I have a Stronghold Pro with the BB 32. I recently changed the inductive switches that came with my machine to the Openbuilds limit switches to have auto squaring possibility. I flashed the BB 32 firmware with a build generated through http://svn.io-engineering.com:8080/?driver=ESP32&board=BlackBox X32 . When I start my machine and press the Home All button in the Control software my machine is homed and squared as expected. Everything else, like starting a job or jogging the machine works as well. However, if I press the Home All button again I get the following error and crash. Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

I simply disconnect and reconnect and I can then home again. Any idea what is causing this?
Inductives don't work so well in parallel. For autosquare we'd recommend Xtension Limit Switch Kit That does look like a firmware bug, so might want to report it here instead Issues · grblHAL/ESP32
Indeed, that's what I did after finding a topic on the subject matter on this forum. My limit switches are from the Xtension kit. Out of curiosity, how accurate/repeatable are these switches? I've opened a new issue on github. Thanks!
Very good, definately better than inductives (they are temp sensitive - temperature rise affects the B(H) curve of the magnetic core, etc - not always very repeatable). Inductives only really better in being waterproof if thats a requirement for a particular build, but otherwise a lever switch is more precise.
