I apologize for the confusion. Rookie mistake, i not only had the cover switch wired wrong but also had a few wires mixed up on the interface panel. So my laser is firing, and firing from mach! I have done a few test runs, both through cut2d and the engraving plugin for mach. I havent done anything too big yet because i wanted to get my exhaust and the air assist in place. Now that i have that set, i have a couple questions. The focusing mirror i ordered from light object is 18mm, I was under the impression then that the material must be 18mm away from the mirror in order to be focused. Slight problem there. My limit switch assembly on the gantry hits the bed before 18mm is reached. The air assist nozzle that i ordered from bart seems built for a 50mm lens. While i do get a nice looking cut with the air assist on, at max power there is an obvious etch, but no cut through. Is this something to be concerned about? I am only using 3/32" basswood to test so if im thinking correctly, that should cut through right? im running my cut at 30 ipm and max power. Does it need to go slower? at this point is it just about testing different speeds and power to get it right or is there some change that i need to make?
Another point. The round piece that goes around the threaded rod and connects the belt for the z axis motor keeps slipping. The screw that holds it in place is tightened but eventually loosens. has anyone else run into this problem. if so any solutions?
