Qidi X-Plus 3 Right Side Homing Stop Block

If you want to change the homing of the Qidi X-Plus 3 to use the right side (X = 280) instead of the left side (X = -11), unless you are very careful, the bed probe will crash into the Z-axis support.

(Why home to the right? Like me, you may want to add a filament cutter to the tool head, and need to keep the front-left corner excluded from regular motion.)

This model contains two blocks: one with a tab for using the existing holes on the gantry slide block, and one without (for those that can't give up the 3mm needed for the screws.) Mounting requires drilling the mounting hole(s) with a 2.8mm drill bit, The side screw is an M3X8, and the front screws are M3x6.

After installation, triple check all clearances!

You will need to change the printer.cfg file like so:

[stepper_x]
position_min: -11
position_enstop: 280
position_max: 280
homing_positive_dir: True

If you are using the version with the tab and screws on the front face, I strongly recommend you switch to homing the Y axis at the back corners. You will need my other homing mod.

Save and restart Klipper, and you are ready to go.

CAD for these models is available on Onshape, here.

Note: I printed mine with 4 walls and 20% grid infill, just to make it nice and stiff.
