This is going through almost literally everything I could think of on trouble shooting and error proofing running the CNC test. There's a lot of variables to this on the work surface, work piece, and tooling head that I tried to look around the learning curve to prevent any failure in running this but not everything is as it seems through the software, use guide, and pre-sets established for this process. This video is slightly lengthy but there's a lot of going over measurements, parameters, and useful info you may not know. I'd recommend watching the majority of it if you're knew to desktop machines, CNC, or setting up light machinery.
