I am trying to do nothing more than to engrave a circle, my system and laser connect without trouble. preview is blank, I push start and the laser air control opens and closed and it says done, if i send the file to the controller (rdc6332m), it shows the file, but no preview… i swapped over to rd w…

That did it for me, thank you very much!
