Here is a video of my machine making the noise when jogging the X axis: https://www.dropbox.com/s/qy3j1zjpz6hxqp4/2019-05-28%2009.21.15.mp4?dl=0
I have attempted to re-seat my stepper connectors and verified all the wires on the wiring harness are connected to the best of my knowledge.
This symptom started happening after installing an Aerostruder tool head. But continued to happen after going back to the stock tool head.
The version of the firmware in the video is super old because I was trying different versions thinking that was the problem but the issue still happens in version 126.96.36.199.
Thanks for any help/advice.
