Mill Quill DRO: Installing the Magnetic Scale and Configuring it to Sum

Support Clough42 on Patreon: https://www.patreon.com/join/clough42

Today I'm finishing the install of the quill DRO on my PM935-TV milling machine. This adds a fourth axis to the 3-axis DRO already on the mill, and we'll set it up so the quill and knee DRO scale readings as summed together. This should allow us to move the knee and the quill at the same time and still retain our Z position.
