@Nordle said in Single Axis multiple stepper with different steps/mm possible?:
@dc42 I didn't. something like this first I could find on aliexpress? Are they in holding position when no power is applied?
Normally the brake is engaged when power is not applied. Applying power to the brake solenoid releases the brake. RRF 3.4 and later support motors with brakes, see the M569.7 command.
Make sure that the brake solenoid voltage matches your VIN voltage. 24V is typical.
If your machine suffers a sudden loss of power, the brake may not engage quickly enough to prevent a slight drop. Using M18 in the M911 power fail script may speed up application of the brake, especially in RRF 3.5.
