I have found that the SD card is not naitively supported on octoprint with the current configuration of marlin. Before i enable SD Card Support on marlin is there any reason this was left disabled? If i enable it is there any recommendations for setting the SPI speed?
The TFT24 touch screen interfaces through the printer's serial connection, essentially acting as a computer, it does not interact with marlin SD card support. Because of this octoprint would not be able to run with the SD card in the touch screen.
