Thank you for the response. Inventables sent a replacement rod. Following your instructions and using the new rod I set it up and tested the run-out. Everything looks good. I can’t detect any movement.
That said…
My Z axis has never seemed right. Once I fixed the rod and tested the motor it was noisy, weak and changed direction intermittently. I fought with this for an hour and delved into the wiring. With nothing found I swapped the Z axis for the Y and retested. It worked perfect leading me to believe it was the shield. After a short time I found an open between the connector pin 4 and pin 18 of the Z axis driver. I fixed the connection and can finally say, I’m ready to start some test cuts.
You can see right side of Z driver toward the bottom were I added and reflowed the solder at pin 18
