RE: Failed Y-calibration of a new CoreOne
I found this post after failing the initial Y-Axis calibration. I re-did the belt tension. I gave some "persuasion" to the bar that the extruder sits on (as the instructions are now saying). I looked at gaps and did everything I could think of. Then... out of chance... I happened to notice that the filament sensor cable was protruding away from the right wall a bit. I pulled the slack on that to the rear (straightening the cable). No more failed calibration.

Yes, besides a bent gantry probably the second most common is the filament sensor cable interfering with the y-axis movement.

Yes, that's a classic trap which has been mentioned here quite often. I like to think that I was the first to fall for it. 😉

Yeah - good observation. I did the kit build of my Core One and had the same issue early on - Y axis gantry interference with the filament sensor cable.
