I'm not really sure what it'll cut yet... It's not up there with 'proper' laser cutters but I'm hopeful that it'll do at least 2mm acrylic. The speed of cut I used was quite slow, but I'm pretty sure that it'll be better when it's properly focussed and when I attach a power supply that'll actually produce enough current!
I'm just using the relay because I wanted to get something running quick and it had screw terminals. The laser I bought has a fancy constant current driver inside it, so I may not be able to PWM it very successfully anyway. I'll have to give it a try later on.
What are the tables like? Espruino does seem to do a decent job of stepper motor control...
