Re: [CAD_CAM_EDM_DRO] Power Supply Box's

Jarrett,
Biggest problem for me I was using an old plasma w/
old technology - working beautiful now with new
machine.

I've got my enclosure stationary and fixed - with
separate alum boards pressed and isolated from each
other using nylon bolts. A 5'x10' Table - what
exactly are you building that you need a mobile
enclosure - I would think you might be better off w/
pendant with wiring becoming long and possible
connection problems?

Darren Lucke (nope, could use 4' drift in my driveway
- only put 50 miles on sled last year - where ya at?)
