I am working on a new Ender 6 CoreXY printer, to which I've made the common BLTouch modification. This uses factory-provided wiring and a mount point inside the fan shroud. Unfortunately, I have a consistent 0.05-0.07 mm bias between the ends of the X axis, which effectively nullifies any autoleveling done with the probe. There is a very clear difference in first layer quality and it gradually worsens along the +X direction, so the nozzle isn't shifting up by a comparable amount the probe moves down as I might expect if the toolhead was pivoting on its Y axis.
Throughout trying to trace this, I've isolated any vibration or cable drag by removing all hotend and fan wiring, leaving only the probe, bare heatblock, and X+ endstop .This had no effect. I've also tightened up the rollers on the X axis and tried a different probe, as well. With the tight fit preventing me from wobbling the toolhead rotationally it's not clear to me what else could be systematically shifting the probe trigger point from left to right but not correspondingly move the nozzle along with it. What else could affect this? Thanks.
