I am starting to build a laser cutting machine.
Already have the frames and all axis, now it's time to start with the Laser!
I know I know - safety first! I'm wearing eye-protective that fits the right wave-length and I'm the only one in the room.
Now to my questions - I can use a laser diode like this one:
Here's a movie I've found on Youtube -
http://www.youtube.com/watch?v=kGwleH913zs]Laser diode steel cutting.mp4 - YouTube (in the video it's a 60w diode, otherwise same connections/power supply).
1. can I use a fiber-optic cable instead of 'flying optics'? will the fiber cable withstand thousands on thousands of flexing and flexing?
if not - where can I buy optics for this wave-length?
2. how do I actually drive the laser? I have a matching power supply, I know how to connect all the axis to mach3 / emc, but - how to connect the laser?
I know it uses pwm.
3. where can one buy safety glass/plexiglass for a specific wavelength?
