CNC plasma cutting table

Im putting these files on here to give people insperation or ideas about creating other cnc machines with cheap parts common to reprap printers.

These are the files i used to create a small 2.5 foot by 2.5 foot cnc plasma cutting table. It uses 608zz bearings 8mm linear bearings 8mm smooth rod's and 5/16 threaded rod. The main frame is 3/4 inch square tubeing. Its belt driven (gt2 belt i believe) and the motors are nema17's. My machine runs over usb to a grbl shield and arduino uno.

The width of the machine is limited to the length of smooth rod you can find I bought 8mm smooth rod from mcmaster carr in 3 foot length's
The length of table is only limited by the 3/4 square tube length. you could easily make it 10 feet long if you wanted.
The video is of the machine test without the torch hanging off the carrage but i will be adding more video's soon.
