G-Code for Semi Automated Assisted Bed Leveling for 3d Printers

thingiverse

This Thing consists of two parts, designed for the Creality Ender line of printers but easily modified for any FDM 3d printer which is based on the Marlin Firmware. First, I have included a file containing G-code (drvax_automated_bed_leveling.gcode) which you should download to your 3d printers SD card (or USB drive if that is what your printer uses). When you select this file to print it will move your hot end (print head) to the four corners of your printer and then into the middle, pausing at each location so you can manually level your print bed. Since the G-code in this file, first heats up your print bed, then heats up your extruder, and leaves the stepper motors powered during the procedure, it provides a highly reliable way to position your printer nozzle for leveling. If you are using any Marlin based printer with a print bed of approximately 230 x 230, the provided G-code should work properly. If your printer is smaller or larger just edit the G-code file (drvax_automated_bed_leveling.gcode) to modify the leveling points. I obtained inspiration and ideas from multiple other authors including Jfearnside: https://www.thingiverse.com/thing:2874536 who further references "Weitling (https://www.thingiverse.com/weitling/about) for his original code and idea." The second file included is a 150 x 150 bed leveling test print. I have posted a video to the DrVax YouTube channel describing the G-Code and the procedure in detail. https://youtu.be/zfTm0SqIFm4
