Step 1 Before you start with Multi-Tool

This chapter shows a brief description of the wizard. Please note that the screenshots are illustrative and might differ from those in the firmware.

Make sure you are running Firmware 4.7.0 or newer

You can download firmware updates in Downloads. The guide for updating the firmware is in How to update firmware (MK4/XL)

Some parts of the wizard must be done multiple times, this depends on the number of tool-heads. For example:

⬢Dock Calibration

⬢Loadcell calibration

⬢Filament sensor calibration

Step 2 Preparing the printer

Make sure that the printer is placed in a stable place where no ambient vibrations are transmitted (for example, where other printers are printing).

⬢From the rear side of the printer, plug in the PSU cable.

⬢Turn the power switch ON (symbol "I").

Step 3 Factory reset

⬢After upgrading, the first thing we need to do is reset the printer to factory defaults.

⬢On the printer screen, go to Settings -> System -> Factory reset and select Reset Settings & Calibrations.

⬢Wait till the printer is ready.

⬢Restart the printer.

⬢Select the language you prefer.

⬢Good job. The printer is ready for Wizzard. Proceed to the next step.

Step 4 Prusa Nextruder sock (Optional)

⬢A silicone sock is supplied with each Nextruder package.

⬢If you want to install the sock, do it before the calibration.

How to install the sock - check the article.

Step 5 Wizard

⬢After the printer starts up, the screen prompts for the printer test and setup wizard.

The wizard will test all important components of the printer. The whole process takes a few minutes. Some parts of the wizard require direct user interaction. Follow the instruction on the screen.

NOTE: While testing the axes, make sure that there is nothing in the printer that is obstructing the movement of the axes.

WARNING: Do not touch the printer during the wizard unless prompted! Some parts of the printer may be HOT and moving at high speed.

Step 6 Wizard: Dock Position Calibration

⬢You will need:

⬢Universal wrench (1x)

⬢Mini wrench (1x)

⬢Dock calibration will guide you through how to properly calibrate the position of individual tool heads on the printer.

It is necessary to follow every step in the dock calibration properly! Do not rush, read every step twice, then proceed with the instruction.

Step 7 Wizard: Loosen pin

⬢Follow the wizard instructions on the screen.

⬢Using a Mini wrench, unscrew and remove both dock pins on Dock 1.

Step 8 Wizard: Loosen screws

⬢Follow the wizard instructions on the screen.

⬢Using a Uni wrench, loosen two screws. A few turns are enough.

Step 9 Wizard: Lock the tool

⬢Follow the wizard instructions on the screen.

⬢Manually move the Tool changing mechanism to the first tool.

⬢Manually lock the metal bars as described in the picture.

The tool has to be locked in the tool changer.

Step 10 Wizard: Tighten the upper screw

⬢Follow the wizard instructions on the screen.

⬢Using a Uni wrench, tighten the upper screw on a side of the dock.

After confirming by the continue button on the LCD, the XY axis will leave the dock with the tool. Clear the space.

Step 11 Wizard: Tighten the lower screw

⬢Follow the wizard instructions on the screen.

⬢Using a Uni wrench, tighten the lower screw on a side of the dock.

Step 12 Wizard: Install pins

⬢Follow the wizard instructions on the screen.

⬢Insert the two metal pins and tighten them with a Mini wrench.

⬢After clicking on the continue button on the LCD, the printer will put back the tool into the dock1 and do a few calibration moves.

⬢After the Dock1 calibration, proceed to the Dock2 calibration and repeat the steps.

Step 13 Wizard: Dock successfully calibrated

⬢Good job! The Dock1 is calibrated.

⬢According to the number of print heads, the dock calibration process is repeated.

⬢The next step of the wizard will prompt you to touch the nozzle to test and calibrate the Loadcell. During this procedure, the parts of the printer are not heated, you can touch the parts of the printer. Click on Continue.

⬢Do not touch the nozzle yet, wait until prompted with the message: Tap the nozzle NOW.

⬢Slightly tap the nozzle. No need to use extra force. In case the Loadcell does not detect enough touch, you will be prompted to repeat the step. Otherwise, you will see Loadcell test passed OK when it succeeds.

Step 15 Wizard: Recalibrate Filament Sensors

⬢After the upgrade, we need to recalibrate the filament sensors.

Your printer should have no filament at all.

⬢Please proceed through the filament sensor calibration. Follow the instructions on the display.

⬢Select NO, your printer has no filament at all.

⬢Wait for the printer to prompt you to insert the filament into the side filament sensor.

⬢Proceed to the next step.

Step 16 Wizard: Recalibrate Filament Sensors

⬢Now, insert the filament into the PTFE tube (the tool head you selected) in the side filament sensor and push it until it reaches the filament sensor in the extruder (you will feel a slight resistance).

⬢You can check the side filament sensor (left) and extruder filament sensor (right) status on the bottom bar on the screen.

It takes several seconds for the filament sensor to be calibrated.

⬢After the successful calibration, proceed on the screen by selecting Continue.

⬢Proceed to the next step.

Step 17 Wizard: Recalibrate Filament Sensors

⬢You will be prompted to remove the filament from the side filament sensor.

⬢Remove completely the filament from the side filament sensor.

⬢On the screen, select Finish and proceed with the calibration with all tool heads on your printer.

Step 18 Calibration pin: parts preparing

⬢For the next step, please prepare:

⬢Calibration pin (1x)

⬢Calibration-pin-key (1x)

Step 19 Calibration pin: parts assembly

⬢Insert the calibration pin into the plastic part.

⬢Push the pin into the plastic part, so it will make a small gap on top.

⬢Well done, the pin is prepared.

Step 20 Wizard: Tool Offset Calibration

⬢During offset calibration, you will need to screw the calibration pin into the center of the heatbed.

⬢Click on Continue to start the Tool Offsets Calibration.

⬢Calibration pin (1x)

Step 21 Wizard: Sheet install

⬢Follow the wizard instructions on the screen.

⬢Put the steel sheet on a heatbed.

Now, the printer starts short calibration.

Step 22 Wizard: Calibration pin installation

⬢Follow the wizard instructions on the screen.

⬢Take off the steel sheet from the heatbed.

⬢Install the calibration pin into the middle of the heatbed. Turn the pin clockwise.

Now, the printer will calibrate all five tool heads.

Step 23 Wizard: Offset calibration done

⬢Follow the wizard instructions on the screen.

⬢Untighten the calibration pin from the heatbed and take it off. Rotate counterclockwise.

⬢Place the steel sheet on a heatbed.

The printer will finish the calibration.

⬢Good job! The Offset calibration is done.

Step 24 Calibration pin

⬢Insert the calibration pin into the side filament sensor.

Step 25 It's done

⬢That's all, the printer is ready to print. But still, follow the instructions in this manual to the end.

Step 26 Reward yourself!

⬢It looks like you have successfully assembled and connected everything. No doubt ;). Congratulations! You deserve a big reward for that. Eat all the remaining gummy bears... and don't forget to share with those who supported you during the assembly.

Did you know that Haribo gummy bears are one of the most important parts of the Original Prusa printers assembly instructions.
