I have a concern.
My encoder has 2000 counts per revolution.
and my manual says this.
position feedback for the upper and lower Z axes is provided by their respective Z position encoders. these encoder send pulse signals to the control as their shafts are turned by Z motors.
One revolution of a Z motor and ballsrew equal one revolution of its encoder shaft, and equal 8mm of carriage travel in Z axis. During a single revolution of a encoder shaft.
my ENCODER_SCALE serious:
2000 count / rev x 1vuelta/8mm = 250cunt/mm
This would be correct?
thanks.

Yes. However, it is possible that the encoders might be 2000 lines, and that would be 8000 counts so if you see an unexepcted 4x scaling error, that is why.
