I saw that paint spray can holder and said I needed that. Did up my drawing, transferred the gcode to the Shapeoko, cut and assembled it.
But … Paint cans wouldn’t fit. My round holes were really ovals. Checked the drawing - it was OK, tried some other feeds and speeds, no difference. Reloaded the setting to the machine, no difference.
So what would the forum tell me to do next - check the set screws on the stepper motors. Well the left Y motor had one missing and the other was not tightened on the flat spot! - problem fixed.
So remember when having an issue make sure you don’t have a screw loose! lol
