Hi everyone,

I also have a cg4 assembly, I put the onstep on it, it is working 100%

Resources:

Onstep 

2x DRV8825 drivers, 2x 17HS4401 steeper

Support for nema 17

perfectly.

For AR a 3:1 (60T pulley to 20T) gear

for DEC 2.1 (40T pulley to 16T, bigger impossible)

A shaft extender of 6mm 

sometimes it doesn't stop directly at the target, the error happens in the DEC.
use a version with arduino mega 2560.
Thanks.

The solution to your question is the AXIS4_DRIVER_POWER_DOWN parameter. The comment is pretty self-explanatory and it is also documented in the configuration Wiki.
