Safety glasses will need to be worn when shortening the nylon filament. It is not necessary to put the glasses on immediately. You will be prompted in time.
⬢Locate the hole for the NYLON filament in the cable opening. Using the smallest Allen key, ensure there are no obstacles inside.
⬢Using the pliers insert the NYLON filament with the pointed end into the slot. Twist the filament while pushing it in. Hold the extruder with your other hand.
⬢Once the nylon filament is successfully inserted, position that it inclines upwards as seen in the picture.
⬢Open one end of the textile sleeve and slide it on the cable bundle leading from the extruder. Don't forget to include the black nylon filament inserted earlier!
⬢The length of the first wrap should be slightly longer than the cable-holder part, about 5 cm is enough.
⬢Take 3 zip ties and insert them into the lower row of holes on the cable-holder.
⬢Slightly twist the textile sleeve around the cable bundle.
⬢Secure the cable bundle by tightening the three zip ties.
IMPORTANT: Cut the remaining part of each zip tie using pliers as closest to its head as possible. Note the correct position of each zip ties's head (slightly off-centre to the left).
⬢Include the hotend cables to the cable bundle and wrap it into the textile sleeve.
⬢Now we will plug each extruder cable into the MK3.5 adapter cable. Follow the markings on the adapter cable and the markings and colors of the cables guiding from the extruder.
In the following pictures showing the connection of the cables, the MK3.5 adapter cable is always the one at the bottom (always with the yellow cable marking).
⬢Plug the Extruder motor cable into the adapter cable labeled "E".
⬢Plug the Hotend thermistor cable (red & black wire) into the adapter cable labeled "H".
⬢Plug the SuperPINDA/P.I.N.D.A. sensor cable into the adapter cable labeled "P".
P.I.N.D.A. sensor cable has four wires instead of three (SuperPINDA) in the connector and can have a black or grey colored protective sheath.
⬢Plug the Hotend Fan cable into the adapter cable labeled "HF".
The design of the hotend fan cable may vary depending on which variant you have. Either a cable bundle wrapped with a textile sleeve or bare cables without a wrap.
⬢Plug the Filament sensor cable into the adapter cable labeled "F". The red wire on the Filament sensor cable and the xBuddy adapter cable must be on the same side!
WARNING: Correct wiring is critical! Failure to do so may irreversibly damage the electronics.
⬢Plug the Print Fan cable into the adapter cable labeled "PF".
⬢Peel of the adhesive tape paper layer from the NFCcoil.
⬢Stick the NFCcoil on the inner side of the El-box-cover approximately like in the picture. See the correct orientation of both parts!
⬢Leave at least 2mm space between the NFCcoil end the edge of the El-box-cover.
⬢Locate the small round connector on the NFCcoil.
⬢Connect the NFC coil cable to the board by fitting the connectors together and pressing lightly until you feel a click, ensuring a correct connection.
Ensure the NFC antenna cable connector is securely plugged in and does not come loose from the board.
BE EXTRA CAREFUL when connecting the NFC antenna cable connector. Excessive pressure or misalignment can cause irreversible damage.
⬢Locate the small round connector labeled NFC on the bottom left side of the xBuddy board.
⬢Connect the NFC coil cable to the board by fitting the connectors together and pressing lightly until you feel a click, ensuring a correct connection.
Ensure the NFC antenna cable connector is securely plugged in and does not come loose from the board.
BE EXTRA CAREFUL when connecting the NFC antenna cable connector. Excessive pressure or misalignment can cause irreversible damage.
⬢Attach the cover to the xBuddy Box. There are two threaded holes in the xBuddy box. Make sure there is no cable in the way for the screws and the cover.
⬢Secure the el-box-cover by tightening both M3x10 screws to the xBuddy box.
Be careful not to pinch the NFC cable when closing the cover.
This step is optional, but recommended. The safety label for the MK3.5 has been updated with new symbols that align more closely with international markings.
⬢Peel off the old safety label from the right side of the frame.
⬢Using the IPA cleaning pad (included in the kit package) clean the area of adhesive residue.
⬢You made it! Congratulations. Your MK3.5 is almost ready for printing.
⬢Almost? Just one small chapter that will guide you through the calibration and self-test.
⬢Go to the last chapter 8. Preflight check
