On the begging of the 9th layer, see step one.

This particular print switches colors on layer 9 out of 11 layers. The red arrow above indicates what layer the print is on.

Step one, click the pause button.

  • See red circled tabs.

Step two, Raise your Z axis.

  • I raise the extruder 10 increments for ease of performing step three.

Step three, clip excess filament  that's stuck to print.

  • When I first did this I felt rushed, there's no reason to hurry to continue the print.

Step four, swap out the last color with the new one.

  • Squeeze the head fixture(not holding the fan).

Step five, Continue printing

  • When continued is clicked, the extruder will lower to the same point raised from and begin printing again.
