Desktop CNC handwheel

These handwheels attach to the lead screws on a desktop router to allow easy manual adjustment of the bed position. The Y axis wheel mounts to the protruding portion of the lead screw on the front of the frame. The wheels should work on any router with 8mm lead screws and suitable mounting area. As printed on my Creality CR-10S it is a perfect friction fit, just press it over the lead screw.

The X axis wheel is mounted by loosening the lead screw and pulling it out of the coupler. Then screw the set screws in below the edge of the hole and slide the wheel over the coupler (large end first) until the set screw is at the end of the slot on the shaft. (The slot allows fine tuning of the the position.) Then loosen the set screws, insert the lead screw and tighten the set screws. The barrel of the handwheel is an exact fit within the opening of the spindle mount. If it binds, file down the edges of the set screw slots. The wheel will reduce the Y axis travel by about a 1mm.
