Re: [CAD_CAM_EDM_DRO] turntable

actually my psu has 2 seperate 12v outputs, but I am using one for my
xyoltex
You know of any inexpensive psu that will output 24v?

Ross thanks for the info on the encoder, I was thinking about not hooking up
the encoder, and using 2magnetic switchs (so i can tell if this table is at
home or 180 degree).. do I really even need the brake?

thanks-Lee
