Thats very cool, Thanks!

1. does the fact the the gantry moves to and fro make the focusing any harder?

2. how far can the laser be from the focusing beem to cut?

3. can you engrave with this kind of laser

4. if so, how far can you be from the focuser to engrave.

5. sorry to be a pest!

1- Yes it makes it very hard to adjust but their really is no choice for the given set-up.

2- I can cut 1/2" no problem any thicker the beam won't go all the way through. My FL is 2.5 inch.

3- Yes you can engrave no problem, I have not tried that yet.

4- as far as I know you just modulate the frequency of the beam not the FL of it.

5- No problem

Paul,

What criteria did you use choosing your drive system?
What gear ratio did you use?
Thank you,
George.
