We have an old MiniHelix 35w laser in the shop that I am trying to get running. It engraves, it cuts but there are several issues I wanted to see if anyone had any advice on. I know virtually nothing about laser engraving and cutting, the first time I'd ever even seen one in action was when I got this one connected a couple of weeks ago. 1. CUTTING - cutting 1/8" acrylic is possible...if I set the speed to 1 (slowest) and the power to 100. Doing that means it takes 5 mintues to cut a simple 4" x 4" shape. Cutting 5mm luan plywood takes 4-6 passes to get through. 2. ENGRAVING - I'm not getting much depth. I can lightly etch acrylic giving it a decent frosted look but I was expecting to be able to slow things down and get a better depth. Even 1/32" would be nice. 3. WORKING AREA - The machine has a 12" x 24" working area....I can realistically use the top left 6" x 6" area. Once outside of that it's like the laser loses strength. I am currently running a 12" x 12" wood block....the left side is beautiful...then fades to nothingness on the right side. I checked the focus using the focus tool and used that to make sure the "deck" was level all the way across and everything seems to be perfect. I even tried shimming up the right side to see if that helped but it didn't. I've cleaned the lens and the reflector with a lint free swab wipe and purified water. The Epilog help section isn't really very helpful. Is the machine just underpowered? Out of whack? Worn out? Anyone have any ideas?
