weird one, these are such good machines, been running for years without issue. After a print today I happened to notice that the Y axis has got incredibly 'stiff' and when steppers are disabled, or machine off, it takes a huge amount of force to move it. Put a little grease on the bearing rods but no different. Any ideas? should i strip and replace bearings? thanks for any suggestions
this is sorted. replaced the motor, having luckily had a set on standby for the MPCNC rig i want to make, almost identical and after a couple tries with the wire combinations, its back in action again. i only found this 'solution' out after the extruder motor also failed, it was not working properly and after checking for blockage or other feed issues i found that motor terribly resistant to turn. it is all running smoothly again now.
