Agustin, While there may be some way around the limitations of using the spindle, I have not found it. Also, the laser may be tied to any axis, but the Z axis works particularly well, and is probably the easiest to implement unless there is an irresolvable conflict with a mechanical Z.
The reason is that design (CAM) software can pretty much directly generate the necessary code without complicated posts, and when rendered through a backplot / liveplot, it is going to pretty much look like what is to be manufactured, even if not exactly to scale in Z and allowing for the fact that Z needs to be inverted. Regards, Eric If the g-code is: G1 X0 S 200 G1 X20 S100 G1 X25 S150 there is acceleration from X0, deceleration to X20, acceleration from X20, deceleration to X25, etc. So the speed is not constant and the laser kept more time in the positions X0, X20, X25, etc. This makes the laser burn more at those points. I think there is a constant speed mode, but I dont know how tu use it. ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
