Re: [CAD_CAM_EDM_DRO] Re: Increased power to Gecko 201's

Hi
Can you actually read the voltage increase during deceleration with a
DVM or analog VM ??
This is something I have never noticed and I have size 42 motors and the
table has a 1" thick steel plate 30" X 50" on top so there is plenty of
mass to slow down.
