ALunar M518 Prusa i3 Level Test 150 x 150 x 2 mm
thingiverse
Borrowed from elmerohueso and scaled down to 150x150mm (68% of the original) for testing bed leveling on a smaller build platform like the ALunar M518 Prusa i3 printer. Based on Jfearnside's code, I modified it to stop at each corner twice so you can check the bed level, then inserted it into his test of printing five single-layer 20mm discs. Stick the GCODE on the SD card and have a sheet of paper ready. The GCODE may stop at each corner, pausing so you can adjust the leveling knobs. Maybe push the button on the printer after testing each corner to go on to the next corner. After stopping at each corner twice, it will print several skirts around the bed, allowing you to continue adjusting height as needed while the skirts print. It will then print a disc in each corner and one in the middle to check adhesion. This procedure could probably work for any 150x150 printer using PLA.
