Hey GregZo,
for your VFD? For me, a VFD is this. Did you really mean “VFD”?
Thank you for blogging about your CNC projects! It’s always a pleasure to see the details of such a project and with good photos.
The only thing that is a bit surprising is that you did not make the drag chain wider, and be it as reserve for possible future additions. In my understanding, for a machine with water-cooled, but non-ATC spindle, when it comes to Drag Chain Width Computation I see 50 mm for the X axis and 76 mm for the Y axis as minimum.
