Your optional H2D USB flash drive may be impairing your prints

I don’t want to argue if this is what you experienced but I still wonder, the key is only to store logs and timelapses. You can also store the models you send for printing but for the actual printing, the gcode is read from the internal memory of the printer not from the stick.

Actually, credit goes to @krellboy 's comment on a different thread entirely about the side effects on printing from slow microsd cards:

What causes these blobs and how do I rectify

Yes, especially if you have a slow SD card.

that gave me the idea to look into whether slow USB sticks on the H2D might result in something similar and thereby explain the mysterious print defects I was having at the time.
