MPSM Bed Leveling Utility

thingiverse

This is a quick Gcode script for bed leveling on the Monoprice Select Mini. It finds home, then steps through five positions, waiting five seconds at each spot to test clearance. The positions it steps through are: Front Left (5,5), Back Left (5,115), Back Right (115,115), Front Right (115,5), and Center (60,60). There are two versions: Utility_Bed_Leveling.gcode (five-second pause and eighty mm/s movement) and Utility_Bed_Leveling_Quick_2s.gcode (two-second pause and one hundred mm/s movement). To use this script, first make sure there's no filament on the outside of your nozzle. Then put a piece of A4 paper on the build plate. Run the print, and at each location test the fit by trying to slide the paper around. After all five positions have been done, adjust the four corners. Then run it again and repeat until you're happy with the fit. I like to adjust the fit so that there's definitely some resistance when moving the paper around but not so much that it leaves an obvious mark or gouge on the paper. But the exact fit will depend on how thick your paper is. To adapt this to other printers or configurations, change the five positions to correspond with your build volume and screw locations. For example, "G1 X5 Y5;" moves to x=5mm and y=5mm. You'll also have to check the Gcode variant that your printer runs and verify that all commands are supported. You can adjust the pause time by changing the delay in the pause commands, such as "G4 P5000; (pause 1)" which pauses for five thousand milliseconds. You can change the movement speed by adjusting the feed rate set at the beginning, like "G1 F4800 Z1;" sets the feed rate to forty-eight hundred mm/min before issuing the first move command. Happy printing!
