I will check tomorrow at once I’m at work and I will be posting several serial logs so you guys can give it a look and let me know if I’m missing something. i thought giving it a rest and coming back fresh might help but still nothing. thank you and David for helping out. ---

The thing that pops out to me most is these two: ```auto [MSG:INFO: All belts extended to center position] [MSG:INFO: Retracting all belts] [MSG:INFO: Top Right pulled tight with offset 0.258] [MSG:INFO: Top Left pulled tight with offset 0.075] [MSG:INFO: Bottom Right pulled tight with offset 6.485] [MSG:INFO: Bottom Left pulled tight with offset 0.172] [MSG:INFO: Extending all belts] [MSG:INFO: All belts extended to center position] [MSG:INFO: Retracting all belts] [MSG:INFO: Top Right pulled tight with offset 0.193] [MSG:INFO: Top Left pulled tight with offset -0.021] [MSG:INFO: Bottom Right pulled tight with offset -6.646] [MSG:INFO: Bottom Left pulled tight with offset -0.032] ``` In both of those the bottom right belt is off, which would fit with a magnet slipping. The part that I can’t figure out is why it would be off by exactly the opposite amount the second time. That feels like something else to me. If you do it a couple more times do you see anything funky with that bottom right one or was that a one time thing? ---

[Maslow-serial (2).log](https://forums.maslowcnc.com/uploads/short-url/jpSQ8G5MFRob8vJt1RjqglksF1J.log) (3.0 KB) here is another one and the only thing that I can see and feel is shaking when the belt is being extracted. ---
