Happy to report that I was able to flash all six PanelDues (four V2s & two V3s), and I'll accept user error. Let me explain what I did as I know others will likely fall into the same trap I did. I installed BOSSA like normal which includes the baked-in CDC driver. The port doesn't show up in Device Manager just yet. Plug in the PanelDue and the BOSSA Driver still doesn't show up yet. The instructions say to press the erase button. Well, I hadn't held the button long enough apparently. Windows will eventually detect and then you will see the BOSSA driver appear in the device manager. I may have figured this out sooner had I left the PanelDue plugged into the screen, but since I'm using a 7" screen, I was concerned about power - there was nothing wrong with having it plugged in, and it went black as it states in the instructions. 🤦 Now to plug back into the printers and see the fruits of my labor suffering.

if it is mid band resonance there is a good description here:

Hi guys, I had the same issue. The solution is to change the diameter of the part above the pcb. It should be around 17.5mm. My expirience is, that a bigger diameter makes it much worser.
