SD card printing - prevent buffer underruns

Hi,

As the software is still not useable I tried to print via USB which worked well on low speed (and you can use your own filament :wink: )

Has anybody tried to print via SD card?
I can load the sd card but it takes AGES to load a gCode from it to print without a cable (and to gain much better speed as the USB speed is very limited…)

I also have tried run my Zeepro via OctoPrint on a RaspberryPi which worked well but I do have the same limitation on the USB port. By the way even the webcam is useable as it is a simple USB camera :wink:
