Fixed bug with reading file info Don't return status as Printing if just running a macro Restored Json buffer back to 2000 bytes so as to return more files on SD card Limit the amount of moves we buffer so as to react faster to speed and extrusion rate changes Return print time left estimates in M105 S2 status response if printing a file Show stepper motor currents as integers and do some rounding to get more accurate values

RepRapFirmware - G Codes
|
|
|
|
This class interprets G Codes from one or more sources, and calls the functions in Move, Heat etc
|
|
that drive the machine to do what the G Codes command.
