Level Check Code

From Rabbi Blog

Plot path

Desc

Performs a 9 point check on bed leveling.

Save as .gcode for printer and run.

Notes

  • I have POS 1-5 saved as separate files on the SD card under POS\ for quick reference, as well as this master file for a full check.
  • Used on an Ender 3
  • I perform the test on a cold bed, if you are looking for a hot test, this is not for you
    • Gap checking with index card (5 prints since testing with index card, all good. Prior paper yielded spaghetti).
    • Cold bed, no expansion (! or ?)
    • As always: YMMV
