Attached is the xhc HB04 pendant control source code to work with KMotionCNC 4.33k, with a crude manual and the executable. We truly hope this helps someone out there. We know it helped us.
It is very crude, but it should work. The copy you see before you is a distilled version. Bugs are to be expected.
We take no responsibility for this. Use at your own risk. You have been warned.
Tom, if you wish to pursue integrating this into KMCNC, we have some ideas and would love to help.
For anyone else, I would be happy to answer any questions about this, however you mileage may vary.
