Hmm, you need to try and see :) Experiment a bit - I have never used a fsbus stepper module myself. This is just how I would think it might work. :-)Try with something simple, like plastic cans and lids or such, to see a proof of concept first, then once you figure out how it works (and tell us too! :)) - then you can better design how to set it up on the final gauge.//Tuomas

I plan to cut out the parts on the cnc this weekend and assemble the project. As a prototype, it doesn't matter if I have to recut parts and make mods to them. I will keep you updated.David
