When printing on my Ender 3 Max Neo (stock except for a PEI bed), the right side of the bed is always printing too close. I manually leveled the bed, and then I run the auto-leveling sequence. I also have it set to run auto-level before every print, and confirmed that it’s enabled using M420 S1 after the G29 in the opening gcode.
I also disabled it in one test with M420 S0 and confirmed that it is making a difference so it appears to be working, but the auto-level map seems to be incorrect every time. Any ideas?
The mesh ends up being pretty similar every time, showing that the right side of the bed is lower than the left. The concern is that, when printing after auto leveling, the nozzle is far too close on the right side, causing first layer issues, but all is well on the left. It’s almost like the printer believes that the nozzle is further from the bed than it actually is, but only on one side.
I found that the bolts holding the gantry to the base had come loose slightly, and tightened them. That seemed to help a bit, but the issue is still there. I was going to try leveling the x gantry, but I’m still trying to figure out how to do so.
