Hi all,
i spent last days reading and trying to learn the "misterys" of laser. I just Bought a foison chinese engraver. And i have ZERO support on it. I got a lame manual, and nothing more, so i got lots os questions... basic operations questions, that i hope anyone can help.
the machine is this. foison.net.cn/en/product3_1b.htm
it has a 80 w laser, got a software from a cia that has no site, and i believe went bankrupt, conects by USB and have a external control. the control board is from vectorsoft dsp.
my first question - after spend some hours thinking and learning from web and got all mirrors aligned - is laser so slow to cut ?! the pgm that came with it has the veloc. in mm/s. all my tests are on a cas acrylic 8 mm.
- can only CUT properly it with 4 mm/s speed. i tryed increasing by 0.2 (4.2 4.4 4.6 4.8 5 mm/s) and the acrylic did not get loose. the power is at 75%.
the chinese guy said to put the power at most in 75%. He wrote (the only email they answered) that over 75% will decrese life of laser and THAT IT WILL NOT EVEN GET STRONGER TO CUT. i thought it is strange, but in fact when i put 80%, 90% 100% of power i still only could cut at 4mm/s. Is this normal !?
second: the laser when cutting 8mm acrylic did not seens to be straight, vertical, he is inclined. I can see that it is not ok... but i dont know how to fix or align this.
third: when cutting with 45% of power.. to not loose the piece, but to do a vector engraver, if i got more than 20 mm/s it gets all aliasing; it is far from the specs of the machine i got from the website.
some photos can help understand ? my english is very poor.
thnks a lot.
