Step 1 Connecting the extruder cable bundle

⬢Find the slot for the NYLON filament on the Einsy-base. You will need it in the next step.

⬢Before we proceed further, we need to twist the textile sleeve. This will prevent the cables inside to slip out during the printing.

⬢Using your fingers, gently twist the sleeve (not the cables) and create several wraps.

⬢Twisting the sleeve will effectively shorten its length. In the following steps, you might need to untwist the sleeve slightly to elongate it.

Step 2 Connecting the extruder cable bundle

⬢Slide the NYLON filament in the hole.

If the nylon is hidden inside the textile sleeve, use the technique in the previous step to reach it.

⬢Make sure the filament isn't pushing into the X-axis motor cable. This would indicate it is too long and you need to slightly unwrap the sleeve and push the filament back.

⬢Slide the sleeve in the holder at least 3/4 of the holder's height.

Again, ensure the filament isn't pushing the cables and if needed slightly unwrap the sleeve and push the filament up.

⬢Use the Extruder-cable-clip and two M3x10 screws to fix the cable bundle in place.

Older MK3 units may have a zip tie cable harness mounting. Use a zip tie to secure the textile sleeve. Do not overtighten the zip tie, you can damage the cables!

Step 3 Connecting the cables (MK3 to MK3S+ upgrade)

If you are upgrading from MK3S to MK3S+,please skip this step.

⬢Connect all unplugged cables according to the wiring diagram.

Some units may be without a plug-aligner (orange frame in the filament sensor slot). It has no effect on the function of the printer.

Make sure once more the Filament sensor cable is connected to all pins! Misalignment might lead to permanently damaging the sensor.

⬢Check your electronics connection according to the wiring diagram.

Step 4 Connecting SuperPINDA cable (MK3S to MK3S+ upgrade)

If you are upgrading from MK3 to MK3S+, please skip this step.

⬢Connect the SuperPINDA sensor to the Einsy board.

⬢Check your electronics connections according to the wiring diagram.

⬢To make sure, check the correct connection of the filament sensor cable. The connector must be plugged into the bottom row of the slot. Misalignment might lead to permanently damaging the sensor.
