Y-Axis Stepper Motor Unresponsive
Hey Prusa forum!
I'm having some trouble with my MINI+. When printing something today I noticed that the Y axis was not moving at all during the print. When starting the homing process, the motor made a "clunk" sound, but didn't move at all. It made the "clunk" sound a couple more times when trying to restart the print, and using Settings > Move Axis. After that, it's been completely silent and unresponsive.
I checked the linear rails for obstruction. They all move to their extents, but the Y-Axis is a little harder to move than I remember, like the motor is resisting a little. I lubricated the rails and checked for disconnected or pinched cables, disconnected and re-connected the Y-Axis stepper motor. I also checked the belt tension (taut but not as tight as it can go), and set screws, which were tight.
Now when I boot up the MINI+ and go to Settings > Move Axis, "Move X" shows 180, and "Move Y" shows -3. Changing the Y value has no effect and no sound comes from the motor. Similarly, Auto Home doesn't move the Y-Axis, nor does starting a print.
Is it possible my Y-Axis stepper motor has gone bad?
Wrong wiring or burned motor.
The best way having the printer under warranty to contact support via chat from eshop Page.
One reason can be a high y axis bearings friction friction. Anyway the y motor should try to move and you should hear a skipped steps of the motor.
You can also check the y motor wiring- if you did not received your printer fully assembled?
When you are setting the y motor do the values on the display change?
Try the factory setup.
even an old man can learn new things 🙂
