Hello,

I am about to purchase linear encoders for the mill.

They will be connected to a DRO for now, but in the (not so distant) future the mill will ve converted to CNC and the linear encoders will be used for closed loop control.

I have the option to purchase encoders with 5um resolution or for a small price increase with 1um resolution.

The end goal is offcourse the CNC conversion. Will the higher resolution feedback encoders improove the overall closed loop CNC accuracy? Or will they cause more trouble than added value? I am thinking here at motor hunting and the likes. I will be using servos to drive all axis.

Thank you,
Andrei
