It just logging gcode
you do a "M28 filename.gco"
then all aditional gcode is then saved into that file instead of being actioned
"M29 filename.gco" closes the file
And yes its slow on a ramps, its over serial, so it uploads at what ever serial rate you have set in your firmware, normally 250000
plugging the SD card into your computers usb port is much faster, about 320000000 baud...
