It's official: scanning is the new probing. In this video I take a look at the new eddy current bed scanning probe from BigTreeTech, aptly named Eddy, comparing it to the existing solutions as well as its closest rival: Beacon. I provide an overview of the device, the technology behind it, and a comprehensive installation and setup guide.
