Hi and welcome to 3DP.SE! You basically established that X and Y only work on the Z header. Have you checked the endstops (e.g. inverted logic or incorrectly wired; try pressing an endstop switch when moving the axis, also note to home the printer first)? Also note that the extruder will only move when it is above a certain temperature, usually over 170 ºC. Please update your question by [edit] to include additional information that is asked through the comments.

also, how long did you have the printer running beforehand?

It sounds to me like the firmware may have become corrupt when the power supply popped... It's the only thing I can think of that would cause this bizarre behaviour! If you have an Arduino there are plenty of tutorials that explain how to reflash the firmware.

updated question with more info regarding firmwares, thanks !

Maybe the question should be: "Is it possible that blowing my printers power supply wrecks up my printer?"

@0scar you might be right. i loaded the stock (unsafe) firmware on the creality3d repo just to make sure it wasnt the firmware and still the same issue. goes to start testing capacitors / resistors and see if i can find something there.

# X / Y axis + Extruder not working on respective ports

(Asked by: username_0 on 2019-09-17)

On an Ender 3, the X, Y and extruder are not moving when using the prepare menu to move them. If I change the motherboard port for Y to the Z port, the Y moves fine, same goes for the other axis that are not working in their respective ports - so it's not the motor or the cable. What else could be wrong? I find it unlikely that 2/3 axis and extruder are all stopped working at the same time.

I have tried "auto home" but before anything moves it says "Homing failed PRINTER HALTED Please reset". The y axis seems to have a light humming noise to it, but no movement at all.

Seems like all of the stop switches are being ignored. When I "Home Z" with any stop switch plugged into the Z-stop, it just continues along even when i trigger the stop manually. This eventually means it hits the end of the axis and just keeps hitting the end with a nasty vibrating sound.

It was working for about 6 months before all this and my old power supply popped, replaced the power supply and all this started.
