The method shown in the 📄"Passing Slicer Variables to PRINT_START" instructions is generally the preferable way to set it up, as it allows you the most control, but it is more complex.
If your slicer is putting heating g-codes AFTER PRINT_START and you want them to happen before (or the inverse, or you want to split it), this would be a simpler way to control the ordering. This method only allows you to send temperature g-codes before or after PRINT_START.
To force the g-code ordering, place any of the following g-codes from the following lists in your start gcode where you desire:
M140 S[first_layer_bed_temperature] ; set bed tempM190 S[first_layer_bed_temperature] ; wait for bedM104 S{first_layer_temperature[initial_extruder]+extruder_temperature_offset[initial_extruder]} ; set hotend tempM109 S{first_layer_temperature[initial_extruder]+extruder_temperature_offset[initial_extruder]} ; wait for hotend
M140 S{material_bed_temperature_layer_0} ; set bed tempM190 S{material_bed_temperature_layer_0} ; wait for bedM104 S{material_print_temperature_layer_0} ; set hotend tempM109 S{material_print_temperature_layer_0} ; wait for hotend
- These are just lists of available commands, they don't have to be in this order, nor do you have to use all of them. Place them as you like.
- Each bullet point is only ONE line. Do not split them into multiple lines.
- There are many other variables available in each slicer, and you can pass whatever variables you like to whatever g-codes you like. The available variables are not always documented.
Forces both bed and hotend to heat up fully before executing PRINT_START (SS):
