M4.1 belt shortened, can I still calibrate?

I’m new to maslow. I cut one of my belts in half after it was damaged. I ordered a replacement but in the meantime can i still calibrate and cut if one belt length shorter? I also have the issue where when i click calibrate it unspools the belts completely and goes as far as to wind them tight the opposite way (flat side facing out). I will keep searching on the forums for answers, but if anyone could give advice because I’m very uncertain how to troubleshoot.

Just got my full 4.1 kit a couple days ago. unfortunately my belt got jammed while unspooling during calibration. I believe I deformed it further trying to pull it out. so I disassembled it, cut the belt at damaged area and reassembled.
I’m having trouble calibrating it. I think it is stuck at step 4 to six. idk how to know if the calibration is complete or i should retry

Yes, as long as the belt will reach the anchor from the far corner of your
workpiece, it doesn’t matter how much more is on the spool

I’m having trouble calibrating it. I think it is stuck at step 4 to six. idk how to know if the calibration is complete or i should retry

I would power cycle and retry.

ended up downloading a new yaml and updating that. after that ive been able to calibrate. i also switched to vertical orientation which helped with not having as much slack during failed calibrations. still when i was figuring stuff out i managed to break my belts multiple times. I’ll have to order a 2nd replacement belt to do full sized cuts
