This printer configuration file will work with either the 4.2.2 or the 4.2.7 board with a pro or non pro ender 3 from Creality. I have both and this works on each. I run a quick bed level, more to just get the axis' home, then start the tuning process, then I dial in the bed after its tuned since this take time. I suggest you tune your printer as well. I start with a PID tune on the bed then the hotend. Continuing with e-steps (rotational distance in Klipper) and then flow. I hope this saves you time. DWTC
