the increase in rapid speed to 300 IPM is the biggest benefit of servo’s. not relying on mechanical limit switches is also nice, servo’s hold home position powering down and back up much closer, I’d say in the .0002 range from what I’ve seen.. and instead of loosing steps and continuing to cut the part incorrectly, servo’s throw an error and stop. I have pushed too hard a few times and stalled a servo and had to reset after adjusting.
Overall it’s nice to have the features servo‘s have but not sure it is worth the $2k upgrade, steppers worked well too, though I am glad I did it, I learned a lot and that is mainly what I enjoy about CNC the most.
