Anyone else have a premature Hiwin bearing failure? I haven't disassembled it yet. The printer, pre assembled, arrived a few days ago and began running thru the normal tests: Esteps, probe offset, flow calibration, temp tower, fan tower, retraction tower etc. during the retraction tower I noticed some substantial grinding in the Y axis movements. It sounds like a Hiwin rail bearing failure, I took two videos, both of manual and stepper induced Y axis movement. There is definitely a binding in movement which can be seen and heard in the video. No visible Hiwin rail scarring or signs of wear present.
Any insight from the hive mind before I tear her apart? This is my first Core XY so I thought I would ask before jumping the gun.
Side note, anyone else have a preassembled unit with a lot of electrical tape for cable management? Initial prints on the list are definitely cable management guide covers before the tape gets all sticky in a 50C+ chamber environment.
