Klipper probe config for the BIQU Microprobe (V1/V2)

biqu_microprobe.cfg

## --- BIQU Microprobe Klipper configuration ---
# Not much different from a standard probe config. The
# main difference compared to most probes is to disable
# deactivating the probe (PROBE_UP) after each sample
#
# You can either copy pasta this directly or import
# into your config.yml using [include microprobe.cfg]
#
# Note: if you are changing from a bltouch or one of its
# clones, remove/comment out the [bltouch] config!
# That also includes any auto generated config stored
# at the bottom by the PROBE_CALIBRATE command
#
# Note: the current control and sensor pin values are
# configured for the 'BTT SKR E3 mini V2' controller 
# board. You may need to update these values depending
# on your controller board model.
#
# Update (2023-10-17): This config is configured for
# the V1 microprobe. V2 users must update the 
# polarity of the sensor pin in the config to be 
# pull-down (^!) not pull up (^)

@cylon1975 I found the manual for V2 probe :) . It has a section for the Manta 8P. The configuration is quite different depending on whether you have the M8P v1.1 or the M8P v2.0.

^!PB2 Is what you want for your sensor pin (pull down configuration since you are using a Microprobe V2)
PB1 Is you control pin

@cylon1975J'ai trouvé le manuel de la sonde V2 :) . Il dispose d'une section pour le Manta 8P. La configuration est assez différente selon que vous possédez le M8P v1.1 ou le M8P v2.0.

^!PB2Est-ce que vous voulez pour la broche de votre capteur (configuration déroulante puisque vous utilisez une Microprobe V2) PB1Est-ce que vous contrôlez la broche

Hello and thank you for your quick response !! I finally succeeded by copying the script list by creating a fileMicroProbe.cfgand report this file inprinter.cfg!! Thanks again for the help !!                                                                                                                                                                 

@PaulStep61 You need to tab all the gcodes that you call.

gcode:
SET_PIN PIN=probe_enable VALUE=1

This does not work, it should rather be:

gcode:
    SET_PIN PIN=probe_enable VALUE=1

Otherwise klipper will see it as its own variable inside the config, rather than the gcode belonging to a variable.

Important note for V2 users, especially those coming from the world of Marlin. The BTT SK3 Mini E3 V3 + Marlin usually requires the use of the Z_STOP connector on the board to be connected to the probe (thus removing the need for the physical Z endstop). However, this means that the probe pin would need to be set to ^!PC2 (and not ^!PC14) for the probe not to smash on the printbed.
In brief, here are the important parts of the configuration file:

[stepper_z]
step_pin: PB0
dir_pin: PC5
enable_pin: !PB1
microsteps: 16
rotation_distance: 8
endstop_pin: probe:z_virtual_endstop
position_min: -2
#position_endstop: 0
position_max: 250

#...

# required for any probe, bltouch...Adjust the X,Y values to your printer. I use an Ender3-pro
