What is the problem?
I found Physical button plugin - #16 by foosel but trying the issues there doesn't seem to fix my problems.
I am attempting to setup a physical button for homing the printer.
I am running the OctoPrint Version 1.11.5 build via Raspberry PI installer on a PI 3+ Model B.
My octoprint.log is showing:
AttributeError: module 'lgpio' has no attribute 'SET_BIAS_DISABLE'
What did you already try to solve it?
I have verified that user pi is in the gpio group, etc.
I've tried the steps listed in the linked problem but nothing seems to be helping.
I have verified that the wiring is correct. I can read the button state using the RPi.GPIO library.
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
My printer starts up in error mode until it receives a $X and $H.
In safe mode, Octoprint sees the error and disconnects. As it is disconnected from the printer, I cannot attempt to home the device.
