I saw Oz’s message about ESS Smoothstepper not supporting laser control. Having recently updating my hardware I can confirm that The ESS does indeed handle laser control quite well, If Lightburn can output .txt or .nc or otherwise gcode files then it should be fine. OZ have you checked out Warp9 TD’s web site for compatibility.
Also, OZ can you allow me to reset the trial version of lightburn, I downloaded it long time ago but because my machine was not complete i did not use it. Now the trial has expired.
