Maslow stops, complains about Z

Troubleshooting
1

Hi All,

I have a 4.1 that I broke out of storage for the season. I set it up and intended a cut. It started but then stopped 5 minutes into it. It would no longer respond to jog commands. Here is the serial code. It seems to have stopped after motor current warnings. Any clue?

Also, this version keeps warning about my Z axis being too low even when it is not and I set Z home (which should set it to 0.

I suspect your spools are binding. You probably have a red led light on the control board.
You will need to power off and on to recover, which will also probably mean you will have to disconnect belts and retract, extend and reattach belts then apply tension.
You may need to sand and lubricate the spools.
What retraction force is set?
I see you have loaded the latest version
To reset Z you need to lower the Z all the way, put blocks under the Maslow so Z can go right down, then go to Setup, Set Z stop, You can then raise the Z to where the bit is just touching the work piece and set Z home.

The fact that it is top left and bottom right also points to maybe the anchor location points being off. Any chance that something moved in the off season and it might need to relocate the anchor points?
