Step 1 Introduction

⬢This guide will take you through the lubricating of the Tool-changer on the Original Prusa XL (Multi-tool).

The following instructions are intended for XL Multi-Tool only.

Before you start with the printer surgery, download and print the required lubricant applicator tc_greaser from Printables.com.

Step 2 Tools necessary for this chapter

⬢For this chapter, please prepare:

⬢Prusa lubricant (1x)

⬢tc_greaser (1x)

⬢Cardboard box at least 20 x 20 cm to protect the heatbed Hint: use the original Nextruder box.

⬢Cloth or piece of fabric or paper towels to clean the parts.

Step 3 Parking the Nextruder

⬢If the tool-changer holds the Nextruder:

⬢On the xLCD, go to Control -> Pick/Park tool -> Park current tool.

Wait for the printer to finish the parking.

⬢If are all your Nextruders parked, proceed to the next step.

Step 4 Preparing the printer

⬢From the rear side of the printer, turn the power switch OFF (symbol "O").

⬢Move the tool-changer manually to the front side of the printer.

⬢To protect the heatbed, place the nextruder box on it.

Step 5 Assembling the applicator

⬢Open the lubricant by twisting the lid and turning it 180°. Press the lid through the metal seal to open the lubricant.

⬢Attach the tc_greaser to the Prusa lubricant. Turn clockwise to secure.

⬢Try to squeeze it a little, the lubricant should come out through the holes in the inside of the tc_greaser.

Step 6 Detaching the Nextruder

⬢Gently remove the selected Nextruder from the dock.

⬢Place the Nextruder on a box on the heatbed.

Step 7 Cleaning the coupler screws

⬢On the tool-changer, locate 3 coupler screws.

⬢Using a cloth or paper towel, clean all coupler screws.

Step 8 Lubricating the coupler screws

⬢Take the lubricant with the applicator.

⬢Lubricate the upper screw by applying the lubricant and gently squeezing the lubricant. After squeezing, rotate the applicator to ensure even distribution of the lubricant.

⬢Repeat the same process for the lower right screw.

⬢Repeat the same process for the lower left screw.

Step 9 Checking the grease

⬢Visually check lubricant levels on each screw, ensuring sufficient coverage. Refer to the provided pictures for comparison.

Pay attention to the screws specifically, avoiding excess application on other parts!

⬢Use a paper towel to thoroughly clean grease from the area around the screws.

Step 10 Parking the Nextruder

⬢Take the Nextruder and line up it with the appropriate dock.

⬢Attach the Nextruder to the dock by sliding two pins into the holes in the dock.

Ensure, the Nextruder is parked correctly.

⬢Proceed with these steps sequentially for the remaining Nextruders.

Step 11 That's it

⬢Remove the cardboard box from the heatbed.

⬢From the rear side of the printer, turn the power switch ON (symbol "I").

⬢Good job! You successfully lubricate all tool-changers on your printer.
