SD transfer

Important The SD transfer uses the GCODE protocol based on M28/M29 commands. This protocol is often broken by external queries or auto reporting. Additionally, the SD transfer is very slow: ~0.4KB/s, which makes it almost unusable.

So this protocol is no longer supported in ESP3D, and the feature is provided as it is.

For file transfert, the only existing reliable solution for ESP3D 2.1.X is a WiFi SD card such as Toshiba FlashAir or FYSETC SD WIFI Pro.

ESP3D 3.X has some existing solutions and ongoing plans for better SD support depending on the hardware used.
