Axle moving

[Mick_cologne 1]

Hi, my ULTIMAKER 2+ has the problem that one of the axles (only on one side) moves back and forth by about 2mm when the slide that moves on that axle is moving fast (s. picture). I suppose (close to being sure) that one of the pulleys has moved, although there is no visible slip during printing and the prints are good!?

Thanks for the answers in advance!

Just a guess, but seems like the set screws on those belt wheels (gears) on that axle are not tight.  If they are tight, I think the axle should not move back and forth.

 

I would gently move the print head away from the belt wheels zone til the belt wheels set screws are easily accessible and then tighten the screws on both belt wheels and see if that stops the sliding.

 

Hope this helps!

I think I will loosen the screw, move the axle with the other pulley to its stop, then move the loose pulley to its stop (distance tube) and the tighten the screw - done!
