Hi! i have tried your plugin and it work but this happen:
1) start M3
2) load gcode
3) push reset button
4) push start button...
The system is blocked as shown in attached figure, with Dwell led that blink, is it normal?
i push stop, push reset twice, and start... the application start.
This is the same thing is happening in my plugin ... but in my, position and the line of gcode still are not updated.
thanks
