But notice something interesting, the garbage output is not similar between the Wemos pro mini and the Wemos D1 mini V3 The pro mini output looks like this : ph⸮ph⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮M115...

I reflashed Marlin 2.0 with 115200 yesterday and that didn't fix the issue. I also changed PrinterSerial.begin(serialBauds[serialBaudIndex]); to PrinterSerial.begin(115200); still no go... :(

I am pretty sure there is some kind of voodoo involved :)

This might have been the reason why grafana iframes are not scaled. I am trying to properly scale them in Habpanel with no luck. Any suggestions?
