Summary

Hi!
Here is the config I made from scratch for my Anycubic Mega Zero 2.0.
Mine has this upgrades on it, so config is made for this exact config:

• BTT Skr Mini MZ board
• BLTouch
• BTT Power off Relay 1.2 ( which is controlled by GPIO pin 17)
• And I have Hero Me Gen 5 gantry so change the X and Y offsets in [bltouch] block to add yours

The min and max positions are set for my exact config with belt tensionners etc, so perhaps you'll need to modifiy them by 1 or 2mm. At first power on and test, always keep finger on power off switch as always recommended.

The safe Z Home is set to be with probe dead center with my offset, so if in your case it's different, just change home_xy_position values

Same for The Screws tilt adjust ( equivalent of bed tramming in marlin) that is set to position the BLTouch exactly on bed screws position, with the offset of my hero me gantry, it can be different in you case, just adjust each points, it's easy in the config.

For the BTT Relay 1.2 you need to plug a single wire between GPIO 17 pin and reset pin on the relay, and add lines in moonraker.conf, here they are:
[power printer]
type: gpio
pin: gpio17
off_when_shutdown: True
initial_state: off
locked_while_printing: True
restart_klipper_when_powered: True
restart_delay: 1
timer: 5

I had set it to create a switch in the power options, when you activate it it will also restart the firmware after 1 seconds and come back to idle to avoid keeping GPIO 17 5V output, and avoid blocking the relay on power on position. Just adding the M81 in the end print block end in the config works perfectly.

Config without BTT Relay is made. Can even make one without BLTouch but having klipper without a BLTouch is kind of a nonsense I think.
I just can't do one with Stock board, as I don't have it anymore.
Also will soon make a config with SKR Mini E3 V3 board.

Don't hesitate to ask me if you need some help for the config, Klipper ain't easy to understand at first look, but definitely so powerfull.

With the configs It will work perfectly but you need to do by yourself PID tuning, Pressure advance tuning, and resonance compensation, as it's specific to each printer

I just added the pressure advance stl file to have an stl in the files as it's mandatory, but use the one from Klipper documentation in case there's updates on it.
