The first layer is essential for every Fused Filament Fabrication (FFF) 3D print, as it forms the foundation for the part to be printed. If the first layer does not stick to the build platform correctly, the print can move before it is completed, which will lead to a failed print.

The first layer adhesion also affects how easily the part will be removed from the build platform when the print is completed.

G-Code Files

AON3D has included two G-Codes files, as well as their factory file, for the user to practice, and get better informed on the process.

Each G-Code file will print a single layer rectangle shape, which will give the user the time needed to make minute adjustments to the Z-offset from the Graphical User Interface (GUI)/web browser.

The user must complete the Z-axis calibration before a first layer can be successfully printed.

File Description Usage
t0_z-calibration.gcode T0 Calibration For use with ABS
t1_z-calibration.gcode T1 Calibration For use with ABS
z-calibration.factory Base Factory File Modify to suit operator needs and choice of material

For instructions on how to inspect the AON3D build plates, refer to the Inspect and Clean Build Plates procedure.

Getting Started

  1. Load the ABS filament:
  2. Make sure that the build surface is clean:
  3. Preheat the build chamber and the build platform to the necessary print temperatures:
  4. Start the Automatic Bed Leveling (ABL) procedure once the build chamber components are at a stable temperature:
  5. Make initial adjustments to the toolhead Z-offset:
  6. Use the web browser to upload the t0_z-calibration.gcode into the AON3D machine.
  7. Use the GUI/web browser to start the t0_z-calibration.gcode.
  8. While the first layer is in progress, make small adjustments to the Z-offset as necessary.
  9. Examine the first layer print. If the results are satisfactory, select Stop.
  10. If first layer print is not satisfactory, do steps 7 to 9, as necessary.
  11. Do steps 1 to 10 for the adjacent toolhead, if necessary.

First Layer Offset Examples

Refer to the information that follows to get a reference of what to look for in the first layer print.

  1. A print with a Z-offset value that is too small (the nozzle is too close to the build surface) will be as follows.

    • Select Farther to move the print surface away from the nozzle, in small increments. Print Outcome with Head too Close to Print Surface
  2. A print with a Z-offset value that is too large (the nozzle is too far from the build surface) will be as follows.

    • Select Closer to move the print surface towards the nozzle, in small increments. Print Outcome with Head too Far from Print Surface
  3. The correct first layer will be as follows. Print Outcome with Head Properly Adjusted to Print Surface
