Size change

Postby happyhour » Wed Oct 10, 2012 4:41 pm

I'm still learning about lasers, and I would like to know if redesigning the bed size to accommodate a 2x2 cutting area causes any problems. Is there a point where the laser beam travels too far and becomes weak? If I add 12 inches to the x axis will it cause problems when the head is at full x and y travel? I would think the farther you move the mirrors apart the move vibrations are amplified also.

The machine is fine the way it is but I have to ask, because I would hate to learn later that I could have spent a couple more bucks and got a bigger machine.

The 2.x scales quite easily if you have a way to make your own skins. At the size you are talking about beam distance should not be a problem. The does not loose power with distance, but it does diverge a little. I don't see that as a problem for you.

Accuracy and alignment become issues amplify quickly with size. Be super accurate with your build and make sure it is very square.
