This mount replaces the existing CR-touch shell to mount the probe as close as possible to the nozzle (and saves a few grams).

Best printed in PETG or other filaments with little warping on temperature change

The probe doesn't collide with https://www.printables.com/model/356355-5015-parts-fan-mount-for-sprite-extruder-reindeer- and https://www.printables.com/model/404984-sprite-pro-cullbuck-mod, but you will need to cut a bit of the stepper mount

CR-touch disassembly

1. Print the mount now, you won't be able to print anything without the CR-touch on the printer ;)
2. Pry open the case while pushing on the clips (marked 1 on the photo) using a flat screwdriver
3. The PCB is held by:
   • 4 pegs on the PCB with some glue. I used a soldering iron on low heat (220°C) to soften the pegs and glue
   • Two clips marked 2 on the photo, that needs to be pried with a flat screwdriver or a blade.
4. Once disassembled, install it on the new mount by:
   1. sliding the PCB in the rails and lowering the small flexible clip.
   2. Once slided, raise the flexible clip to lock the PCB
   3. Push the solenoid in its slot
5. Install the new mount on the extruder. You may need to remove one of the 4 screws holding the sprite extruder to make room for the cr-touch connector

 

Marlin config

Execute the following Gcode:

M851 X28 Y0 ; set probe offset
M500 ; save config

 

Klipper config

Merge your existing config with the values below:

# New BLTouch position
[bltouch]
x_offset: 28
y_offset: 0
Places the probe at the center of the bed:
[safe_z_home]
home_xy_position: 87, 115 
Bed mesh geometry
With the BLTouch at x offset 28, the bed cannot be probed at x < 23
[bed_mesh]
mesh_min: 23, 5
mesh_max: 225, 225
probe_count: 6
