Continuing the discussion from GrblGru 3.49 Released with raised text:
Hello I wanted to thank the author for the great work. I had a proposal to make, I was wondering if it was possible to control the directions of the manual jog and the set of some functions with a usb joystick or usb joypad. i have tested with other software that use it which makes the work a lot easier thanks
This is a good idea. I will try it as soon as I get the time.
At the moment I have only a remote control unit
thanks for the joystick I have another request.
if possible to have in 2d a ruler in mm on the xy axis and a marker of the z axis that in realtime runs through the gcode, as on 3d
Hi
can i attach handweel to GrblGru؟
Sorry for the late reply, but I was on vacation. 
No, unfortunately you can not connect a handwheel. I would also very much like one, but that must be connected in the controller software. A transfer via the USB interface would be much too slow.
