Gosh, first level seams to be wrong :-(
Well, what can I do... ;-)

For first level printing height calibration and optimization I "designed" two simple shapes.

  • Simple one is just printing complete area defined
  • Other model just place a selected number of connected measurement points to the sheet. That's much faster and should give you a good setting for z-level calibration already.

Update 31.07.2022

Attach a mini handle, to make removing the print much easier.

Print instructions

In provided OpenSCAD file (.scad), you can adjust settings to match your printer, like:

  • print dimension in X/Y
  • first layer height
  • number of measurement points to print
  • full first layer, or measurement points only
  • ...

How I used it:

  • get a rough first z level value you think usable (live adjust z)
  • make a print & check surface.
    Are there holes because you print to high?
    Is the surface quite rough/thin because you print to low?
  • adjust z level via "live adjust z...".
    Therefore you might go up/down by 0.050 mm steps for the next print.
  • continue surface evaluation and z-level adjustment till it matches your expectation.
  • I guess maybe 3 to 5 prints should do the job if your starting z-level is already in a good range.
  • In case you are curious if you complete print plate is well usable with your "measured" z-level - AND you have some hours print time left, then go and print complete first level ;-)

I used given settings for my MK3S MUU2S printer.

Happy printing! :-)

Things to improve

  • Actually it would be nice to have a label (down left corner for example).
    Therefore a dedicated place to write z-level used for this print.
  • Add maybe some more interesting shapes.
  • Add simpler shapes for (even) shorter print time.
  • Add mode to define where to place the measurement points. Currently they are oriented in the "middle" of a pattern. Edges would be interesting as well I guess...
