Can anyone explain to me what is happening here?
This is an Xcarve I bought from a guy on Facebook.
May be a little hard to tell from video but one of the risers gets in a bind.
This is happening while jogging thru Easel. If I jog slow-med, it doesn’t happen. If I go faster, it happens every time. Usually, the right side binds, but the left has done it.
I have checked square. Checked distance between axis rails in front, middle, and back. Checked stepper wiring.
The only issue I have seen is the v wheels on top of the rail. As the riser runs down the rail, the tension on the wheels will vary. Sometimes 1 is tight, 2 is snug, 3&4 are loose, but a few inches later, they are all different. I swapped out the polycarbonate wheels for delrin just to see if anything changed, and it didn’t.
Only other thoughts could be the lead screws but I wouldn’t really know where to start there.
I’m not really sure what the issue is or how to correct it.
