Overtravel on G28

[Dirty25RS]

All my programs are over traveling at a G28 command. We've been using this command for years I don't know what changed. I am not the only one that operates the machine, others do, so I don't know if someone changed something.

Example of code up to failure:

N5 G21
N10 S100
N15 M19
N20 G91 G28 Z0.
N25 G28 X0. Y0.

Any ideas?

If you perform a manual homing, does it alarm out?

Maybe trying to restart the control while pressing P+CAN and rehome the machine.

Does over travel occurs for all axes or just one ?

We fixed it.

That G21 should have been a G20...I guess...because now it works.
