Not sure if this is “normal” for Mario, but randomly tonight, after homing, I got the following error:
Error: 15 - Jog target exceeds machine travel. Command ignored.
Then eventually it worked. Then I decided to do one more thing & started having this error again, so I gave up & went home.
If you didn’t home it or were trying to do something that would cause the head to go out of bounds, then it is normal. Otherwise no, it’s not normal.
But it does seem to get stuck throwing that error sometimes, and it seems like it’s happening more often recently. It’s probably time to order a replacement controller for it.
