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".
⬢Check your electronics connection with the first picture.
Before covering the electronics, check and compare your wiring.
⬢Compare your cable management with the second picture. Guide the cables along the inside of the box and maintain clearance above the electronics board for better cooling.
⬢Tighten the cable bundle with two zip ties that are already prepared in the xBuddy box.
Make sure that all connectors are fully inserted and PSU cables properly tightened. Otherwise, there is a risk of damage to the printer!
⬢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.
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.
Applying the xLCD sticker is entirely optional, yet it serves as the finishing touch that adds a final detail to the whole assembly :).
This and the following steps are optional. Also, please BE PATIENT, smaller letters require more effort in order to be transfered and glued properly.
⬢Using the cleaning pad, clean the side without the circle hole on the xLCD-cover.
⬢Peel off a piece of the protective layer and carefully attach the label on the xLCD-cover. Maintain the label aligned with the edges of the display cover. Start on the bottom side.
Notice the white PRUSA lettering through the sticker. Compare the orientation with the second picture.
⬢After attaching the sticker, run your finger along the entire length of the sticker in all directions to ensure perfect adhesion.
This process requires patience and care. Perfect adhesion depends on proper degreasing of the part and the ambient temperature.
⬢Start slowly peeling off the application layer. Lightly press the layer onto the lettering as you peel it off. Observe whether all the letters are glued on.
⬢After peeling off the application layer, check that the final look matches the picture.
⬢To avoid the concern of having leftover nuts and screws, refer to the following list of fasteners that should remain unused from the initial package upon completing the assembly.
Note that if you have used any spare, the final count may vary.
⬢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
