I printed three pieces a day without any problems. Then I turned off the printer.
The next day I turned on the printer ... but nothing happened. Printer is dead. When I connect it to the PC via USB, the display turns on, but the motors are not powered.
A quick check showed that the power supply was interrupted.
What can I do or how do I get a new power supply?
Power Supply Problem with Prusa I3 Pro W
Re: Power Supply Problem with Prusa I3 Pro W
Hi，you can check as follows:
1. First, check the connection of the motor to see if it is connected incorrectly.
2. If the connection is correct, you can swap the motor driver or motherboard interface to see if they are dead.
3. If the connection is correct, you can swap the motor wire to see if it is dead.
3. If the connection is correct, replace the motor with another axis motor. If the motor still cannot rotate, the motor is dead.
Hope can help you
