Instaling on Sovol SV08

[witorwitor]

Could we get some instructions on how to wire this to the toolhead on Sovol SV08?

Also for those who run mainline Klipper it would be nice to have some detiles on how to set the config files to make this probe work with SV08

Hi :)
I'm just passing by.

Personally, I have a microprobe on an SV08 that's been working for a year.

For this, I used a pull-up resistor like the one in the diagram below, but I connected it to the 3.3V debug port of the STM32.
The UART port is 5V, even though the STM32 is tolerant, this is not recommended.

I'm using the 24V from the BL Touch port for a motherboard fan (pins 1 and 2).

[gcode_macro Probe_Deploy]
gcode:
SET_PIN PIN=probe_enable VALUE=1

[gcode_macro Probe_Stow]
gcode:
SET_PIN PIN=probe_enable VALUE=0

[output_pin probe_enable]
pin: extra_mcu:PB7 # Change this to the Servo/control pin number for your board.
value: 0

[probe]
pin: !extra_mcu:PB6 # Change this to the Probe/Z- pin number for your board. Remove the ! for V1 probes.
deactivate_on_each_sample: False
x_offset: -16.50 # Change the probe offsets to meet your machine requirements.
y_offset: 10.80
z_offset: 1.150
speed: 5.0
samples: 3
#sample_retract_dist: 2.0en in printer.cfg, add this line at the top:

samples_tolerance: 0.02
samples_tolerance_retries: 3
activate_gcode:
Probe_Deploy
G4 P500
# allow time for probe to deploy before homing Z
deactivate_gcode:
Probe_Stow

Here's also the setup I use on my Klipper.

Pay attention to the offset, as you can see in the photo, I decapped the MicroProbe to put it in a custom case that also integrates a filament cutter, a filament loading sensor, and a Bambu Lab X1C hotend.

Please note, I'm doing more or less everything from memory, I'll let you check it first.
