Frank, I’ll look at your file this evening.
Regarding your upgrade, my very own, private opinion is that you should not spend more money on diode laser.
I’ve been through it all, I’m very happy with my first diode laser, a 5.5 watt Eleksmaker, which has served me very well and has helped me get started with all the laser technology. But cutting just 3mm plywood with a diode laser is not fun, black stripes and 30 rounds to get through … It is possible that the new diode lasers which have 2 diodes, combined with some mirrors, can give something like corresponds to a real approx. 10 Watt cutting power - but sometimes it is not even possible to cut through 3 mm bad plywood with my real 35 watt CO2 laser.
My other laser has been a K40 CO2 laser which serves me excellently and has earned itself, many times. And I have even cut 16mm !! acrylic with this laser. 3-4mm BB plywood works just fine, I work with HDF and MDF on a daily basis, but mostly 3mm. Acrylic 2-6mm no problems at all.
What I want to say with that is, I paid about 300 euros for my K40, spent approx. 100 euros to “personalize” the machine, including a fine extraction. - What does a new diode laser cost? You might as well get started with a CO2 laser now and “save” some money - and - have a lot of fun.
This is not intended as a basis for discussion of what is the best laser … all lasers have their benefits for a given task.
PS. only minus about a K40, in my opinion, is its work area!
320x230mm is a bit boring, which is why I bought (today !!!) a 600x400, 60Watt machine and am looking forward as a small child to Christmas.
