I may have the opportunity to purchase a 2001 PRT Standard 4'x4' CNC.
How difficult and expensive would it be to expand the X-Axis to 8 feet? Obviously the main C-Channel and X axis angle iron rails would have to be changed. As for the rack gears can those added too or would I need full length rack gears? Is there anything else? Is it hard to change the computer side of things?
