I bought this at an auction and would really like to find the CAD drawings for it. I am pretty sure this was build from plans on this site as there are openbuilds stickers all over it. Just haven't found it yet. I belive it's from 2016. Here is what the plates look like.
You got more of an overview pic? Best I can guess from that is one of the earlier OXes that generally had custom gantry plates.
Looks like a custom Cbeam build. If anything exists on it it’ll be in the CNC builds section. Don’t recall ever having seen it though.
