I’d really appreciate any ideas as I’ve run out of options.
I’ve had my sv06 for about two years, and have never had a similar issue. When I try to use the bed levelling command, the printer heats up and runs through the first few points as normal, but when it reaches point 5 its moved to the edge of the bed and hits the far stop on the X axis. Point 5 fails, and the printer gives up.
I’ve tried auto-homing, all the other calibration steps I can think of. I’ve checked belt tensions, screw tightness and gantry squareness. I’ve tried flashing with the latest Sovol firmware, and one of the community versions of marlin too - they all produce the same results.
The probe is moving about 68mm between points, which seems too much to produce a square 5x5 grid on a 220mm bed printer. It’s almost as if the printer thinks the bed is bigger then it is, but I’m at a loss to understand what printer settings would influence that, or why a firmware flash wouldn’t clear it.
That’s roughly where it would probe point 4, it would then move further to the right to try and probe point 5, hit the gantry and grind a bit against the belt, drop down to probe the bed, find no bed present, and give up.
The only other idea I’ve had this afternoon is to find a firmware which allows for manually controlled meshing.
It has been ages since I used marlin firmware but I seem to recall they had a small non-volatile memory space where you could store override settings for things like steps/mm and mesh point locations.
