I have a Monoprice Maker Select Pro Ultimate 3D Printer (wanhao parts)
My machine stopped working properly, the LCD screen is blank, signal is being sent to the motors making them click every 5-6 seconds… the LEDs and the cooling fans operate.
I searched online and it seemed that the issue is the power supply. I tested the power supply and it outputs 24V properly, however I replaced it with a new one just in case… it did not fix the issue.
I imagine the only issue now would be the main board or the control board. I tested continuity in all connections, checked the relay and every capacitor i see… they’re all putting out the correct numbers.
I guess I have to replace the main board?
