I think yours is better - as simpler design

Hmm I thought about adding a standard ratio Herringbone gear set, but those already exist :) http://www.thingiverse.com/thing:40334

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 (1.8° 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?

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

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?
