OAK linear encoder

[jannickz]

Yes, using linear encoders to improve precision and accuracy in a CNC machine is a common practice. Linear encoders provide real-time feedback on the actual position of the machine axes, allowing the CNC controller to make adjustments to the servo commands and airframe bearings maintain precise positioning.

In a closed-loop control system, the CNC controller continuously monitors the position feedback from the linear encoders and compares it to the desired position commands. If there is a difference, the controller adjusts the servo commands to drive the machine axes closer to the desired position. This process helps to minimize errors and maintain high precision at https://www.tradebearings.com/roller-bearings-catalogue.html.

My experience and scale
I am the very first who use linear scale in centroid

I used Hedienhein analog scale with digital converter exe601 for Large scale machine bigger then 2000mm.

Above m.c has Fagor Linear scale wit .001mm resolution and ruin Velocity Mode .
Recently i use
Fagor TTL type
