Finally getting nearer to understanding the EMG30 stepper motors and MD25 motor driver unit. Yesterday I used two Arduino serial ports for the first time. The MD25 was using the standard 0 and 1 pins (RX and TX) so I used 10 and 11 as an additional RX and TX. This enabled me to see information coming back from the motors.
I needed to be able to do that so that I can change the speed when a certain position is reached. I want a fast speed in the middle and then an easing down at each end
