The MKS SERVO42C closedloop stepper system can be found at a reasonable price, but how does it stack up against openloop 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.
