⬢Rambo-cover-hinge top
⬢Rambo-cover-hinge bottom
Casing parts can slightly differ from pictures.
⬢Insert M3n nuts (4 pcs) in nut traps.
⬢Insert M3nS (1 pcs)
⬢M3x10 screws (2 pcs)
⬢In the next step, use highlighted holes.
⬢Slide X-axis cables through the Rambo cover while attaching the Rambo cover base to the frame as shown in the picture.
⬢The spiral wrap must run into the Rambo cover so it is held in place when tightened up.
⬢Tighten the Rambo cover base to the frame using supplied 2.5 mm spanner.
⬢In the next step use the highlighted hole.
⬢Tighten Rambo cover hinge bottom to the frame using one M3x10 screw and supplied 2.5 mm Allen key.
⬢M3x10 screws (4 pcs)
⬢Slide the electronics into the Rambo cover base and secure the board in place using M3x10 screws.
Note the correct orientation of electronics and the Rambo cover base.
⬢X-axis motor
⬢Y-axis motor
⬢Z-axis motors (the order of Z-motors doesn't matter )
⬢X-axis endstop
⬢Y-axis endstop
⬢Low voltage main cables (wires going out from PSU)
All motor cables have their marking for easier assembly.
Connect cables and arrange cables as shown in the picture. Check all connectors are properly plugged!
⬢Guide the cables from the heatbed through the bottom hole of the Rambo cover base.
⬢Push the filament all the way down through the filament holder hole in the Rambo cover base.
⬢Using a ziptie, tie the cables from the heatbed to the Rambo cover base at the end of the spiral wrap.
Ensure the heatbed connector is plugged correctly and all the way in.
Double check the zip tie is tied firmly, there is a lot of movement.
⬢Guide the cables from the extruder through the upper hole of the Rambo cover base.
⬢Push the filament all the way down through the filament holder hole in the Rambo cover base.
⬢Using a ziptie, tie the cables from the extruder to the Rambo cover base at the end of the spiral wrap.
⬢P.I.N.D.A. probe
⬢Extruder motor
⬢Heatbed heater
⬢Extruder heater
DOUBLE CHECK the connection! It is so important to ensure the correct connections.
⬢Extruder thermistor (cable going from the extruder labeled with Yellow/Green heat shrink) [Orientation does not matter]
⬢Heatbed thermistor (white or black cable going from the heatbed)
⬢Print fan (cable going from the extruder labeled with Red heat shrink)[make sure that the red wire is closer to the thermistor]
⬢Extruder fan (cable going from the extruder labeled with Blue heat shrink)
DOUBLE CHECK the connection! It is important to ensure the correct connections!
⬢LCD cable with ONE stripe (Connector P1)
⬢LCD cable with TWO stripes (Connector P2)
Make sure that the key of connector is matching the key on the electronics.
⬢Check your electronics connection with the attached picture.
⬢In the next step use the highlighted hole.
⬢M3x10 screw (1 pcs)
⬢Rambo-cover upper hinge
⬢Insert M3x10 screw into the hinge.
Move the heatbed all the way towards the LCD for easier access.
⬢Assemble the Rambo-cover doors on the lower hinge attached to the frame and slide the upper hinge in place.
⬢Secure the upper hinge to the frame.
⬢M3x40 screw (1 pcs)
⬢Close the Rambo-cover doors
Make sure that no wire is pinched!
⬢Tighten M3x40 screw.
⬢Congratulations, you've just assembled the whole Original Prusa i3 MK2 3D printer!
⬢You're almost there... Just finish the chapter 9. Preflight check [進行中の翻訳]
