🧠 Description
These shims were designed to fix filament detection issues when using the DXC2 extruder from Phaetus and DevilDesign.

The internal trigger pin inside the extruder can sometimes not fully retract and interfere with the filament detection sensor.
This may cause the printer to falsely detect filament, leading to abnormal filament detection errors and interrupted prints.

By adding these shims, the detection board is moved slightly backwards.
This creates enough clearance so the pin no longer triggers the sensor unintentionally, restoring proper detection behavior.

🖨️ Print Settings
The shims are designed in fine increments from 0.1 mm up to 1.0 mm, allowing precise adjustment.

Layer height: 0.1 mm (important for accuracy)
Infill: 100%
Material: PLA (tested), PETG or ABS also suitable

For best results, make sure your printer is well calibrated to maintain accurate dimensions.

🔧 Usage / Installation
The shim is placed between the detection board and the extruder mount, as shown in the images.

Remove the Extruder from Toolhead
Remove the mounting screws from the Detection board
Insert the shim
Reinstall the detection board
Test filament detection

You may need to try different thicknesses to find the optimal alignment for your setup.
