XYZ all work OK, but I need A to work at least.
The limit settings seem very strange too, nothing is working as expected. I might have to toss this board and get a different one.
I have another board I will dig out, it is also a 5 axis I think, but this one has a parallel port connection, so I will have to use my old Dell computer for that board.
Mach3 won't change anything if you try and do it in the ports and pins sections etc.
As far as I read, these need to be changed in the plugin file for the board itself. That's what Mach loaded in when it changed.
Have a look in the Mach3 config folders for the usbMach (or whatever your board is) plugin.

You may be able to get round it for now by sharing the Pul Dir signal pins from the board to both the drivers to at least spin them.
One may go backwards and need wires reversing.

I have only read these 2 points from others and never tried either myself. Have a search around and see what you come up with.

DO NOT series daisy chain 2 motors to 1 driver unless the driver has double the output power of a single one.
This option may be suggested out there elsewhere.
