Typing in MDI :

G31 X-40 F100     this works fine
G31 Y-40 F100     this works fine
G31 Z-40 F100     this works fine
G31 A-40 F100     this works fine
G31 B-40 F100     this dont work no movement , no DRO changes, no error messages
G31 C-40 F100     this dont work no movement , no DRO changes, no error messages

All axes are linear , no slave axis.

Thank in advance for any help

G31 ONLY works with XYZA.  It will never change.

Why the axes B and C do not deserve the privilege of the G31 command ??! This adds another disappointment with the MACH3 on my list , I have to develop my own touch probe system.

Thanks for information.

When Mach3 was developed most everything out there machine wise was ONLY 3 axis machines XYZ. I had to plead with Art to get the A axis included for G31. AND I  had to prove to him with valid examples that it was really needed. Same with Probe tip offsets for the point cloud.

At the time g31 for B and c was out of the question(;-)

Mach3 has 6 axes all commands should work for all axes , but that's just my opinion I have no hopes of changes in Mach3 .
