bed levelling calibration parametric concentric squares

thingiverse

This is a bed levelling helper, you can customise the bed size, line width and spacing using the scad file. As the lines are tightly packed it gives you more opportunities to make adjustments and see the result as it prints. You can also use it to asses how flat your print bed actually is over the entire surface. Using a bed levelling print seems to give better results than using a shim on its own (you should do that before attempting the print anyway). Print Settings Rafts: No Supports: No Notes: Cura sometimes seems to have a problem printing walls with a thickness of double the nozzle size. Check the single layer view for layer 1 as it may be missing some parts of the print entirely. Slic3r seems to handle this better. You can adjust the line width and spacing using the scad file. You may also be able to get it to print in cura by temporarily adjusting your nozzle size although I'm not sure what other side effects this may have. The 150mm print object has 0.8mm line width and 1.2mm spacing. The 180mm print object has 1mm line width and 1mm spacing. Make sure your printer is centred correctly etc otherwise this could print off the edge.
