I’ve increased my working angle to 11deg (from 8.5) after experiencing some Z axis problems while cutting my new sled. Finishing the sled tomorrow and then cutting 2 spares for the incoming ring kit. I’ll use this thread to document more changes as they come, but I’m very close to dialed in, I might be a .5-2 links off, but I’m on the rounder side of oblong on the sled and distances are all close enough for building more than tweaking😀
