SOLVED How to free Stepper Brake pin?
@dc42 - We're hoping you can help us out. We are using the following to set the Stepper Brake for our printers running 3.4b5
;=========================================== ;== Stepper Brake ========================== M569.7 P0 C"0.out1"
What we need is a quick way to free that pin on our workbench to disable the steppers brakes during assembly. Here is what we are using but the M950 P0 C"nil" isn't working..
M950 P0 C"nil" M950 P0 C"0.out1" M42 P0 S1 M18
Is there something wrong with the command to free the pin? Or can you not free the pin once defined as a stepper brake? The only work-around we've found is to REM that line out of config.g and re-run it, but that's quite cumbersome as it resets a lot of other variables we've setup for testing. Thanks!
@oozebot have you tried this?
M569.7 P0 C"nil"
@dc42 no, not yet - didn't think/know to try that. I'll report back after testing on the next machine that frees up. Thanks!
@oozebot the rule is that to free up a pin that you previously allocated for something, you use the same command that you used to allocate it, modified so that it no longer needs the pin.
@dc42 That worked - I guess we should have assumed it was that easy. Thanks again!
