I did build a CoreXY system and tested it out, right around the time of the MRRF. I really had high hopes for the CoreXY as well, it seemed like a really elegant design. Unfortunately once the system was built the tests didn't really go all that great.
-The system was really slow, acceleration wasn't there. Forget about 300mm/s, it just wasn't going to happen. At least with it's current state in firmware.
-While the part count does go down, the complexity went up.
-It seemed the CoreXY Marlin had some bugs at the time, hopefully they are worked out. But the printer would seem to lose its place/drift, and it wasn't motor driver issues. Though it could have been a side effect of us trying to operate at high speed.
-There's so much belt that it's going to be hard to keep from having to tighten your belts every couple months. The added length gives them much more room to stretch out.
On the upside it was really smooth and is well suited for FFF printing, and it also reclaimed some of the X/Y axis travel.
If anyone has questions about that project please just let us know.
