Hi HSbne
Long time reader… thanks for the interesting info / reading
I bought one of the k40 40W Chinese LC’s ($500) as a test machine to justify a larger more expensive purchase down the track.
I have it up and running, aligned the mirrors (still needs some more tweaking) and have it working.
I can cut paper and manila folder type material ok but if i try ply, mdf or acrylic it does not seem to really want to cut very deep. I have not made it through any ply in the 3/4mm range after up to 5 passes, MDF did not seem to want to work.
running up to 70% power at say 3-5mm sec etc when testing
I have watched plenty of video and some seems to cut 4-5mm ply like butter…
i am looking for advise and what trying to understand might my issues be
any help appreciated
cheers
