It looks like one Z-axes motor (on the left in the video) is lowering faster than the one on the right.
And then it gets to a point where it’s hitting the internal rim where the 2 uprights are joined.
I’m on v1.03

I think that what we’re actually seeing there is one side binding up. Can you try loosening the bolts that hold the stepper motors in place (but not removing them) and then lowering the sled all the way down?
That will set the positions of the stepper motors to be exactly in line with the parts above them.
Then you can tighten the bolts back up there.

OK I think that did the trick. I did the alignment & than ran it up & down 10 more times & it didn’t bind up. Thanks very much.
