MKS SERVO42C Closed-Loop Stepper: Tests vs Servo with Field-Oriented Control and TMC2209 Open-Loop

Video Description

The MKS SERVO42C closed-loop stepper system can be found at a reasonable price, but how does it stack up against open-loop steppers we know and love, and how does it perform compared against a servo system? In this video, we put all three motion systems to the test. We look at the power and thermal performance, and run stress tests to find the maximum accelerations and speeds in a linear motion setup.
