I have it together and running now. The 5i25 card + gecko drives have brought these steppers to life compared to the old probotix drives. I am now running them at 4 amps parallel. Before I had to limit my accel to under 20, and max speed at 100ipm.
Thanks for the input. So, for future readers, here is a list of my personal gotchas - Each stepgen takes control of 3 specific pins, which are listed here in prob_rfx2.pin. <http://www.mesanet.com/software/parallel/5i25.zip> The pins are not contiguous with their numbers, and are described in the 5i25 manual <http://www.mesanet.com/pdf/parallel/5i25man.pdf> page 9 and 10. Stepgen_maxaccel must be 20% higher than Max_accel. pncconf in beta 2.6.0 did not give me a correct setup, probably related to max accel and stepgen maxaccel out of sync. pncconf confused me, as the pins and numbers didn't seem to line up. All pins not used by the enabled modules are available for io.
