
:*Note that Nema motors retain good torque at 300 RPM, so we obtain 10 RPM within the good torque regime.

BOM

  • Wood bit - 1" - [1]. 7/16" shank, as in 1/2" version. Local - [2]
  • Pipe flange - Menards $5 - [3]
  • Pipe flange - pack of 10 - Amazon - $4 ea - [4]
  • 1" pipe -

OSE Version Design Rationale

  • Slow auger version powered by a Nema 17 with large auger.
  • Vertical hang to reduce auger power requirement
  • Remove flow control screw and rely on temperature and auger speed instead. PP version doesn't have speed control on motor, so motor control produces additional control required here

Heuristic Calculations

  • We want low speed equivalent to a strong corded drill such as [5].

Lymanmotor.png

  • About 140 in lb for motor above. This should be plenty for an extruder application.
  • If we take a 1A, 12V motor - Nema 17 - that is 1/4 the power of the above.
  • But power for steppers apparently doesn't work like this - as that indicates 600x geardown if we consider power alone. 140 in lb is 140*16 in-oz = 2240 oz in. Then we need 30 geardown for a Nema 17 motor at low speed. That is well doable for a 3D printed geardown.
