Code and Instructions for adapting an "SNES Classic mini" gamepad for use as a CNC Jog Controller with fabulously free & useful Universal GCode Sender. I learned everything in the code from trial & error, plus reading through this file. After doing all that, I discovered that there's a library that also handles this stuff living written by another fine specimen of Kevinhood with the handle MadHephaestus. I'll probably go steal some stuff from that library before I'm done here.

Good luck! Feel free to open issues.

* Bumper Speed Adjustment: For X/Y Directions, press the DPad. Hold one bumper (either one) to go the "medium" distance (10x normal). Hold both bumpers to go the "large" distance (100x normal). For the Z direction, use the A/B buttons for up/down. Same as the DPad, hold one bumper (either one) for 'medium' and both for 'large' distance.

Note: I'm probably going to change the controller bindings a bit, as I'd like them to be a bit more "consistent".

I've been running a CNC Machine for several years now. Unfortunately, it's kind of clunky to control using a mouse or keyboard. There are a variety of devices one can purchase called "Jog Controllers" that give you a dedicated device for moving around the CNC spindle. The trouble is, they're expensive, and I have no idea if they'd work with my little hobbyist setup, using the reasonably good UGS G-Code sender/CNC control software.

• Switch to using XY 10 and Z 1 commands instead of remembering current values (which may change)
• Make the big switch into a declarative state machine of some kind
• Maybe break the code into better pieces to enable support for other controllers/protocols?

• Pictures
• General improvement

• Make a little 3D printed case?
