Re: [CAD_CAM_EDM_DRO] Re: BOSS5 Where to plug the Geckos???

Hi Brady,

When I did my mill I scrapped the computer cabinet completely. I then
moved the power cabinet round to the side and fitted everything in that.
You don't need the three big chokes in the bottom of the cabinet or the
great big 3 phase transformer in the middle. Believe it or not they are
the stepper power supply!. When I moved the cabiet I had to plug a
couple of holes in the base and tap one new one. The top mount fits if
you turn it upside down. There is just enough room to fit a computer in
there as well but you need to get one with a small case.

You can use the big 110V transformer in the top of your cabinet to power
the steppers/servos if you rewire it to twice your actual supply
voltage. For instance my supply is 230V so I wired the transformer for
460V. This halves the output voltage, giving 55VAC.
