Purge Calibration Test Kobra X

1 — Open the test file

Pick your printer/slicer file from your files, then:

1. Open Anycubic Slicer Next
2. Click Open Project
3. Open the 3MF file into a new project

You will then see the loaded project with several plates (depending on the number of colors).

2 — Set colors and flushing values

If you opened the correct file for the Kobra X1, there are only a few settings you need to change.

Steps:

1. Select the colors and filament you want to use
2. Go to:

Filament Settings → Flushing / Purge Settings

There you will see the purge values between colors.

Important setting:

You want this to be:

• Flushing volume: 50
• Multiplier: 1.00

If it looks different (which usually happens after changing colors), you need to change all flushing values back to 50.

3 — Check infill directions

Before slicing, verify this setting.

Go to:

Print Settings → Infill

Find:

• Sparse infill direction
• Solid infill direction

Both must be 0

If they are not, change them to 0 degrees.

Print Settings → Quality

• Print infill first enabled

This ensures consistent test results.

4 — Slice and print

Now you are ready to print the test.

Steps:

1. Choose which plate you want to print:

• 2 Colors
• 3 Colors
• 4 Colors

1. Click that plate to select it
2. Click:

SLICE

1. Load your filament if you have not already
2. Click:

PRINT

Or send the file to the printer and start the print.

5 — Expected result

Once printing finishes, you will have a strip with multiple transition blocks between colors.

Each block represents a different flushing amount.

6 — Reading the results

This is where you optimize filament usage.

Steps:

1. Carefully remove the samples
2. Place them on a white background (paper works fine)
3. Look at each sample and find the point where the previous color fully disappears.
