Strange shiftig occurs after a certain height of the prints. Observe the flawless printing for the small brain, while the large brain suffers from artefacts starting from a certain height. Also, the belt of the motor on the back left gets loose every time, although I straightened it by pushing down the motor and fixing it by tightening its screws like hell.

Any ideas or suggestions would be highly appreciated!

Marc

    Umo+ in theory (unless if it's summer in spain) stepper motor chips can't get hot enough. Try to check the calibration. Adjust the pulleys and check the small belt tension. I can print very fast with aceleration at 2000-2500 and travel moves of 200. Of. I changed my belts/pulleys to gt2 but I been using that speeds with the mxl stock without problems.
