You will need to connect Step and Direction pins and +5V for each drive. See here.Will all 3 stepper drive outputs fit on JP7 (I assume they need to use one of the 16 I/O pins..)
yes. Is the enable on the drive isolated from motor power?Is it normal to connect the Enable +- from JFLOP to the stepper driver?
see the above link and also this on channels.How do I configure Kmotion to tell it what is on each pin?
See the links above. Since your drives are Step/Direction like KStep the software configuration will be very similar.I've been reading the Kflop documentation for ~4 hours but still not sure about these basics, if there is a wiring guide and basic set-up please point me in that direction, most of the stuff I see uses Kstep so my set-up will be different.
