I'll say for completeness here (having mentioned Clearpath servos in another comment) that DC clear path servos are totally fine for "semi" industrial uses. I have them on a bed mill I am restoring, and with a good ballscrew I can easily move a 300lb Z axis at 200inches/minute without torque saturation. That said, they are simple because they are limited. They give you only 3 inputs: Enable, Step, Direction. they give you one output called "High level feedback" and BOY OH BOY is it high level. it is basically only useful for basic error detection. In the software you have pretty cool tuning options - a visual oscilloscope, the RAS feature (which is really good for DIY CNC machines), and encoder resolution selection. A DMM, or especially a Delta, will give you a lot more IO to the motors, and a lot more stuff to play with. E.g. direct access to the encoder position (even if the motor is not active), many more error states, warnings, etc. and some more condition specific tuning. Last bit on clearpaths. I've been talking about the SDSK series motors. those are controlled from an external controller through pulses like stepper motors. They have other series of the same motors that interface differently. Specifically, they have some motors designed to interface with microcontrollers and have a really nice set of C libraries for doing all the basic motor control stuff. If you are building things like conveyor belt automations or material handling stuff, the clearpaths are very much an "easy button" compared to nearly every other kind of motor on the market IMO.
