New Machine Build- 4x6 Cutting area 80/20, sourcing parts.

Well the VFD I would use has single phase input and 3 phase output.

I was curious, is there some sort of advantage to using servo's over steppers? Or vice versa? I notice a lot of the high dollar machines use servo motors instead of steppers.

Stepper motors have no closed loop feedback for position control. Missing steps will cause errors in the size of the object being cut. Servo motors have position feedback in closed loop arrangement. There are encoders available that can be added to dual shaft stepper motors to give something akin to closed loop operation. The encoder requires a different control board for operation.

Servo systems are more expensive.
