G-code
G-code is a set of instructions used by the printers firmware to interpret motor movements.
Slic3r transforms a 3D object into G-code. When printing the code is sent to the printer.
Slic3r supports variable substitution in G-Code. Any text in the form of [variable_name] will be substituted with the variable's value.
Example: If first_layer_temperature was set to 185c,
M109 S[first_layer_temperature] ; Wait for the extruder to reach temperature
Would be changed to:
M109 S185 ; Wait for the extruder to reach temperature
For more information about G-code go to: http://www.reprap.org/wiki/G-code
Start G-code is the code that will be executed before the actual print starts.
This code can do a variety of things, like home all axes, heat up the extruder and heated bed, ...
The default start G-code in slic3r is:
End G-code is the code that will be executed the printing is done.
This code can do a variety of things, like home all axes, turn off the extruder and heated bed, turn off the motors, ...
The default end G-code in slic3r is:
- M104 S0 ; turn off temperature
- G28 X0 ; home X axis
- M84 ; disable motors
