How to free up a specific pin (RRF 3)
-
I am currently trying out RRF3. I wanted to free up the pin used for homing my B axis so I could use he same endstop for the C axis. But I always get the message that the pin "ystop" is not free.
I tried
M574 B2 P"nil" M574 C0 P"nil" M574 B2 S0 P"ystop"
for the use as the B axis and vice versa for the C axis, but it is not working. What am I doing wrong?

Ok I quickly found the solution myself: I had to free up the pin from the Y axis even though I didn't assign the endstop to it:
M574 Y0 P"nil"

I'm glad you solved it. See https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Default_pin_assignments for the default pin assignments.
