Greetings, I am thinking about making a laser attachment for my CNC machine with something like this:
http://www.ebay.com/itm/80W-CO2-Laser-Tube-Power-Supply-Engraver-Cutter-New-/150552923492?pt=LH_DefaultDomain_0&hash=item230da74d64 I am tempted to go with the 130W: http://www.ebay.com/itm/130W-CO2-Laser-Tube-Power-Supply-Engraving-Cutting-/160470882820?pt=LH_DefaultDomain_0&hash=item255ccf5a04 I bet that might even be enough power for selective aluminum sintering. It states that those power supplies can be controlled from a TTL PWM, so I assume that it will be easy to control from a standard parallel port with HAL and LinuxCNC. Is that correct? Has anyone set up a servo or stepper drive to adjust the laser's focal point? Seems easy enough, guess I am just wondering how to tie it into g-code. Before I embark on this adventure, I would appreciate any advice you might have. Thanks!
