Hi
I have an 80w chinese laser
I am trying to engrave a drawing but its not doing it properly, on vertical lines it goes deep but doing letters its very weak and letters turn out much lighter
I also tried to vector engrave a drawing in cutting mode with low power and it was going well until it had to draw a circle which it did but cut the wood through
I think it might be the laser going but it seems to be cutting more or less the same, both ply or acryllic, 3-4mm only when engraving is different and now I need much more power to engrave used to engrave at 600mmsec 14-15% and now I'm doing 38% as it can be seen on video
This happened between jobs I was engraving a small part 3 or 4 minutes work, and when I repeated the job it barely engraved, do laser tubes go out or start going out this way ?
I enclose link of video, can someone take a look and maybe help https://www.dropbox.com/s/d7pmde6e1b...00300.MTS?dl=0
Not really looking forward to buy another laser straight away which was the recommendation of gweike where I brought the machine
machine is year old and hasn't had much use its been used but not heavily, at all, temp has always been under 25º
Really appreciate some help.
