made a little progress, discovered you have to use the POBlocks program to access the pulse engine, you can't do it from the plugin configuration.
But now another step backwards, Using the POBlocks program, after unlocking and inverting the Dir pin, then saved configuration, then send settings to device, exit program. No change in the operation of the x jog it is still backwards.
I then went back into the POBlocks program and it was not changed, it had the invert Direction pin unchecked.
Help??
