Have you ever wanted to redo your first-layer calibration, but you have a 0.6mm nozzle installed (or some other variant configuration)?
The STL file below allows you to slice a first-layer test print for your printer's particular configuration.
Test print operation:
The test print begins with a large, hallow outline performing right-angle changes, curved changes, and skewed changes, plus a nozzle jump. It will print 2-5 perimeters (depending on nozzle size) for the outline.
After the outline completes, 3 test shapes will be printed inside of the outline:
It will print another 1 to 3 layers on top, depending on slicer settings (max height is 0.65mm).
NOTE: while two GCODE examples are provided in the files section as examples, it is recommended that you slice the STL file for your own printer's settings per the instructions below.
Pull the STL file into PrusaSlicer, and slice the model according to your printer's configuration, including:
NOTE: it is recommended to slice the model withOUT a skirt [set Skirt: Loops (minimum) to "0"], and also do NOT select Brim or Raft options (these are off by default).
On your printer, preheat for the appropriate filament, select the steel sheet setting you want to configure, and then begin printing the GCODE sliced from the model above.
After printer has preheated and performed bed-level test, push and hold the selector to activate the first-layer calibration setting, and fine-tune the Z-offset calibration per the Prusa Printer manual.
