-
Clamp the extruder on the top and bottom linear bearings of the X axis
-
Make sure all cables, except hotend cables, are running on top of the bottom smooth rod (between two X smooth rods). The hotend cable should stay under the bottom smooth rod.
-
Clamp the top of the x_carriage_back
-
Secure it with two M3x10 screws in top holes. Don't tighten them right now!
-
Finish securing it with two M3x18 screws in bottom holes. Don't tighten them right now
-
Gradually tighten each of the four screws while moving the extruder. Don't over tighten them.
-
-
-
Adjust the two x_end_idler screws to to have the x_end_ilder_idle_mount flush as shown in the first image
-
-
-
Slide one end of the 2GT timing belt into the right side of the x_carriage.
-
Route the timing belt through the x_end_motor, around the pulley and back out through the x_end_motor.
-
-
-
Route the timing belt through the x_carriage.
-
Continue to route the timing belt around the idler of the x_end_ilder_idler_mount and go back in the direction of the x_carriage.
-
To finish routing the timing belt, attach few belt teeth in the x_carriage.
-
Estimate the length and cut the belt. Finish to insert it in the x_carriage
-
-
-
Join cable_guide_back_a and cable_guide_back_b together
-
Slide a M3x40 screw through them
-
Screw the M3x40 into the x_carriage
-
-
-
Create a bundle with the following cables: extruder motor, hotend fan, Pinda, and nozzle fan. Route the bundle as shown in the first image
-
Slide down the x_carriage_back with the cable bundle in the middle.
-
Secure the x_carriage_back bottom with one M3x18 screw
-
And two M3x10
-
-
-
Clip the filament sensor cables on the filament sensor connector. The white wire of the cable should face up when connected to the filament sensor.
-
Route the filament sensor cable through the channel in the x_carriage_back.
-
-
-
Using two zip ties, attach the hotend cables.
-
Insert the 3 mm nylon filament into the end of the cable_guide_back.
-
-
-
Wrap the wires coming out of the x_carriage_back using spiral wrap for 2-3 turns. The wrap should touch the x_carriage_back.
-
Continue spiral wrapping the cable now including the nylon filament and hotend cables.
-
Secure the spiral wrap to the cable_guide_back using three zip ties.
-
-
-
Finish to wrap the spiral up to the Rambo Mini / Einsy.
-
Follow the original Prusa manual to connect your extruder cables on the Rambo Mini / Einsy:
