K40 Did not cut 2mm Plywood
Posted: Tue Aug 09, 2016 7:58 am
Hello,
I`m a newbie in Lasercutting. I use a Chinese K40 III machine, with new Gold Mirrors from Marco an a new Lens and Lens Holder. The Machine is setted up an I get on the Focus from 63,5 mm a fine dot. I have a water chiller an Air support, too.
I can cut Paper with a very fine line and I can cut Plexi Glass in 2 or 3 cuts. But if I try to cut Playwood from 2mm it burns and I get a cut from about one millimeter. If I do this with 5mm cutting speed it burns heavy on the Plywood, if I cut with 10mm cutting speed I get a better cut without heavy burning but not so deep. Cutting with 90 percent LaserPower an 10mm speed I can not cut the 2mm Plywood in two cut sessions.
Can anyone help me?????
Oh, and I use the original cutting software with Corel.
I have ordered from Lightobjects the upgrade kit last year, but I am still afraid to upgrade. I use only a student License and Im not able if Laser Cad works with them.
I know that it is not a professional Laser, but I expect only a machine that cuts 2 and 3 mm Plywood for building a plane.
Hope someone has an idea!
Thanks for that
Thomas
