Hello,
Hmmm, try checking your soft limits to see if you have configured them correctly, or if you currently have them enabled.
Limit switches will always disarm the system regardless of what kind of motion is being performed, or even if the machine is idle. Because MPG jogging works, then it may be something different.
As a side note, the only exceptions where limit switches are ignored are as follows:
1. When a limit switch is also configured as a home switch and the machine is homing.
2. "Limit override" is enabled in Mach.
If the soft limits don't work, then please post, in exact words, the error that you were given.
