Should be expected, when probing bed, z axis moves up and down quickly which caused binding.
If you were able to only print in vase mode on a perfectly flat surface, you can get away with no binding issues. But to allow proper bed probing and z motion (z-hop, etc.), a second belt was added to support the opposite side of the bed.
- 5mm stainless steel rod (mcmaster)
- 625 bearing
- 6mm belt (ran out of space for 10mm belt)
- printed belt attachment block + 2 M5 bolt
