Stock Manual Ender 3/3pro Levelling Hack (SD Card Gcode)

thingiverse

Update: August 28, 2020 Added four repeats and tested each for PLA and PETG. My Ender 3 Pro is a stock manual levelling model, so I'm not modifying it or flashing new firmware until the warranty expires. The surprising thing about it is that Marlin has a Corner Levelling option in Configuration.h, yet Creality hasn't enabled it. What's going on?! Compared to my highly modified Tronxy P802, my Ender takes twice as long to level because I have to move it from corner to corner manually. This was driving me crazy, even though I prefer corner levelling my printers with every print. That's why I wrote this GCODE, partly for learning and partly to speed up my levelling as a stopgap until the warranty expires and I can modify it freely. It's designed specifically for Ender 3/Ender 3 Pro models but can be adapted for any printer without a manual levelling menu by modifying X and Y values. I'm sharing this completely free, like beer and speech. Feel free to use it, modify it, just remember to give credit where credit is due. Cheers!
