- emc linux cnc servo quadrature encoders dc motor parallel port settings control loop PID emc linux cnc servo quadrature encoders dc motor parallel port settings control loop PID. This week i made my first foray into emc servo controls, I have used emc for a couple of years now with stepper drives (but i am still really a newbie). Basically I bought a robot arm on ebay for 10bucks and it has dc servo motors with HEDS9100 quadrature encoders. So I bought an L298 dc motor driver for 10bucks and have made initial tests to check the etch-servo control configuration works with this setup. Sorry very lame supposed "tutorial" of what I have been doing in emc linux this week, it is unscripted and unrehearsed so please excuse the mistakes and babbling. It does not really explain very much at all as most of the things i hoped to cover disappeared from my head when i turned the camera on. I don't have time to waste doing a decent job so this is all you will get for free. I may do another vid explaining emc servo PID as i understand it (i dont really understand it properly yet), and full configuration of the robot arm once I have bought some more L298 drivers. Hope this is of use to someone, but i doubt it, please don't blame me for wasting your time.

- BASIC Stamp Quadrature Encoder Demo, Part 1 Parallax Basic Stamp 2 Homework Board monitors a quad encoder, tracking a rotating disk at a surprisingly fast 615 RPM. The slowest LED (binary counter MSB) cycles 20 times in 15.6 seconds. Each full cycle is 8 revolutions, equating to 615 RPM. 16-segment encoder disk outputs 32 PPR, so the Stamp is accurately counting 328 pulses per second without missing a single pulse. Be sure to watch part 2, when the motor voltage increases from 18 to 24 volts and sets a new speed record just before the motor blows up!

Motor voltage increased from 18 to 24 volts for this test. The motor clearly self-destructs at 0:42, but the encoder still worked properly at this new maximum disk RPM. MSB LED shows 6 cycles of 8 revolutions each (48 revs total) in 3.9 seconds, or 738 RPM. Equates to 394 pulses per second, and the BS2 kept up 100%. By pure coincidence, this is the maximum calculated speed the BS2 can track.
