Whirring/Buzzing Noise on Y-Axis

[manfred-man 0]

Hey Ultimaker,

my UM² makes some whirring/buzzing noise at the Y-Axis at certain positions.

I took a Video, you can hear the whirring/buzzing noise.

It's only when Y-Axis is moving and comes from the corner where the "Home Head"-Position is. Maybe a damaged bearing?

It's a bit annoying because the UM² is in my immidiate vicinity.

Regards

Roman

Very short video so it's hard to get a good sense of what's going on. But just a thought, have you checked if either the LED strips or the connecting wires for those strips are rubbing against the pulleys? Also try putting your finger against different parts of the print head and see if there's something vibrating there causing the noise.

I tried everyting, nothing helps. LED strips aren't loose, tested all drivebelts, cables, end stops, nothing rubbing against the pulleys. So i think it's one of the bearings.

It's only when Y-Axis is moving, the noise comes from the area of the Home-Position.

i took a second, http://youtu.be/OGwOf2_8bWo.

It sounds like a fan. But it looks like the head fans are off. The 3rd fan should be on however. If you simply turn your printer off and then on, the 3rd, rear fan should come on and the axes should be loose. You should be able to grab the print head and push it around. See if you can duplicate the noise. If so see if it comes from that 3rd fan.

Hey George,

the 3rd fan is running, the other fans are off because i was printing ABS without fans.

I moved the printhead while my printer was off. It isn't the fan, it is at specific positions on the y-Axis.

It isn't the fan mounting, i screwed it off and the noise isn't gone.

I've looked everywhere and have no more ideas what it can be.

Edit:

I checked the Ultimaker again with a college, it's definite the bearing from the Y-Axis in the "Home-Position" corner.

A case for the warranty? Maybe Sander can contact me?
