Hi,

i have 2 steppers on the same axis with AM882 drivers,
I could use the slaved axis in Mach3, but

1 - is there a solution to slaving an axis in hardware with a purerelogic PLC4X-G2 Breakout board ?
i know that i can hardware slave a stepper with a pmdx-126 http://www.pmdx.com/PMDX-Forums/index.php?topic=101.0

2- is it better than using the slaved axis in Mach3 ?

( why using PLC4X-G2 : is cheaper and the VFD is included, and the motion controler PLCM-E3 can be added in the future for less than a SmoothStepper).

3 - I've read on the manual of the PLC4x-G2 http://www.zappautomation.co.uk/prod...download?id=99 that i can do something with the XP-23 expansion "2 step motor drivers can be additionally connected through expansion socket XP23 if it is necessary" But how ? do i need a second PLC4X-G2 or an expansion board ? because i don't see any step and dir on XP23 connector ?

Thanks for your help.
