Automatic G-Code Added Before/After Start G-Code
MatterSlice adds certain automatically generated code before and after your custom start G-Code. This normally where your temperature settings would be applied. MatterSlice will wait for the bed to warm up first. Then begin warming the extruder, run your custom start G-Code, then wait for the extruder to finish heating.
If MatterSlice detects that you have any extruder heating commands (M104
, M109
) in your custom start G-Code, it will remove these from the automatic G-Code. Likewise for bed heating commands (M140
, M190
).
Here are some examples of the automatic G-Code:
Before:
; automatic settings before start_gcode G21 ; set units to millimeters M107 ; fan off M190 S95 ; wait for bed temperature to be reached M104 T0 S210 ; start heating extruder 1 T0 ; set the active extruder to 0
After:
; automatic settings after start_gcode M109 T0 S210 ; wait for extruder 1 to reach temperature T0 ; set the active extruder to 0 G90 ; use absolute coordinates G92 E0 ; reset the expected extruder position M82 ; use absolute distance for extrusion
Variables
MatterSlice allows you to place certain tokens in your custom GCode that will automatically be replaced with the appropriate values. Here is an example:
M109 S[temperature]
In this line, [temperature]
will be replaced with the extruder temperature defined in your slice settings. These tokens can be enclosed in either square brackets []
or curly brackets {}
, but for compatibility with other slicers we recommend square brackets.
Here is the list of currently available tokens:
- temperature
- bed_temperature
- bed_remove_part_temperature
- extruder_wipe_temperature
- z_offset
- retract_length
- filament_diameter
- first_layer_speed
- infill_speed
- max_fan_speed
- min_fan_speed
- min_print_speed
- perimeter_speed
- retract_speed
- support_material_speed
- travel_speed
- bridge_fan_speed
- bridge_speed
- raft_print_speed
- external_perimeter_speed
- temperature
