Ultimaker 3 Lift Switch squeaking

Recommended Posts

Posted · Ultimaker 3 Lift Switch squeaking

I have a problem I've not seen discussed. Every time the printer completes a layer with PrintCore 2 and raises it, it makes this loud squeaking/squawking sound--almost sounds like an evil laugh. I'm attaching a short video of this.

 

I had noticed something similar after a while of printing PVA support with a BB core. Then I started using Breakaway with an AA core and the sound went away for a while. Now it's back.

 

In neither case did there seem to be any problem with the prints.

 

The lubrication guidelines only talk about oiling the metal parts. Is there lubrication needed on this switch? or is the sound coming from something more internal to the print head?

 

I've shared the video on OneDrive

Does it squeak if you push it manually?  If so then maybe you need to add some grease?  if not then I'd run the cal procedure for that lifting mechanism.

It does not squeak when pushed manually. However, I've noticed a white scratch forming on the part that connects the gantry rod to the belt. It seems the switch is scraping against that part.

 

I'll try running the calibration.

I ran the calibration and made sure not to push it too far to the right. Problem solved.

 

Thank you.

Yeah, calibration procedure it says to push it in firmly but then I back it out by maybe 1mm to the left before setting the position.
