Login & Create Your Design

Start by logging into your 3DPlotter account. Once in the app, you can create designs using:

  • Text tool - Type with 50+ single-stroke Hershey fonts
  • Image upload - Convert photos to plottable vector paths
  • Drawing tools - Freehand drawing and shapes

Recommended Settings for Falu Pen Holder

Z-Draw (pen down)

14 mm

Z-Lift (pen up)

20 mm

These values work for most pens with the included Falu pen holder. You may need to adjust slightly based on your specific pen.

Configuration steps:

  1. 1Open the Settings panel in the app
  2. 2Select "Bambu Lab P1S" from the printer dropdown
  3. 3Set Z-Draw to 14 and Z-Lift to 20

Dry Run Test (Recommended)

Why Run a Dry Test First?

  • Verify the toolhead traces the correct paths before using ink
  • Ensure the design fits within your paper boundaries
  • Confirm the calibration sequence works correctly

Dry Run Steps:

  1. 1

    Start WITHOUT the pen holder attached

    Navigate to your G-code file on the P1S and start the print job. Do not attach the pen holder yet.

  2. 2

    Watch the calibration sequence

    The printer will run its calibration routine. This is normal.

  3. 3

    Printer moves to back center and waits 10 seconds

    After calibration, the toolhead moves to the back center of the bed and waits for 10 seconds. This is your window to attach the pen holder. For the dry run, just let it continue without attaching anything.

  4. 4

    Observe the toolhead movement

    Watch as the toolhead traces through all the paths. Verify it stays within your paper area and follows the expected design.

6

Attach Pen Holder & Plot

Now that you've verified the paths with a dry run, it's time to create your actual plot.

  1. 1

    Start the same G-code again

    Run the print job just like before.

  2. 2

    Wait for the toolhead to move to the back center

    Let the calibration complete. The toolhead will move to the back center of the bed.

  3. 3

    Quickly attach the pen holder (10 second window)

    You have 10 seconds to clip the pen holder onto the toolhead and insert your pen. The printer will beep and then automatically start drawing.

  4. 4

    Watch the magic happen

    After the 10-second wait, your P1S will automatically start drawing your design on the paper!

Pen Holder Attached to P1S

The Falu pen holder clips securely onto the front of the P1S toolhead.

Correct Pen Position in the Holder

Important: Position your pen so the tip aligns with the offset point shown below. This ensures the plotting coordinates match the settings configured in the app (Z-Draw: 14, Z-Lift: 20).

Troubleshooting Tips

Paths are offset from expected position

Check that you selected "Bambu Lab P1S" in the printer dropdown. The attachment offset is automatically calculated.

Pen doesn't touch the paper

Decrease the Z-Draw value (e.g., from 14 to 12). Each pen has slightly different dimensions.

Pen drags too hard on paper

Increase the Z-Draw value (e.g., from 14 to 16). The spring in the pen holder provides some flexibility.

Lines are broken or inconsistent

Ensure your pen has enough ink. Try a slower draw speed in the settings.
