speed_settings_initial_layer_speed
Printing the first layer slower than the rest of the print is a widely recommended practice. This helps ensure strong adhesion to the print bed, reduces the chances of warping or curling at the edges, and allows better compensation for minor leveling inconsistencies.
This setting determines the printing speed for the first layer, excluding solid infill regions. It applies to the outer/inner walls, sparse infill when bottom layers is set to 0.
Adjusting this speed helps ensure proper adhesion and print quality for the initial layer.
Defines the speed used specifically for solid infill regions on the first layer. These areas require more precise and consistent extrusion to create a flat and stable surface for subsequent layers. Printing this section too fast may result in high internal stresses (increased risk of warping), poor layer uniformity, or adhesion failures.
Sets the travel (non-printing movement) speed for the first layer. This doesn't affect the printing quality and can be set to a percentage of the travel speed.
Usually, this is set to 100% of the travel speed, but it can be reduced if you want to minimize vibrations or if your printer has issues with high-speed travel movements.
Specifies how many of the first layers should be printed at a reduced speed. Instead of jumping straight to full speed after the first layer, the speed gradually increases in a linear fashion over this number of layers. This gradual ramp-up helps maintain adhesion and gives the print more stability in its early stages, especially on prints with a small contact area or materials prone to warping.
