I am building a Laser Engraver. I have Uno and CNC Shiel v3. I have NC Optical switches. I configured $5=1 $21=1 $22=1 In config.h I have: #define HOMING_CYCLE_0 ((1<<X_AXIS)|(1<<Y_AXIS)) My switches for X and Y work when tested. UGCS Platform shows ALARM:Z Will not perform HOMING Any help appreciated.
You should have #define HOMING_CYCLE_0 (1<<X_AXIS) #define HOMING_CYCLE_1 (1<<Y_AXIS) as per gnea/grbl
Thanks for the reply. It still shows that Z is in alarm ALARM:Z, but it does home now. First X, then Y.
Grbl itself doesnt have that alarm: gnea/grbl It could be your host? Try OpenBuildsCONTROL (software.openbuilds.com) just to rule if its maybe UGS being weird?
