Hi everyone.
I've wanted to build a laser cutter for quite some time now but couldn't find anything that fit what I needed. So I'm currently in the process of designing my own. I've had a little read of the forum which was really helpful but I've just got a few questions..
Regarding the stepper controller, obviousley the first two channels are for the X & Y axis. Is the laser however controlled by the third. For example with different power settings for cutting/engraving?
As this is my first cutter I'm keeping things small-scale. I'm only planning to be able to cut thin card at most. What would be the minimum recomended laser power for this? Although I am aware that focusing the laser has an impact on how effective the laser is.
Whilst looking for a stepper controller I came accross this one and I was just wondering if anyone here has used one and is it any good for the price?

Are there any good USB stepper motor controllers out there which are sub £50?
Sorry for all the n00b questions but thanks for anyone who can help.
Alex.
