Excellent example of Servo vs. Stepper vs. Feed Speeds. This is by John Dammeyer, developer of the Electronic Lead Screw Project: Electronic Lead Screw Main Page …now I did some experiments as a result of this posting

Couplers
From the ever popular CNCZone: Al_The_Man and Crevice Reamer: CR: Only 3 types of couplers offer true zero backlash connection: Solid. (which can cause problems unless PERFECTLY aligned, Helical, or Oldham. Helicals are basically solid couplers

The Dynomotion KFLOP controller can control 8 motor axis (either as 4 dual/slaved or 8 independent), complete with 8 dedicated hardware encoder channels (while any generic input could be used in theory for encoding, I

Again, from CNCZONE: Q.) What are the advantages/disadvantages between steppers and servos? A.) Step motors and servo motors service similar applications, ones where precise positioning and speed are required. The biggest difference is that steppers

There’s a lot of misconception about the subject (case in point: Excellent Reading). I also misinterpreted the information and made assumptions based on my (in)complete understanding of it. As such, here’s some excellent sources of
