Gantry Rail binding on Y axis
My Core Ones Y axis is binding about 2/3 of the way on rearward travel. When building the Core XY system the movement was smooth and was not binding. My printer failed its initial Y axis self test, at this point I am unsure if the root is the issue is the rails themselves, the gantry being misaligned or the core XY plate being misaligned from part 8 final assembly. Any ideas?

After dissasembly, I discovered the filament sensor cable despite bing securely tied down was grabed by the right side gantry carrier. Also fixed the y axis calibration failure by adding a single M3 washer (0.5mm thick) behind each of the three screws holding the gantry to the right side and adjusting the belt tension in unison.

Please check the cable to the filament sensor (right side panel). On my build, it got stuck in its cable tie when I installed the right side panel. So the cable was bulging inward, and got in the way of the linear bearing which rides on the right Y rod. Simple fix, just push the cable back through the cable tie to straighten it.

It's for sure not the cable, I ended up rewiring the love board main cable from the buddy board forward to correct the cable strain on the board side. It's for sure a mechanical bind as the axis X and Y axis moved freely during my original main cable installation. Something went wrong between part 6 and 8

I don't quite get what you are saying -- first you write that "it's for sure not" what I suggested, then you describe the very same thing as your own solution, and mark your own post as the "best answer"? Anyway, glad that your Core One works now.

Oh wow, i'm actually stupid and can't read. Thanks for the help.

This post saved me! After attaching the side panel my perfectly measured filament sensor also got in the way. Thank yo this thread the problem has been corrected. But st the end of the day this small bit could maybe be handled with a small step in the manual to check the wire after mounting the side panel.

Haha, this gave me a good scare. Thx for posting. This right side i assembled late at night, ptfe tube not in guide and cable on the inside. But now it does not collide. Phew, so much sweating in the morning.
RE: Gantry Rail binding on Y axis
Thank you so much for this post! I was having the same issue, and could not really find out why. But sure enough, the filament sensor cable was just in the way.
Straightened that out and now its running smoothly again.
