I'm not a total noob at lasers…. With that being said, I own a D1 Pro 20W, and I've had lots of fun with it.

but I stepped up my game and bought an F1 Ultra. For the life of me, I cannot seem to figure out how to color engrave on stainless steel.  I have downloaded some test files, but all the patterns just turn out white…. (see pic) I have tried Blue Line and Fiber. 

What am I doing wrong?  I can control the embossing without a problem; I just can't print in color.

any suggestions would be greatly appreciated...   TY.
