It works by treating the extruder mounting bracket as a load cell, allowing it to detect the load generated by the nozzle as it touches the bed surface. You will not have to spend time cutting and extending longer wires to reach the mainboard. Issue a g29 (abl) command and wait for it to complete
We review the best sensors and probes for abl and their technologies. Connections from the printhead (most importantly abl probe) can be conveniently plugged directly into the new auxiliary board on the gantry I copied her proceedure and calulated an accuracy of 3.2% for my printer, which is better than her results for this kind of leveling sensor
If you have a different set of equipment (ie Extruder, runout detection sensor, auto bed levelling sensor, etc) then you must download all files and modify the configuration.h and configuration_adv.h files to suit your specific setup. This is a remixed breakout board cover that has an opening on the bottom for the abl sensor of the cr6 max. This short video is devoted to walking cf6.1 users through the features and functions of the abl calibration screens.
