[QUOTE="Scotts Elle, post: 9459454, member: 32566"] Thanks. No engineering background here. I was a fabricator and mechanic by trade many years ago. I am surrounded by people who are smarter than I am and are willing to answer my questions. There are lots of companies that support hobby CNC building. I got the majority of parts from ebay. My only recommendation is that you use linear bearing guides. Most home built tables use "v" bearings and the accuracy blows. I did document the build and will post some more pics when I get in front of my home computer. The main components you will need are: Break-out Board ([url=http://www.candcnc.com]candcnc Welcome Page[/url]) XP Computer with a parallel port Stepper Motors ([url=http://www.orientalmotor.com]Welcome to ORIENTAL MOTOR[/url] or ebay) rack and pinion ([url=http://www.martingear.com]Martin Gear | Gears, | Spur Gears | Sprockets | Timing Belt Pulley at Martingear.com[/url]) linear guides and pillow blocks (ebay) 24 to 36VDC, 20amp power supply ([url=http://www.mouser.com]Mouser Electronics - Electronic Component Distributor[/url] or digikey.com) various electronics like limit switches, e-stop button, power switch, cable, etc ([url=http://www.mouser.com]Mouser Electronics - Electronic Component Distributor[/url] or digikey.com) I use MACH3 ([url]www.machsupport.com[/url]) for the table control and Sheetcam ([url=http://www.sheetcam.com]SheetCam homepage[/url]) for the CAM n. I use a combination of illistrator and turboCAD to actually draw the parts and convert cardboard templates into CAD drawings. I spent about $2500 on the steel, parts, paint, computer and chemicals for the water table. Still a hell of a lot cheaper than the over priced stuff that plasma cam and torchmate push. Be prepared for a huge learning curve and allow yourself to make mistakes. [/QUOTE]
