Describe your issue: I receive Unhandled exception during safe z home if I have z hop enabled. I have used this in the past without error. Only difference is that I am using sensorless homing on all axis.
I can if needed remove everything and start over, however this was happening from the start with this printer I just figured I would resolve it after I completed all my build and install. There is another bug report opened on this same issue that mentions disabling z hop with safe z home, but the whole point of safe z is to prevent a bed collision. Let me know if you need a clean install to verify.
It would be helpful if you can reproduce the error without the led_effect.py, just to make sure it really play no role.
Generally, I would not be aware of any incompatibilities between z-hop with safe-z-home. And if there were any, then Klipper should not just die but handle this with a graceful error message.
No worries happy to do this later today. FYI my symptoms are exact like the link listed below. identical, both using corexz with a switchwire and trying sensorless homing. log files are identical on where the failure happens. I was not sure since that one is closed if I should add to it. His solution was to use a physical endstop.
