Moving joints from GCODE

Is there a way to move directly the joints when running a gcode program in a machine with non-trivial kins?
The problem is that when I want the machine to go to a point at the fastest speed possible (G0) it still interpolates a straight line, instead of just moving each joint to its final position at it's max speed. is this a bug?

I think it is probably a feature. You _probably_ want to be able to predict the path that a G0 move will take.
I also think that the move will finish in exactly the same time anyway (though that is without any analysis)

You might want to read up on the behavior of G0 here .

Sorry, so it´s ok wit h G0 to do a straight move. Is there a way to do the move with the joints independently?

Sure just program each joint on a separate line.
