Bed leveling and first layer calibration
Hi everyone,
I am having some trouble with bed levelling with my mk3s+ after re-aligning the Y-axis rods. When setting my Z-offset, it seems like the middle of the bed is far lower than the edges as seen in the top image below. However, the bed level visualizer reports the centre being ~0.3mm higher than the edges/corners (see bottom image). So when I have the offset set to the correct height for the middle, the nozzle will dig into the sheet during the purge line.
So far I have done XYZ-calibration again, self-test, Z-calibration, first layer cal., but nothing changes anything.
I doubt that bed level correction will solve anything since it only tilts a plane, which would only move the "dip"/"hill" around.
I have ordered high temp silicone tubing to do the silicone bed leveling mod, but it would be nice to see if there is any other solution to the problem.
So that's my question: can I solve this in any way?
Thanks in advance!
Redo your bed tension
From that tension map, it looks like you tightened concentrically from outside in.
Either way, in settings, enable 7x7 bed mesh leveling to get compensation for the bed curve automatically.
Redid the bed tension
I am already doing 7x7 mesh bed levelling, but the nozzle still digs into the sides when the centre is good.
Following the guide from prusa help desk, I redid the bed tension, which after a 7x7 mesh measurement resulted in the image below.. I can't see much improvement 🙁
