General Mach Discussion / Single Line Cut for Plates

« on: September 19, 2017, 10:23:40 AM »

Hi...Trying to figure out if there is a way to have engraver only make one cut...like a single line font...Cut each letter only once...not each side of the letter...Hope I am Making Sense.... On our Dahlgren...If we use a single line font...it only makes one stroke/pass...like down the middle...
not ...The left side if the "I"...The Right Side of the "I"....ect
