Im starting to build a 3 axis CNC with dc motors
The driving system for DC motors is made by me with a DSP procesor
I mention that i will use 2 encoders, one with 1000CPR installed on the motor, and the second 4000CPR placed on ball screw for movement correction
My question is, what will be the level of precision of this system?
