Rotary CNC Joystick
rdagger:
Here's my latest controller. More CNC than arcade, but the build is relevant.
severdhed:
awesome
BobA:
Wow, great CNC machine and controller. Your other projects are very impressive as well. :applaud:
What would be the main use of the human manual control (hmc) on a CNC machine?

There is quite a bit of manual positioning required (NPI). First you have to determine the X, Y & Z zeros of the material you are cutting. This is done my manually moving the bit to the edge and just above the work piece. It also necessary to be able to manually move the router out of the way when clamping/unclamping material to the tooling plate and when changing bits. Also manual control is necessary when using probes, measuring tools and performing maintenance and cleaning.
Most CNC vendors offer an MPG (manual pulse generator). This is basically a spinner with detents that can manually control 1 axis at a time. My joystick is an alternative to an MPG.
BobA:
Didn't realize there was so much manual setup for CNC but it makes sense now. Your new controller looks like a super upgrade from a MPG.
