Haven’t used my Shapeoko past few years. Now noticing that the left side jumps forward before the right side on Y moves.
Belts old? Stepper wearing.
Have verified that the stepper’s sprocket is not slipping.
Where to look and fix?
Things to check:
- pulley set screws
- motor wiring/connectors
- belt tension/condition
- V wheel adjustment/eccentric nut adjustment
If nothing obvious comes up, power down and remove both Y-axis belts, then power up and connect to the machine and initialize — the Z-axis should home as normal, then the X- and Y-axis motors should begin turning — the X-axis should also home as normal, while the Y-axis motors should turn until they time out — do they turn evenly and in synch?
Thanks for list, will use and reply. Ordered new belts just in case.
Didn’t find on first look but one of the sprocket set screws for the right Y had fallen out?!
Thanks again
