Hi.
Ive recently purchased a 40W laser cutter engraver from china and ive found that this forum seem to have alot of people with experince in lasers of this kind so i have a couple of questions.
Since moshisoft is a really really crappy software i didnt learn in deep how it works other then i open my DXF in corel and save as PLT file. i later use the PLT option in moshi to load it before cutting / engraving. (mostly intrested in the cutting part)
Due to crappy service from DHL they cracked my tube so i had to order a second one and change it, calibration was a pain and if i may say so myself i dont think its that good at all. Tips on how to calibrate it better an easier other then removing mirrors put scotch tape and press "test" move a little bit and repeat? Is there some way to fire a low level visible laser for calibration?
How important is it to have a center center on the focal lens?
Ive accidently dropped the focal lens when removing it and im not sure what side should be turning up or down, golden up or green up ?
Ive tried to cut into 3mm acrylic the laser eats it like it was butter, but when it comes to cutting details it fails horribly either by making it look like a melted horror show or only carve it half ways. Speed / power settings?
Ive also noted that the cut isnt straight more a little stray causing the cut not to be perfect 180 degre (probably due to bad calibration from my end)?
When i try cutting 4mm plywood it looks like a massacer i have to use high power and slow runs multiple times and i stil dont manage to get all the way, ideas ?
im using the plastic piece that came with it to align focal length to around 40mm from the cutting surface.
all help/ideas would be appreciated
