Hello John.

You have a better mill than I do.

Within >

I noticed RS522.
Since the predecessor networking protocol was RS485, and wondering if the RS522 
was a mis spelled RS422, I googled RS522.

    Did you put an RFID chip on all of your cutters and drills?

It's fairly robust.  Like a Grizzly G3616.

But it's got a poor excuse for an ACME feed not on the X axis with about 0.024" 
backlash.  Climb milling in the X direction with slow RPM and a large cutter 
causes the table to shake.  So once the spindle speed control system is in 
place the whole thing is coming apart for a ball screw retrofit.  And belt 
guards and covers etc.

So with the current backlash it may not be robust enough for round cutters.
