NB: We use bltouch as Z endstop (removed mechanical endstop).
NB2: Bigtreetech Manta EZ3D uses 3.3V logic, not 5V. Do not apply 5V to IO.
Some help: https://all3dp.com/2/klipper-bltouch-simply-explained/ And more: https://all3dp.com/2/klipper-z-offset-simply-explained/
- Install bltouch hardware
- Wire bltouch I/O (GND 5V CONTROL_IN GND ENDSTOP_OUT) to 5-pin bltouch-port on PCB (GND 5V PA7 GND PA6)
- Configure printer.cfg

- Do initial tests according to https://www.klipper3d.org/BLTouch.html
- Use command M119 to confirm that Z endstop is not triggered until the bltouch probe hits your nail after a G28 homing command.
- G28 to allow homing to bed
- Calibrate probe offsets according to https://www.klipper3d.org/Probe_Calibrate.html and update [bltouch] offsets and [safe_z_home] position in printer.cfg afterwards
