Step 1 Wrapping the cable bundle

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

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

⬢Twisting the sleeve will effectively shorten its length. In the next steps you might need to twist the sleeve slightly back to lengthen it.

Step 2 Checking the hotend cables

⬢Let's make sure the cables from the hotend aren't in contact with the heatbed.

⬢By rotating the threaded rods at the same time, lower manually the X-axis down until the nozzle is almost touching the heatbed.

⬢In case the P.I.N.D.A. sensor touches the bed before the nozzle, move it up slightly.

Ensure there is a gap between the screw in the heatbed and the surface of the hotend cables. The gap should be 2-3 millimetres, the steel sheet will add another 1 mm.

In case the cables are rubbing against the screw, adjust them (push them up in the extruder)

In case you are unable to adjust the cables, unscrew the M3x10 screw and use a spare M3n nut to shorten the length of the thread. Then place the screw back.

Step 3 Connecting the extruder cable bundle

⬢Slide the NYLON filament in the hole.

⬢Make sure the filament isn't pushing into the motor cables, which 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 motor cables and if needed slightly unwrap the sleeve and push the filament up.

⬢Depending on the version of your Einsy-base, use either the zip tie or the Extruder-cable-clip and two M3x10 screws to fix the cable bundle in place.

Step 4 Connecting the extruder cable bundle

IMPORTANT: Connecting the filament sensor cable properly is crucial. If you don't follow the instructions properly, you will burn the sensor!!!

DON'T CONNECT THE CABLE NOW, wait for the next step!!!

⬢In case you have printed the plug-aligner, gently push it in. The notch should be oriented up, like in the picture.

⬢There are two rows of pins in the connector:

⬢Lower row (for MK3S) use these pins to connect the IR-sensor.

⬢Upper row (for MMU2S) these pins won't be used in this manual.
