Thanks for the reply @nrp. One emi sticker did look a little close and I pulled it back. Unfortunately that didn’t fix it.
One last test I tried since I originally thought power. I have a usb-c power meter which I connected to a USB-C ssd and 1m cable.
Framework:
Idle: 4.99v
File Transfer: 4.92v(4.93v without module)/400mA. I also saw a rare dip to 4.85v/100mA
Macbook:
Idle : 5.16v
File Transfer: 5.09v/470mA, no dips.
I’m wondering if the disconnects are from falling too far below 5v under load? Other power sources I’ve tried also idle between 5.05-5.25v… wondering if its possible to raise the voltage on the Framework a bit and see if the disconnects go away.
