How to pause at a layer in Anycubic Slicer Next to change filament

In Anycubic Slicer Next, slice, drag the layer slider in Preview to the first layer of the new color, right-click the + handle, choose Add Pause, and slice again. The Kobra 3 stops there until you swap filament and resume.

Used with: Anycubic Kobra 3 and Kobra S1, printing without an ACE Pro. Checked against Anycubic Slicer Next 1.3 and later (September 2026).

Add the pause in Anycubic Slicer Next

  1. 1

    Slice and open the preview

    Click Slice plate. The Preview tab opens with a vertical layer slider on the right.

  2. 2

    Find the first layer of the new color

    Drag the slider up until the preview shows the first layer that prints only the new color, for example the first layer of raised letters above the base. The label shows the layer number and its height in mm.

  3. 3

    Add the pause

    Right-click the slider handle (the one with the + in it) and choose Add Pause. A marker appears at that layer. The printer stops just before printing it.

  4. 4

    Slice again, then print

    Adding a pause marks the slice out of date. Click Slice plate again, then send or export the file as usual.

The pause command

The Kobra profiles already have the pause command. The Kobra 3 also understands M600, which you can add with Add Custom G-code instead of Add Pause.

Swap the filament at the printer

Start the print with the first color loaded. When it reaches the pause:

  1. 5

    Wait for the pause

    The printer finishes the layer below and stops.

  2. 6

    Swap the filament

    Use the screen's filament controls to unload the old filament and load the new color. Purge until the color is clean.

  3. 7

    Resume

    Remove the purged strand without touching the print, then confirm on the screen to resume.

Remove a pause

Move the slider to the layer with the pause and click the × next to the handle, or right-click the handle and choose Delete Pause. Then slice again.

Tips and common problems

  • Pausing needs Anycubic Slicer Next 1.3.1 or later.
  • With an ACE Pro, you don't need a pause: assign each part its filament and the printer switches for you.
  • Add Pause is greyed out when the print sequence is By object. Set it to By layer in the process settings.
  • Avoid pausing in the first two or three layers: the print can cool and lift off the bed while it waits.

Common questions

Does the Kobra 3 support M600?
Yes. Anycubic says the Kobra 3 supports both M600 and M601. Add Pause uses M601; for M600, right-click the slider handle, choose Add Custom G-code and enter M600.
