The file 'Skew Test & Bed Level Test – For 220×220 (or Bigger) Bed Size 3D Printer Model' is (STL) file type, size is 5.9KB.

Summary

In my H-bot printer i experienced some issue like : round circles printed like oval, straight lines not perpendicular each other, and in general axes not perpendiculars.

I tried to fix this installing a CoreXY mod, but now i have to verify that problems are solved...so i decided to design this simple test.

This test can be used for 3 main purposes:

  1. Check perpendicularity of axes, measuring the diagonals. They has to have the same size;
  2. Check that the print dimensions are correct, so you can fix also the step/mm value in the firmware, if it is needed;
  3. Check that the level of the bed is good in all the bed corners and in center.

It is designed to use very little amount of plastic and printing time (about 6gr of plastic / about 2m of filament, printed in about 20-30min) This test is designed for 220x220 bed plate (or bigger), because the maximum dimension of the external square is 200x200.

The tickness of the print is 1mm, so print it with 0.2mm layer height.
