It’s been down for the last few months due to “driver issues”. Was told last weekend that it /might/ be a board fault and that a bunch of parts (mainly pin headers) needed to be swapped to a donor control board.
Took the boards home and did the desolder, swap and repaired several damaged pads. Reinstalled the replacement this evening. Testing as follows
X-drive circuit test (both directions): PASSED
Y-drive circuit test (both directions): PASSED
Z-drive circuit test (both directions): PASSED
Extruder circuit test (both directions): FAILED - Does not respond to manual control
Bed temperature test (does it turn on): FAILED - OctoPrint won’t keep settings
Extruder tip temperature test (does it turn on): FAILED - OctoPrint won’t keep settings
An audible hum could be heard and the extruder motor is getting rather warm. I need someone to verify that its driver is working.
The fan for the extruder motor has worn out. It needs to be replaced.
Vaughn has cleaned up the shelf with the printers and added new lighting. Be aware the new overhead LED lamp also powers the RasPi using the USB port.
