MatterSlice adds certain automatically generated code before and after your custom [[Settings/Printer/Custom G-Code/Start G-Code|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, then run the [[Settings/Printer/Custom G-Code/Start G-Code|custom start G-Code]], and finally wait for the extruder to finish heating before continuing.
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
