The head seems to be jerking/jumping backward as it tries to home. The belt was very loose so tightened that according to info found here. I cleaned everything and turned it back on and it’s still making the same noise.
It didn’t hit anything but the edge of my masking caught on fire on an earlier project so I stopped the project immediately and took everything out. Cleaned it then and it kept making a “bumping” noise and now won’t focus, home or scan. Any ideas on what to do next? I’m almost done with my Christmas orders - ha!
