Starting our monthly maintenance thread since I didn’t already see one. As a reminder, we decided to try keeping a running thread through the month with maintenance-related items regarding the 3D Fab area (not to replace creating an issue – just to keep up with what’s going on in the area).

Was printing on Poly Printer .91 today and the filament switch kept failing (it would stop the job although the wheel was still engaged and the filament in place). Tried jiggling it and noticed that the switch is quite loose (might need to be replaced) but unfortunately that seems to have restarted the marlin firmware (my incomplete print stopped and the Octoprint terminal shows the Marlin firmware handshake):
