Machine has been wokring great till yesterday, started doing a print then noticed a complete layer shift. as i watched the machine would stutter and jump around when moving in the x-axis. or sometimes NOT move at all.
canceled print, unloaded, checked belt and all looked fine. connected to Cura and told to move x. it stuttered and skipped around, grinding and groaning.
so i powered down, unloaded it, and then removed the belt. removed the stepper motor. i can barely turn it bu hand it is really stiff and jerky. and when it turns it is NOT smooth at all like the other steppers.
assume it is a blown stepper ?? and will ahve to order a NEW one.
What would have caused this so that i can TRY to avoid this in the future !!
