optimize heightmap
-
Hello,
I think my heightmap doesn't look that good. I would like to optimize it. Can you help me with this and take a look at my data/files?
Which data should I upload?Thanks

@jensus11 what kind of machine is it? You have M669 K1 in config, so a CoreXY. Moving bed, or moving gantry? It looks like the Z axis is driven from a single motor at the moment, or is it two motors on the same driver? Does it have bed levelling screws?

The bed can be adjusted with screws and Z has a stepper. Leveling via a 4 point macro, which doesn't work when I check it with paper. The 2 screws in the front are ok, only at the back both screws are too far away from the nozzle. If I manually level the heightmap comes from above.
