I am diagnosing some homing issues with my printer.
For the Xmin/Ymin/Zmin indicators on the Diagnosis screen, if the limit switches are not depressed, we expect these indicators to remain lit continuously, correct? On this screen for my printer, the indicators will flicker off every few seconds. If this is unusual behavior, I expect I have a wiring issue or something wrong with a controller board. If this is normal, perhaps there is something else.
