Having bought a mill without a DRO, many try to retrofit one to their equipment. This Mill in particular is quite small, which would make it hard to attach one. Also, i don't need a full DRO for my purposes currently. Thats what made me think about adding some simple measurement capability to 1 or 2 Axes of the Machine.
We need only the specs for T-Nuts of the correct size for the Mill. It uses M6 Hardware, so nothing special here. The Design can be adapted if you have a different T-Slot Size or your Indicator has a different shaft diameter. It's one of my most customizable projects.
