I've had an inverter on my prt alpha quite a while now, but I've never done more than use the wizards. I've tried using the inverter post in Part Wizard, but could never get it to work on my Y-axis indexer. I asked a friend of mine to write a program that would change the X axis coordinates to B axis degress. Well he did and so far it works pretty well. All I need to do is take my .sbp file from V Carve or Part Wizard or any other software with a Shopbot post processor, enter it into the program , follow directions and the software converts it for my indexer. I've cut a couple files and it seems to work great. I've converted some 3-D files from Mill Wizard and ran them in preview mode and all seems well. Give it a try and please post your results. It's set up for X or Y axis.http://www.spauldingbryant.com/sbconvert/
