What does your G-code look like? What form is your intensity information in? eg, if your G-code says things like G1 X0 S 200 G1 X20 S100 G1 X25 S150 etc then you might be able to smooth it out by relaxing the accel/decel parameters or the trajectory accuracy http://linuxcnc.org/docs/html/gcode_main.html#sub:G61,-G61.1,-G64 You could try running the servo thread faster too, I think a change to PWM value has to wait for a servo thread (every mS by default) -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
