| + | === Wait for Temperature === | ||
| + | Your 3D printer must wait to get to temperature before trying to prime the extruder. Without doing so, it will do nothing but grind the gears on the filament (or crush flexible filament) unless it is still hot enough from a print immediately beforehand. However, the three lines below only have software-specific notation. | ||
| + | |||
| + | **If you are using Cura, then you do not need to add these lines to your start gcode, they are automatically added.** | ||
| + | |||
| + | If you are using Slic3r, then you may want to check that you have the following lines in your start gcode. | ||
| + | |||
| + | For Slic3r: | ||
| + | * M190 S[first_layer_bed_temperature] ; Set bed temp. | ||
| + | * M140 S[first_layer_bed_temperature] | ||
| + | * M109 S[first_layer_temperature_0] | ||
| + | |||
| + | For Cura you can add additional wait commands to the start gcode if you want, but note that the format is slightly different [[https:// | ||
| + | * M190 S{print_bed_temperature} ; Set bed temp. | ||
| + | * M140 S{print_bed_temperature} ; Wait for bed temp. | ||
| + | * M109 S{print_temperature} ; Wait for all used extruders to reach temperature. | ||
