I made these gears to reduce the gear ratio for my Ultimaker. It makes the retractions completely silent when paired with SilentStepSticks stepper drivers (and operated at <20mm/s). Don't forget to change the Estep parameters in your Controller or firmware to 530.1 from 865.8. For best results print at <50 mm/s and turn on combing in retraction.

I think yours is better - as simpler design

Hmm I thought about adding a standard ratio Herringbone gear set, but those already exist :)

Good, although my little cog isn't as good as yours
Good job. Perhaps you may consider doing a herringbone for the standard drive ratio for simplicity/ robustness?

Nope! There are normally four values which influences the step-width: the microstepping resolution (hardware, changeable by the jumpers on the mainboard), the e-steps/mm value (firmware!!! that means MARLIN for the UMO), the stepangle of the stepper motor itself (1.8Β° for the stock Stepper) and finally the ratio if the Stepper is geared.

To be exact:

You CAN also influence it by - e.g. the flow value - but that's not the "normal way".

To take it short: dont worry about your slicer

Thanks Ataraxis. If I were to use another slicer such as simplify 3d would it make any difference?

Mini ataraxis glow bigataraxis commented ago

Using the ulticontroller: control -> Motion -> e-steps/mm

How do you change the estep parameters. I'm using a UMO with a heated bed and cura

Mini 1001088 10151492180506330 861057211 nAlex Nikolaev commented ago

Yep, exactly! Even after installing Silent step sticks, the feeder continued to be quite audible (51.3-51.7dB at 40 mm/s retraction). In order to reduce the noise I had to reduce retraction to below 10mm/s. By reducing the ratio I was able to boost that speed up to 20mm/s and continue to operate at a comfortable 29-31dB noise level.

Thanks for sharing your design! But tell me... why did you changed the ratio? For noise reasons?
