I just opened my new in the box Shapeoko 3, but I think it is from 2015, or perhaps early 2016. The controller is version 2.2. Aside from that, I don’t know if there is any easy way to figure out the date on this thing. I was originally eager to try to get all of the 2016 upgrades, but perhaps that isn’t necessary. Carbide 3d offered me a couple of options. 1, I could just upgrade items piecemeal and they would do their best to invoice me for the parts I want. 2, bite the bullet and upgrade to XL. Most of the 2016 upgrade parts would be covered in that purchase. 3, Just build and use the system as is. Perhaps the wider belts are no big deal, but the stiffer z plate might be worth it under any circumstances?
2 questions. What is the current controller board version number? What upgrades are most worth paying extra for at this point?
