Position Verification The "Ruppe" Test: DMM DYN4 Encoder signals piped into Acorn's Spindle Encoder

Terry Ruppe of Arrow Controls came up with the idea.
I decided to give it a go on my Emcoturn 120 lathe fitted with DMM DYN4 AC drives.
Seems an accurate way to test for lost/gained steps as the encoder is providing feedback to Acorn to display.
You do have to make up a cable that matches the DYN4 encoder pins(or any other drive that provides standard encoder signals) to the Acorn Spindle encoder pins.
