QIDI X-Max 3 X-Plus 3 CR Touch Bracket
Purpose
This model is a mounting bracket designed to house a CR Touch probe on the QIDI X-Max 3 and X-Plus 3 printers. It serves as a replacement or modification housing for the probe and its associated electronics.
Practical Uses
It is used to integrate a CR Touch sensor into the printer setup. Users may need to modify the board layout or configuration settings in Klipper (printer.cfg) to accommodate the sensor. Note that the CR Touch wiring differs from a BL Touch; the extruder board typically utilizes a 2-pin plug (Red/Ground, Blue/Signal) and a 3-pin plug (Black/5V, White/Ground, Yellow/Pin control).

Printing and Assembly Guidance
Assembly requires removing the CR Touch components from the original cover. The case halves are held together by two clips on each side, and the board is held by one clip on each side. Users should be careful with the small internal wires. It is suggested to use a very small drop of epoxy on the board and probe case to secure them, ensuring the pin is aligned with the sensor's U-shape. Due to potential fitment issues with certain materials, the user reported needing to manually bore out the hole with a 13/32 drill bit and remove some material for the board to fit. While glass-filled nylon was used, PETG may provide more accurate dimensions due to less surface roughness.
