Question #: 14299

Question: I forget the term for it, but are the encoders "absolute" in regards to their positioning? So if for some reason a cut is interrupted the machine can regain its position?

Current Solution

Feedback and positioning:

- Open-loop is where the computer does not have feedback, but it has the current position as per the number of pulses it has sent to the stepper motors. As long as the stepper motors are tuned so that there is a safety factor, then your machine will always be at the correct position. This scenario is common and typical for CNC machines

- Closed-loop is where the computer receives feedback from the motors and is common on very high end CNC machines. The computer sends the pulses, or signal for the motors to attempt to achieve a particular position. The servo motors will use a PID (Proportional Integral Derivative) to continue to achieve a particular position where the driver/computer will tell the motor to go back and forth (getting better as it goes) for the position. This back and forth (the PID in action) is usually imperceptible.
