Ooze Free Mesh Bed Level Gcode for Prusa i3 MK2/s

thingiverse

This is my version of Gcode (Slic3r) for those who want an ooze-free mesh bed leveling experience, and also for those who struggle with live Z-adjustment of different materials. Process of the Gcode Important Note: Please make sure to clean and clear the bed before hitting PRINT. 1. The nozzle will rise to 100 mm above the bed during the preheating process. 2. The nozzle will heat up to 170 C to soften the plastic at the nozzle. 3. Mesh bed leveling begins. 4. The nozzle will rise back up to 100 mm above the bed while heating to the target print temperature. 5. The nozzle will then lower toward the bed and start printing the intro line, marking the beginning of your print. I'm not sure if raising the nozzle above the bed a second time is strictly necessary, but I found it easier for me to clean up the nozzle right before the print and it works well for me, so give this a shot and leave a comment.
