| − | 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 (<code>M104</code>, <code>M109</code>) in your custom start G-Code, it will remove these from the automatic G-Code. Likewise for bed heating commands (<code>M140</code>, <code>M190</code>).
| + | |
| − | | + | |
| − | 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

| − | MatterSlice allows you to place certain tokens in your custom GCode that will automatically be replaced with the appropriate values. Here is an example:
| + | |
| − | | + | |
| − | <code>M109 S[temperature]</code>
| + | |
| − | | + | |
| − | In this line, <code>[temperature]</code> will be replaced with the extruder temperature defined in your slice settings. These tokens can be enclosed in either square brackets <code>[]</code> or curly brackets <code>{}</code>, but for compatibility with other slicers we recommend square brackets.
