Ultimaker Original Z axxis Problem

[panosna 0]

Hi everyone.

 

I have an Ultimaker Original, which I bought brand new a few years ago. 

 

Today, a problem appeared. It seems that the Z axxis moves the bed only up and not down.

 

I don't know why that happens. Maybe the Z-motor is damaged? But if it is damaged, wouldn't it move at all?

 

 

Any ideas?

 

Thanks

Have you tried to move it from the controller to check?

Yes, I tried to move it from tha controller and it only moves up and not down.

Could you try to change it with another steppermotor (so put the z axis in the slot of the x axis) and try if the z axis is the problem or the driver?

Ok, I changed the Y,Z wiring and it seems that the Y doesn't work correctly now.

 

So, that must mean that the motor has a problem?

If it is the bed that keeps acting strange the problem is in the motor. If the problem shifts to a different motor it is the stepper driver. I am not fully clear what you mean with the Y does not work.
