Folks,
Has anyone worked with cutting 1/2 basswood on a laser in 1 or 2 passes without leaving a lot of edge soot behind? The project is to cut a puzzle for carving and we have had a problem with soot accumulating in the kerf and getting over everything when carving.
Here is the recipe that we are using, and I would appreciate any suggestions or tests that someone might run.
Boss LS-1630 w/ 120w tube
- Lens: 4" - focused at 111mm from top of lens
- Speed: 5mm/s
- Power: 65% of 95% of 120w tube
- Air Assist to nozzle: 40psi
- Exhaust Ratio: 25% Top of material / 75% bottom of material.
That is the minimum that we can get through without any issues. The Air assist made a lot of difference, and I am topped out on air pressure for the system so not sure if more air would make the difference. I am looking at upgrading the hosing but right now 40psi is about the top of the existing tubing so I can't tweak much more.
Any help would be appreciated!
