Sprite Extruder CR-Touch Mount (Sermoon V1)

This is a CR-Touch mount to be used on the Sprite Extruder variant that comes with the Creality Sermoon V1. It may fit other variants of the Sprite Extruder too.

Offsets:

• X: 34mm (or -34mm, depending on firmware and extruder orientation)
• Y: 0mm
• Z: somewhere around 0.7

Print Settings:

• Walls/Perimeters: 2-4
• Infill: 10-40%
• Top/Bottom Layers: 3-5
• Layer Height: 0.2mm

Filament:

Depending on your requirements, you can print in either ABS or PLA. Tolerances should work for both. I printed it in ABS because I use it in a heated chamber that would melt PLA.

Hardware:

• 2x M3x8 mounting the mount to the extruder
• 2x M3x8 or longer for mounting the CR-Touch to the mount
• 2x M3 nuts

Important: When using this mount on the Sermoon V1, you will have ~5 mm less travel on the X-axis. You'll have to change the maximum X position from 175 mm to 170 mm in the firmware. Otherwise, the mount will collide with the left part of the X gantry.

In case of the Sermoon V1, you can route the cable alongside the flat band cable of the extruder and then up to the reverse Bowden tube. Then fix it to the reverse Bowden using some cable ties.

There is a connector for a bed probe on the PCB of the Sprite Extruder, however don't have the right cable at hand. Though, you can order them cheaply from Aliexpress. For a workaround, check the next paragraph:

For connecting the CR-Touch to the board, I used some jumper wires and empty headers ‘RSV1’ and ‘RSV3’ on the main board. One of them is for the conventional Z-endstop and can be disconnected, the other one is for the door-sensor. You have to disconnect this one as well if you want to use a CR-Touch with this printer.

I am currently using Klipper and configured it like this:

[bltouch]
sensor_pin: ^PB14
control_pin: PB15
z_offset: 0.755
x_offset: -33
y_offset: 0
speed: 5
samples: 1
sample_retract_dist: 3.5
stow_on_each_sample: False
probe_with_touch_mode: True
