Re: [CAD_CAM_EDM_DRO] Bridgeport CNC

Hi Dave,

I have encoders fitted on the back of the motors. Although glass scales
are theoretically more accurate you need a very complex control system
to work with them. Using them directly in the feedback loop would not
work very well. Even the tiniest amount of backlash in the system would
result in instability.
