Step 1 Z axis and first layer calibration (optional)

IMPORTANT: This step is necessary only in case you have adjusted the position of the SuperPINDA sensor in the previous chapter. Otherwise, you can skip to the next step and use the Live Adjust Z function as usual to fine-tune the first layer.

⬢Go to LCD Menu - Calibration - Calibrate Z.

⬢Then run the First Layer Calibration.

Step 2 Loading a sample G-code to the printer

As a first print please print the Sheep, which is pre-sliced and tested. In case of any issues, it will make troubleshooting much easier.

⬢Visit our PrusaPrinters.org profile to download a pre-sliced G-code for your printer.

⬢Or go to the folder Prusa3D/Sample objects/MMU2(s) via the link on your desktop. The link installs together with a full installation of the PrusaSlicer.

⬢load the PLA_Sheep_200um G-code to SD card and insert the card into your printer.

Step 3 Start the print

⬢Start the print and wait until it is finished. In the meantime you can take a look in the printed Handbook (included in the package).

⬢If you are having any issues while printing, see our troubleshooting articles such as the MMU needs user attention.

Step 4 Handbook and Troubleshooting

⬢

All the information regarding calibration, how to organise the printer, buffer, spools, or troubleshooting tips are all in the printed or online Handbook.

To download the Handbook or if you encounter any issues, please visit our knowledge base at: http://help.prusa3d.com/en/tag/mmu2/

Step 5 Printable 3D models

⬢You can start by printing some of our test objects that can be found at www.printables.com

Step 6 G-code preparation / Custom model preparation

⬢Already printed all the bundled multi-material models from us and seen all the others from http://PrusaPrinters.org? Time to print your own designs!

⬢Basic steps are described in our G-code preparation for multi material print section.

⬢Definitely try out the MMU Painting function in PrusaSlicer for the models with a single body.

Step 7 Making your own Multi-material models

⬢If you have designed your own model, you may find Exporting a model from Fusion 360 guide useful.

If you have an STL file and want to print a large and complex part of it in a different color, then check Splitting STL with single compact part or the Splitting STL using MeshMixer guide.
