This MPCNC add on allows you to make your own motion controlled videos with your MPCPC.
In addition, you'll need to print a set up herringbone Gears like https://www.thingiverse.com/thing:97377
You will also need a stepper motor. I used a Short Body Nema 17 Bipolar Step Motor from Amazon.com. But a full body may fit too, with a slightly longer M8 screw.
You'll need an M8 screw, and bearings/washers for the extruder body. You don't need a large-head extruder bolt, just use the standard head adapter part included with this thingy.
If you wish you can secure the small herringbone screw with a setscrew, but I didn't. The fit is tight and the load is very small, so friction fit should be enough.
Use in conjunction with the MPCNC Motion Controller Software at www.someoldguycoding/software
