Page 6: Quick-Start Instructions
2 Quick-start instructions We get it. You just a ssembled the MMU2, connected it to your printer and now you are eager to start printing :) But give us just a second! There’s a couple of important steps you need to take before you can print your first multi-material G-Code. -
Page 7: Placement And Setup
3 Placement and setup Arrange the the spool holders next to each other at least 40 cm behind the back of the printer. Pict. 2 - Placement of the spool holder During filament changes, all of the filament is unloaded from the orange PTFE tube. The printed parts attached to the spool holders are designed to create loops of filament instead of letting it fall down from the spool and possibly getting tangled up. -
Page 8: Flashing The Firmware
4 Flashing the firmware Before you start using the MMU2, the p rinter’s firmware needs to be updated, otherwise the printer won’t communicate with the new unit. The MMU2 motherboard can be also updated with a new firmware, which comes as a separate file. Please keep in mind that there are slightly different flashing procedures for each board and that firmware files for the printer and the MMU2 can be released independently. -
Page 9: Loading/Unloading/Selecting Filament
To flash firmware on MacOS or Linux, please download the latest version of Slic3r PE for your system, then download the firmware files and follow the procedure described above. Downloading and installing USB drivers is not necessary. The firmware for our lineup of printers is updated regularly. To ensure the best possible experience when working with the printer and the MMU2, it is necessary to always use the latest firmware. -

Page 11: Explained
If you want to verify proper load of all five filaments before print, select L CD Menu - Load filament - Load all. T he MMU unit should quickly try loading and unloading all 5 filaments one after another without any user interaction. After the last position, the LCD Menu should quickly try loading and unloading all 5 filaments one after another without any user interaction. -
Page 12: Calibrate The Z-Axis
6.1 Calibrate the Z-axis In your printer’s LCD menu, go to M enu - Calibration - Calibrate Z and let the printer run the calibration procedure. The procedure consists of raising and lowering the Z-Axis and measuring 9 points on the print bed. Pict. - Page 13 Pict. 9 - How to tune the nozzle height in real time during the test print. Note: -0.640 mm is only for illustration. Y our setting will be different! Observe the line which is being extruded on the print surface. A new menu will automatically show up, with an option to tune the nozzle height in real time by turning the knob.
