Hey guys, I'm having an issue on my 2.4r2 350mm. It has been printing great for about 454 hours but now I am constantly getting "Probe samples exceed samples_tolerance".
So I built a new klicky probe and replaced the microswitches in both the Z-endstop and the klicky-NG (New switches are: D2FC-F-7N). At first this seemed to resolve the issue, the first 3-4 prints ran with noticeably better tolerances on both QGL and Auto-Z calibration, and without errors. Then last night it randomly began throwing the same error as before, and now it won't even finish the QGL process because it's cancelling due to the probe readings being so far out of tolerance. If it does make it past QGL then it fails on the Auto-Z calibration.
I have checked the Z belts, they are sufficiently tight and as equal in tension as I can get them. I have also snugged the bed screws. This has me scratching my head, I can't think of what to check next... Anyone here had an issue like this before?
