If you are talking about jogging manually it is not possible to jog along a curve as the X and Y feed rates are changing continuously. Even if the machine could do it, you would need an analog joystick with two axis to do that.

Hi,
you could issue MDI codes but you'll have to work out the Gcode manually.

Hi,
have you experimented with G3 and G3? I've found that the centre format command style to be useful assuming you know where the centre of the
arc is supposed to be.
