Addressing First Layer Adhesion Issues with Artillery 3D Printers
Some new users of Artillery 3D printers may encounter issues with printed parts not sticking firmly to the PEI plate, leading to failed prints when the part detaches during printing.
This problem often stems from the default print profile provided on the Artillery official website, which has an issue with the first-layer settings.
In the PLA Filament settings within Orca Slicer, under the Advanced tab, you’ll notice the G-code M109 S190 . This command instructs the printer to start printing once the nozzle reaches 190°C. However, even if the nozzle’s first-layer temperature is set to 210°C, this G-code overrides it and initiates printing at 190°C.
For many PLA filaments, 190°C is too low for the first layer. Combined with the printer’s default first-layer speed of 50mm/s and the part cooling fan only starting from the second layer onward, this can result in poor adhesion to the PEI plate.
Many users may not notice this detail, leading to a frustrating experience with the 3D printer.
How to Resolve the Issue
To improve first-layer adhesion and avoid print failures, it’s important to adjust filament settings and amend the start G-code.
1. Amend the Start G-code
Update the G-code to ensure the nozzle reaches the correct temperature before printing begins. Replace M109 S190 with M109 S{nozzle_temperature_initial_layer[initial_extruder]}. This change ensures the nozzle will heat to the temperature you’ve set for the first layer before starting the print.
2. Optimize First-Layer Settings
-
- Set the nozzle temperature for the first layer to 210°C.
- Adjust the first-layer printing speed to 25mm/s for better adhesion.
- Delay the cooling fan start to the third or fifth layer.
3. Alternative for Higher Speeds
If you prefer to keep the default first-layer speed of 50mm/s, increase the nozzle temperature for the first layer to 220°C. This approach has been tested and proven effective.
By making these adjustments, you can ensure a smoother printing experience and significantly reduce the likelihood of first-layer failures.
