Mach 3 default settings,

[JAZZCNC]

Well I suggest you update the Firmware on the Cslabs unit to latest Firmware just to be sure. Then Re-install Mach3 and Cslabs Plug-ins.
Re-enter all your settings.

If you still have axis that don't move then I suggest you swap the non working axis drives with the ones that do work just to eliminate you don't have faulty drive/s.

If not faulty drives and your 100% sure the connections correct and sound then send the IP-S unit back to Cslabs because you either have faulty unit or it's broken by something you did wrong?. In which case you won't know if the troubles you are having are because of this or down to you not setting correctly.

It's very unusual to have these kinds of trouble with Cslabs stuff if the pins are connected correctly and understand the difference in way it works compared to mach3 normal way of working.
