step and dir pulse problem Mach3

Had a look at the diagram in the vfd manual.
S1, S2, FWD, REV all simply loop in parallel into the ground connection.
So if you want to use say a simple switch on the fwd, it simply goes- From FWD, into switch, out of switch, into ground. So, a straight ground sinking connection.
So for now get a simple 5v relay module on an AXBB-E output and simply use the NC/COM or NO/COM connections in the place of the simple switch I mentioned above on whichever controls you want.
Figure the AXBB-E board out later. Just going straight from an output alone won't work.

As for the 0-10v AVI. Your vfd looks to be 10v pot type operated analogue control. Have you set the jumper inside AXBB-E in correct 10v position?.
