Well, we know CNC can be made for:
And we have such motors:
Direct Drive Servo
and motors have many WATTs, and nMs too,
And there are many ranges of encoder resolution.
But how can you select a proper encoder resolution on certain application? I know the higher the best, but doesn't mean that I will use 20,000 encoder counts for each servo motor, on every application. There must be a reason why 2000, 1000, 500, 400, and 200 lines are made.
Could someone answer this question?
I hope that I can learn how to select a good servo motor, with enough torque, and enough resolution, yet affordable in its range too.
Thanks everyone again!
