I am new to the forum and seeking information on my FS Laser Model H 40 watt co2 laser. The bed is a 12x20 bed. I have contacted Full Spectrum and was told they do not support this laser and all they have is the manual. I got this laser for a good price, thinking I would have to upgrade somewhat. Furthermore, I am looking for any information on upgrades users have done. I also would like to know has anyone added Z axis to this unit? What can the controller support? Thank you for the help
