I have NEVER done this before and I have never even seen it done before, so I know nothing! I tried getting info about settings from the company and I was not very successful. I ordered the RUS001 from Laserbits and I don't even know where to begin. I know it needs to be reversed and "knocked out", not sure about proper terminology. I have for setting from another site; 100% power, 15 speed to engrave and to cut out 100% power and 20 speed. I am not even sure if there is a correct side to engrave on? Can anyone help me please and thank you!
