I find a similar problem, without solution. http://www.cnczone.com/forums/showthread.php?t=93949
----------------------- I still can not yet eliminate the delays. Connecting the Laser to the Z (A, B, C, U, V, or W) direction pin rather than the spindle does solve the problem. This delays are a headache. I just need turn the laser on and off without having these delays. ----------------------------------------------- I'm trying to do rastering with a laser. But each time the pwm changes, the movement stops for a few milliseconds. If in the next pixel changes the pwm, then there is a slight pause. Is there any way to make rastering at a constant speed, with no pauses when change the pwm?. 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. Some people suggest to connect the laser to the Z value rather than the spindle. I don't like very much this approach. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
