When I build the ox I would prefer to build the larger version. What will be the differences in terms of parts from the smaller. I realize the rails need to be longer and the belts but are there any other upgrades? I want to go through my parts to see what I have already. Thanks
You need more wheels to handle the weight of the larger gantry. I don't know how many you can mount on the custom OX plates but you could drill more holes.
