If you run into issues with Klipper Errors such as
unknown sensor 'temperature_fan chamber'
unkown sensor 'temperature_sensor chassis'
after attempting to run newly generated gcode after updating your slicer profiles, you will likely need to update the config file on your machines to be able to run the new gcode.
The start gcode in newer profiles utilizes temperature sensors and fans that haven’t been enabled in older machine firmware.
