EMC Setup Question - Axis Enable

Very excited! First time with EMC, installed ok, got it out of ESTOP, even
got one axis (Y) operating with JOG. Unfortunately, the other two (X and Z)
are not operational.

I suspect that it's because my stepper driver hardware (SP3 from
stepperworld.com) requires an axis enable signal (active LO) on pins 14, 16,
17 (C1, C2, C3) for each axis. Pins C1 and C3 are inverted by hardware and
are thus not working.

Is there an "axis enable" output in EMC, or must I try to jumper things on
the board. It does not, unfortunately, offer a jumper or connector, I would
have to mess with a soldering iron to make it work, I think.....
