Sherpa mini on RRF
-
Hello, was wondering had sameone used sherpa mini with rrf? Recently bought one and trying to configure it.
-
What's the question? shouldn't be anything unique to rrf about it

@luke-slaboratory
I mean values in config.g. Like teps per mm, acceleration and so on -

rotation_distance = <full_steps_per_rotation> * <microsteps> / <steps_per_mm>
solve for steps/mm, and then multiply by the gear ratio listed.

I get 705.5 steps/mm for the 10T

I started using it, but with a different motor (ACT 36HS2418). I use 710 steps/mm and 60mm/s retraction speed. All other settings like jerk and accel aren't tuned yet, but my findings will be irrelevant anyway for use with the standard LDO motor.
