Different parts and it occurs at different heights.
To check if it's heat (room temperature below 28C shouldn't give any trouble) take out the wood cover and place a fan hitting the board.
Did you screw all the pulleys including the ones less accessible on the motors?
Sounds like a mechanical problem to me belt slipping?
This is an EXTREMELY common problem but without a photo I'm not sure what you mean. It slips BOTH X and Y at the same time? That seems extremely unlikely. I'd really like to see a picture but here's one for you:
3rd photo down on right - bright pink. Like that? Sort of? That's loose screw on pulley - usually the one on the motor or just above the motor. Tighten the hell out of those screws. If you use an L wrench your finger should hurt a lot when you do it. You should twist the tool slightly - you should be afraid something is about to break. ALL SIX SCREWS on the axis that is slipping.
UMO kit ships with replacement screws that are shiny silver. The ones in the pulleys are black. The shiny ones are much better (pointier) although I've been happy with the black ones because I TIGHTEN THE HELL OUT OF THEM.
same part? or every part you do?
