Loose Pulley Motor Y Failure on Selftest
I purchased a Prusa i3 MK2S kit in December 2017 and have completed the assembly but it continues to fail the selftest displaying "loose pulley motor Y". I have verified that the set screw on the shaft of the motor is on the flat part and that it is not slipping. I've loosened the belt and I've tightened the belt. My heatbed seams to move fine when I run the XYZ calibration. I have seen this question asked repeatedly but have not found a solution that fixes my printer. What else can I try?
Is this a good question?
