Hi,
I have a modified shapeoko, and recently it started skipping steps. I changed the belts and tightened as usual. Same thing. I changed the board (oem v2.4g) since mine was 6 years old. Same thing.
I am not sure what’s up. When the power is on, I can still move the gantry on the x and y…
What could it be?
Thanks
Move the machine to the center of motion along each axis, load a probing pin, then power up and grab the tip of it and try shifting it in all directions — investigate any aspect of the machine which allows it to shift and address it.
I wonder if low voltage input from the power brick to the control board could cause that?
When you changed the belt, did you check the pulleys on the stepper motors to make sure they are secured on a flat?
Put a witness mark on it for a one second check.
Good luck
