I wish my solution was as simple... The Y asix moves erratically, as if it is resisiting impulses to move. (ULS M300)
The stepper is fine. I swapped it out- no difference.
The wires to the stepper are fine. I swapped them out- no differemce.
There is no drive card or board- it comes off a single motherboard with everything on it.
There's no clear software fix or cause I can find, suggesting it may be somehow electronic, in the motherboard...
Last time it did this, unplugging & replugging everythng fixed it for 6 weeks, then a second ditto, make it last 3 weeks, then back to its tricks.
Now, the undo it and do it up again makes no difference.
Best wishes,
Ian
