I built a portable 3(8) x 4 Plasma Table. By portable I mean one person can knock it down and move it and set it back up and nothing is heavier than the plasma cutter...

Oh, and what I mean by 3(8) x 4 is I can load a 4 x 8 sheet into the machine but my cutting area is only 36" x 50". After cutting as needed I slide the sheet out...

Control = EMC2
Transformer = Antek
Drives = Gecko 203v's
Steppers = Automation Direct
BOB = CNC4PC
Fire = Hypertherm 1250

This first picture is of the inside of the Y Drive showing the limit/home switch.
The second picture is of the Y Drive assembly on the Frame World rail. Limit/home switch not yet installed in second picture.

Not sure if this is interesting to anyone but here is a couple more pictures showing the electrical cabinet.

John keep us posted on how those linear slides work out for you. They look like the 80/20 type in the pictures. I thought seriously about using those but the folks at 80/20 didn't seem to think they would work well in a plasma application because of possible racking. It will be interesting to see how they work out for you.

They work fine, the machine is finished and with the dual belt drive and a jackshaft between the two sides of the Y axis no racking is possible. You do have to wipe them clean from time to time and I spray some teflon spray on them so they slide smooth. I started out with 80/20 but switched to Frameworld. The Frameworld slides are built up so you can adjust the play easier and take them apart easier.

Big john, your machine looks VERY NICE! Mine wont be so pretty, but I hope it works good. Thanks for your help in my project and decisions as well, I really appreciate it as these projects can be very overwhelming for a newbie cnc builder like me.
