I am brand new to the site, and I know I will get some good answers here.
I have an Airco servo graph plate burner 5 x 12 feet (Pictures attached). My unit has an electric eye, you can draw a picture and the eye will follow it. I have a gas torch and a plasma torch mounted on it. The width has a rack and pinion, and the length has a metal bar and a tension wheel runs against that.
I would guess that the Cross Assembly made of the square and rectangle tubing weighs around 200 pounds.
I don't plan on cutting real close tolerances, mainly art and some fabrication pieces. I would still like to keep the electric eye for some applications.
If I add a rack and pinion to the length will that be fine?
I see some use screws, slides, ball, belts, etc.
What kind of motor should I use?
A servo or stepper motor?
