Changing Filament to different color during print

  • I am trying to print an object with multiple colors with 1 extruder. I have set it to pause at 3 different layers and when I change the filament and press resume it doesn't start at the same position it left off at. I tried entering in the Pause G Code G91, G1 Z10 E-10 F12000, G90 on different lines. Then for resume G91, G1 Z-10, G90. I'm not an expert with the G Code. Anyone have any G Codes I can use in the pause and resume to make this work. Thank you

    @Randy406 My take is that the resume g-code needs to have a positive extrusion adjustment before printing, e.g. something like the following:
    G1 Z-10 E5.5 F12000
    If this does not work, then open a support ticket at to go into more detail.

  • Forget the g-code. When you want to change colors, wait til the printer is on the inside of the object. Have your new color ready. Release the feeder lock while printing, pull the old filament out, and insert the new color. Relock the feeder and you're in business. The printer won't miss but a small insignificant area. Try it!
