Making a plasma cutter table. Bit skeletal at the moment but slowly coming together.
1 MOD racks and steppers for the X and Y, 3mm screw and DC motor for the Z.
Hope to get it moving soon, see how she goes, run her in for a bit. Problems with the pinch roller on the Y axis which stops the torch tilting, think it needs a fatter spring. Needs attention to the fixed rollers on the Z, something isn't quite parralel there :D
Haven't done the X axis guide rail yet, will post updates...
