Hey guys, my machine has done this grinding noise occasionally, but a reset clears it right up. It’s not physical grinding, it’s like the steppers have no power and simply skip steps instead of moving the gantry. Since Monday, nothing I do will stop this. It’s very strange, as if I move X or Y independently, it makes no noise. If I move the 2 in tandem, all sorts of steps are lost on both X and Y. No pulleys or belts are slipping, and if I try to stop either axis with my hand, I cannot. It’s strong. I checked both the 24 and 48v power supplies, and there’s not so much as a dip when the motors move. It’s only when the file starts, or you move 2 axis at once. It immediately skips steps. Any idea?? Thanks so much for any input you can give.
I’d post a video, but the dang forum doesn’t seem to have the option to do so, without first uploading it to YouTube or something like that. So I guess I’ll go try to do that and come back and do a follow up post.
