I think I have tracked my problem down to the ABL probe. It seems to over extend which results in a crash. I readjusted the extend and retract angles. I tested these by running a g28 and then a g29 and it worked. I shut down the printer.

The next day I ran a print and it failed. Looks like the ABL probe is using the old values even though the firmware has been updated with new values.

Ideas on where to start?
Did you compile and uploaded the firmware after changing the servo endpoints?

Try testing with this, making sure the probe ends up where you expect

M401 - deploys the probe
M402 - retracts the probe
