Скачать или смотреть Building a pendant jog motion controller for my CNC machine which runs on Grbl.

Early but promising development. The jog control is there but needs tuning. The feed rates on the motion are purposely slow for now to keep the motion safe until I am confident that the bugs have been worked out.

The motion commands are implemented and demonstrated in two ways:

1- Jog control. The speed of the wheel rotation drives the size of the movement step and that is what is shown in this video when the jog mode is selected. I am investigating an alternate approach where the speed of wheel rotation drives the speed (feed rate) of the motion commands in Grbl.

2- Fixed step size. One selector switch sets a scale value (0.1X, 1X,10X or 100X) and every step of the encoder is multiplied by this value. This mode is what most g code senders use when clicking on their jogging arrows. An advantage of this method is that it is more consistent and repeatable. It is also easier to implement and I am actually quite happy with it.

I plan to share the code in case others are interested in it and I will add the link here. However I need to tidy it up a bit so that it is a useful reference and not a burden.
