I have a 60W Omtech that doesn’t like to cut through 3mm at a decent speed, let alone 6mm. Most of the project I’d like to make require 6mm. How much of a difference would upgrading my lens to the 101 mm Cloudray CO2 Laser USA CVD ZnSe Meniscus Focus Lens help with that? Do I need to purchase anything else to use the lens or can I simply swap out my new one for the old one? I know about upgrading my air assist but I just don’t have the funds.
Slower speed and stronger air assist. If it has been difficult to cut 3mm, clean your lens and check the laser tube.
I cut 6mm acrylic with my 40W tube, you should slice through 6mm mdf with that machine no problem…
- properly working tube
- clean and aligned optics
- proper focus
If you have these three it will work as expected, so one or more of them is questionable.
@lucas is correct in that a good alignment is probably the answer…
A good alignment should include a test at mirror 1 (m1) to check the machines TEM state or resonance.
If it is not TEM0 state, you tube has gone south…
