HI, We are curious has anyone experimented with using the BB AI with Machinekit yet? Either way, I was wondering if one was planning to do other operation such as in-browser 3d modeling (onshape, fusion360 or rhinoceros 7) as well as part scanning real-time whether it is yet a good time to try to transition over. Our project in general / non-machining parts level working well. Charles thanks so much for your help! But now we're about to size things up for longer axis of movement and more toque so along with moving to all larger NEMA 23 motors we are interested in considering BB AI. Especially if it is a drop-in replacement and still works with the CRAMPS Board and Configuration or if there is a new CRAMPS board that will be paired with it? Anyway, if anyone has thoughts or insights we are interested to hear them. Our goal continues to be to develop a sub $1000 (hopefully less) open-source 4 axis CNC for rotary machining bamboo pole stock. To help others to produce precice products and building system components, to democratize high craft for a highly sustainable material system.
