Ender 5 Bondtech BMG Direct Drive Print Head and MGN12H Linear Rail Conversion (e3D V6 or Stock / Microswiss Hot End)
Description
This is a remix / combination of Greg191134's Bondtech BMG print head and kmxs' Ender 5 linear rails. I've included versions for the stock Creality (or MicroSwiss) hot end or the e3D V6 hot end. Currently the only probe mount included is for the BLTouch. I plan to add additional probe mounts in the future. ### Important: You will need to reverse the x stepper motor direction. This can either be done in firmware or by swapping the wiring for x stepper motor.
