Ok, I’ve been living with this problem since I built my LR3 by using CA glue and shims on the Z plate ‘fingers’, but after having the shims popping off one time too many I now come to the town square for help.
My problem is that the fingers on my metal XZ plates don’t contact the faux-roller ends of the endstop levers, but land somewhere just behind it, which ultimately means the Z steppers will bottom(top?) out before they’re activated.
I’ve tried bending the levers (yeah - try getting that accurate to within .1mm with your leatherman, or having the lever not pop out), I’ve used all of the adjustment in the endstop carrier, and I ultimately landed on shims - which were The Way, except they just don’t stay in place.
What have I don’t wrong that these don’t line up? How can I make penance with the LR clergy?
By the way, those photos are take at the absolute top of travel for the Z steppers, with the endstop carrier doohickeys at their lowest point, and the switches are still 1-2mm from being triggered.
Because I’m also unable to bend spring metal within 0.1mm, I end up following “Z leveling” in LR3 docs and using M666 to config software to compensate for physical slope when left and right switches trigger at diff heights.
Yup, same switches from v1e, but I have to bend them so far that they’re basically perpendicular, or the faux roller still winds up extending past the finger and they don’t actuate.
With the shims I wound up with a fairly small Z leveling compensation (.4mm I think) but the bent attempts were off way more.
I found some switch carriers on printables with more travel in them, think I’ll give those a try today.z
