Hello,
While doing a 3d carve into black walnut the other day, during the rapid the stepper motors for the Y axis would skip(?). I am using fusion 360 for design and code generation and it is the version where there is basically no rapids. The rapids move at the set feed rate while cutting. Anyway as it was doing the rapid it appeared the right side stepper would not move, randomly. Some times it was just fine then a loud grating noise. The left side (as looking from the zero end) was moving and the right side not moving. I do not know if it is just a alignment issue with the stepper, or maybe something else.
A bit of history may help as well. I had a problem a while ago where the shaft broke off the Nema 23 motor and it was the same side that is now acting up. I replaced the motor but am unsure about the alignment, or how tight against the rack it should be. The Nema motor has a gear on the shaft which directly rides under the rack.
Any thoughts or insights as to why this is happening?
Thanks in advance for the help,
