I am having trouble with my UM3.  The UM3 is making a vibrating noise of the x and y steppers.  Please advice.

 

Cheers

Hi and welcome,

 

Looks like the endstops are not triggered when homing.

 

Check if they are activated (you can do this by sliding the head with your hand in both directions (x and y) and reaching the home position.

 

You should hear a clicking sound, if not then check why it's not touched

Hi Didier,

 

Yes that was the issue, the Y axis switch is not working. Please advice on how to repair.  

 

regards

if it's the y switch, it should be activated by the axle. You can pop it out of the sliders and move it a bit so it touches. 

 

Don't move it to far or it might touch the z rods

Still not joy.

if you move the head in the front right, 

 

Prepare to click the y switch with your finger (or a screw driver)

 

Then home the head (using the controller). 

 

Before it reaches the home position click the switch it should stop going to the y direction.

Done tried that, no response from the y switch.  The x switch works.

And did it happen suddenly or did you for example take the feeder motor away? (could be a pinched cable).

 

You can check connections on the mainboard also.

 

If everything seems good then you should probably replace the endswitch (contact your reseller)

Ok will look.  It just suddenly jumped, that was it.  The spool feed got jammed.  Maybe that what affected it.

 

I will contact my reseller.

And you took the feeder motor off? Check for cables that go behind that motor
