Step-by-Step Filament Color-Swap Tutorial

You do not need an expensive multi-material system (like Bambu AMS or Prusa MMU) to print dual-color nameplates and QR tags. By scheduling a layer pause in your G-code, you can change filament spools mid-print.

1. Determining the Swap Layer

Use the MakerKit3D Color-Swap Calculator to identify the transition point. For example, if your base plate is 2.4mm thick and printed at 0.20mm layer height:

Target Layer = (2.4 / 0.2) + 1 = Layer 13

2. Inserting Pause in PrusaSlicer / SuperSlicer

• Slice your STL model.
• Move the layer preview slider to the target layer.
• Right-click the small plus icon (+) on the slider and select "Add Color Change (M600)".
• Export the G-code to your SD card or send directly to OctoPrint.

3. Inserting Pause in Ultimaker Cura

• Go to Extensions > Post Processing > Modify G-Code.
• Click Add a script and choose Pause at Height.
• Change Pause at to Layer Number and insert the target layer calculated by our tool.
• Ensure Park Print Head coordinates keep the hot nozzle away from your print.
