1 Start G-code

This start procedure is inserted at the beginning, after any printer start gcode. This is used to override settings for a specific filament. If Slic3r detects M104, M109, M140 or M190 in your custom codes, such commands will not be prepended automatically so you're free to customize the order of heating commands and other custom actions. Note that you can use placeholder variables for all Slic3r settings, so you can put a "M109 S[first_layer_temperature]" command wherever you want. If you have multiple extruders, the gcode is processed in extruder order.

3 Use volumetric E

This experimental setting uses outputs the E values in cubic millimeters instead of linear millimeters. If your firmware doesn't already know filament diameter(s), you can put commands like 'M200 D[filament_diameter_0] T0' in your start G-code in order to turn volumetric mode on and use the filament diameter associated to the filament selected in Slic3r.

6 Z full steps/mm

Set this to the number of *full* steps (not microsteps) needed for moving the Z axis by 1mm; you can calculate this by dividing the number of microsteps configured in your firmware by the microstepping amount (8, 16, 32). Slic3r will round your configured layer height to the nearest multiple of that value in order to ensure the best accuracy. This is most useful for machines with imperial leadscrews or belt-driven Z or for unusual layer heights with metric leadscrews. If you still experience wobbling, try using 4 * full_step to achieve the same motor phase pattern for every layer (important for belt driven z-axis). Set to zero to disable this experimental feature.

Note that you can use placeholder variables for all Slic3r settings, so you can put a "M109 S[first_layer_temperature]" command wherever you want.

6 Between objects G-code (for sequential printing)

This code is inserted between objects when using sequential printing. By default extruder and bed temperature are reset using non-wait command; however if M104, M109, M140 or M190 are detected in this custom code, Slic3r will not add temperature commands.
