Binding at the end of travel should be an adjustment matter then. Did you use the procedure of floating the idler bearing block and motor into place?

Just read through that section of the instructions again and will give that a try. Thanks.

Still having issues. Getting inconsistent results on some cuts. Discovered something new today. Still getting a dragging effect on the Y axis. Noticed today that the screw head for the anti-backlash nut is digging into the extrusion. May just have to tear the whole thing down and try to figure out what I screwed up. Probably won't get to that for a week or so. Attachments:

I think that is the main problem then. That's a significant dig in. Check out page 20 of the assembly instructions. There's a small amount of clearance between the slot and the head of that button cap screw. Depending on the clock direction of the v wheels it either is comfortably in the slot of scraping. Take a look at that section please.

Ok. Thanks for providing that. Monday we will priority out electronics. There’s nothing else I could imagine it being. I had become convinced it was mechanical. I think there was some of that but it looks like there is some power interruption to that motor.

Thanks. Hopefully that will resolve it.

Tried an experiment. Swapped the connections for the left and right Y motors. The left motor still lets me turn it manually when power is on. Wondering if the issue might be the motor rather than the electronics.

Received new boards and motor today. Installed new boards and stepper drivers. Didn't make too much difference and I could still spin the left Y motor by hand while under power. Swapped out motor and everything looks good now. Will try some test cuts later to make sure.
Thanks Derek for all the support!

Glad that worked out well. Thanks for walking through that process with us. I know you've made great things with the M3 so I really am eager to see what you churn out with the CK. Sorry for the trouble! For what it's worth, this is the first motor I've ever seen bad. Hopefully the last...
