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

https://github.com/bigtreetech/MicroProbe/blob/master/MicroProbe%20V2%20User%20Manual_20240304.pdf

^!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.

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!!

@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:

dir_pin: PC5
enable_pin: !PB1
microsteps: 16
rotation_distance: 8
endstop_pin: probe:z_virtual_endstop

Hi. When trying again, the probe does not lower

@Edikxp What control board is your printer using?

I also cannot seem to get my probe to lower. It will work fine to do a bed mesh however it does does not stow the probe once down. the macro to deploy the probe works, only if it has not been deployed yet, but the one to retract does not. on start up it does complete the 3 movements up and down. I am using a BTT Pico.

Edit: it does seem to time out and stow after several minutes of it being up

Your config doesn't include the PROBE_DEPLOY and PROBE_RETRACT macros, so maybe check those are are equivalent to the PROBE_DOWN and PROBE_UP macros.

sorry, my macros are in a separate config file. I was able to get it to work by putting a 10k pulldown resistor on the servo line, Gpio 29 for the pico.
