Re: [CAD_CAM_EDM_DRO] Servo only moving one way

Jim,

It goes from 5v to 30v never reaches 0v always carring at least 5v.
When I jog (in Y axis) right the DIR light comes on and it reads 30v then
when I jog left, the light goes out and it reads 5v.
As for the X axis it will only move one way with both key strokes.
What is 74hct541? Is it something I can fix...or will I have to have a new
board.


Robin
