Added new variable "extr" in Json response to report extruder positions Added new fileinfo request type, returns file size, object height, and total filament needed (if available) Fixed bug in returning last command response in Json response Disable interrupts when adding/removing network request structs from linked lists, in case lwip does callbacks from ISR contexts

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.
|
|
|
|
Most of the functions in here are designed not to wait, and they return a boolean. When you want them to do
|
|
something, you call them. If they return false, the machine can't do what you want yet. So you go away
|
|
and do something else. Then you try again. If they return true, the thing you wanted done has been done.
