XYZ Table design
Please view our development log here. The specifications development for a robust and scaleable machine is under development here. The prototype specifications for a torch table application will be developed on this page.
The basic design follows.
Using ball screws and linear bearings appears to be the easiest method. Present research indicates that profile guide rails are twice as cheap for the accuracy required, so this will be redesigned.
Compare this to gear drive and linear rails, which appears to be more complicated in terms of drive components.
