Re: [CAD_CAM_EDM_DRO] Power Supply Box's

Darren, well come on up! :-) I'm almost straight north of you, just over the boarder by 20-30 miles... [ About 4-5 hrs from you probably] You could put 50 miles on your self in 1 hour right now... just point it in any direction and pin it.. :-)

My Machine is 20' x 10' w/ a 4' Z axis. We've got a mobile control box on our lathe at work and man is that sweet, you can pull it out of the way when loading something into the machine or move way down to the other end when setting the live center on something long.. it has a pendant as well but the combination of the two options sure makes it nice.
