Hi all,
CNCJS is a very great project, thanks for it!
I'm running it on a Raspberry PI 3.
I'm trying to add a potentiomètre next to my screen link to the Rpi that can overwrite the feedrate from 0% to 100%.
I first had a look at the shortcut, but nothing seems to be linked to the grbl widget
I then looked at the information of the widget and found what I wanted to modify:
"status": { "activeState": "Idle", "mpos": { "x": "0.000", "y": "0.000", "z": "0.000", "a": "0.000", "b": "0.000", "c": "0.000" }, "wpos": { "x": "0.000", "y": "0.000", "z": "0.000", "a": "0.000", "b": "0.000", "c": "0.000" }, **"ov": [ 80, 100, 100 ],
**The ov section seems to be what i want to interface with.
Can anyone give me a clue on how to interface it or where the file is located ?
Thanks a lot
Alexis
