Ender 3 Max BLTouch Bracket and Marlin 2.0.7.2 firmware
thingiverse
Added the Marlin 2.0.7.2 firmware for the Ender 3 Max based off the Ender 3 Pro firmware but supporting the larger bed size and filament runout sensor. I used the 5 pin header on the board to connect the BLTouch but had a 3 + 2 pin bltouch cable. This made it necessary to swap some of the pins on the connectors. Please be sure to check your pin ordering matches header layout. There are two firmware files available. One is for the E3 Max with the BL touch and a standard extruder. The second is for the same machine but using the Bondtech extruder https://www.bondtech.se/product/creality-cr-10s-pro-extruder-kit/ which fits directly on the E3 MAX. Please ensure you flash your board with the correct firmware. The bondtech extruder stepper unit size is 415 vs 93 for the standard extruder.
