Move the extruder carriage all the way to the right (from the rear view as shown in the figure). Carefully thread all cables through the opening of the X-plate in the direction of the Y-plate. Then engage the energy drag chain at the free end piece. Fastening the lines First, use four small cable ties (99 mm) to lay the lines from the ex- Move the extruder carriage several times from left to right. truder (heating, temperature sensor and fan) neatly to the plugs.
Tie all unused cables together with a small cable tie (99 mm). The cables for the extruder heating, the temperature sensor and the fan are also tied together with a small cable tie. Make sure, however, that the cable tie is behind the plug, i.e. in the direction of the drag chain. Push all cables behind the motor. The lines to the extruder should be at the top. Fix them to the motor cable with a small cable tie. The lines to the extruder must not be routed over the inlet for the filament.
Connection of the limit switch for the Z-direction (Z-min limit switch at the X-plate) 1 x cable 09 (Z-min limit switch) Connect the cable 09 with the side without numbering to the connection plug of the light barrier. Fasten the cable to the spacer with a small cable tie (99 mm). The cables between cable tie and connector plug must not be tensioned. Placing the line of the Z-stop Lay the cable of the upper limit switch for the Z-direction to the remaining cables of the extruder unit.
Connection of the limit switch for the X-direction 1 x line 06 (X-limit switch) Thread the cable 06 downwards through the round bore hole in the X-plate and connect it (again the side without numbering) to the connector plug of the X-limit switch. Installation of the LED strip 1 x cable 28 (LED strips with connection cable) 84 Attention! Please note the following figure first.
Stick the LED strip, as shown in the figure, from below to the X-plate, just below the guide rail. The adhesive surfaces must be degreased beforehand. Align the LED strip so that the connection cable ends at the front of the X-plate motor. Caution: The LED strip must not touch the light barrier holding block. Now continue with the previous figure.

It is best to use a small pointed pliers or tweezers first and an external hexagon socket wrench to tighten it. Carefully place the printer on the front panel. You should hold the previously inserted lower screw tight. Dismantle the foot together with the holder in the upper right corner (from the figure view). Fasten the cylinder head screw with the nut M4.
Preparation of the cables for the heated printing plate and the Y-limit switch 1 x energy drag chain small, 22 links 1 x lines 05 (heating printing plate) 1 x lines 07 (limit switch Y) 1 x lines 12 (temperature sensor printing plate) Also required: 1 x cylinder head screw M3x10; 1 x washer M3; 2 x sprocket M3; 1 x cylinder head screw M3x16 Push the cables into the energy drag chain in such a way that the end link with the holes is directed towards the cable ends without label.
Fasten the protective conductor (green/yellow cable with ring eye- Caution: This connection creates the safety-technically imlet) with the cylinder head screw M3x10, the washer M3 and the two portant contact between the housing parts and the protective sprockets M3 to the bottom side of the undertable. ground.
Connection of the Y-limit switch Pull out the cable 07 until it reaches the limit switch and then insert it Connect cable 07 to the limit switch mounted on the undertable. through the opening of the undertable. Fix the cable to the undertable with three small cable ties (99 mm). In order to lay the cable as tensioned and neatly as possible, start with the cable tie, which is closest to the limit switch, and work your way towards the drag chain. Push the remaining cable back into the drag chain.
Laying and fixing the cables on the undertable Take the printing plate and place it on the 4 spacers. If, like us, you have put the printer back on the front side, fasten the printing plate crosswise with at least 2 countersunk screws M4x10. Tie the power cable and the line for the temperature sensor of the printing plate together with two small cable ties (99 mm) (see the two upper arrows in the left figure). The cable tie closures should point upwards.

Connection of the Y-motor 1 x cables 02 (Y-motor) 92 Connect cable 02 (Y-motor) to the connector of the Y-motor. Fasten the cable to the motor using 2 large cable ties (142 mm) that have been joined together (see figure).
Route line 02 through the opening in the Y-plate upwards as well. Move the undertable back and forth several times. Then reattach the cable harness to the tension relief of the drag chain using two large cable ties (142 mm). With the cable tie, which is closer to the drag chain, you only attach the cables in the drag chain to the tension relief. Use the other cable tie to additionally fasten the cable of the Y-motor. Make sure that the cable is slightly tensioned.
Placing the energy drag chain from the Y-plate to the operating cover 1 x energy drag chain small, 25 links Push the lines coming from the opening in the Y-plate into the last remaining energy drag chain (small, 25 links) so that the end link with the nipples points at the line ends with the label. Snap the energy drag chain into the end piece on the Y-plate. Attach the cable harness to the tension relief of the drag chain end piece using two large cable ties (142 mm).

Connection of the Z-motor 1 x line 03 (Z-motor) Push the Z-motor connector through the opening in the rear panel so that it is accessible from below.
Connect the cable 03 (Z-motor) to the connector of the Z-motor. Connection of the heating for the printing plate Now connect the heating of the printing plate (line 05) first. Connect the two black wires to terminal X38 (see circle in the figure) of the main PCB. Tie both lines together with a small cable tie (99 mm) close to the connection terminal (see vertical arrow in the small figure).
Connection of the remaining device cables Now connect all other device lines to the main PCB according to the table on the next page. The figure shows how the cables should be laid. Lay all cables neatly and secure them with small (99 mm) and large (142 mm) cable ties and a self-adhesive cable tie holder. Use large cable ties (142 mm) for the cable tie holder and at the points where all control cables are combined (see arrows in figure).

Degrease the glue areas beforehand. Attach the silver warning text sign to the front of the printer below the keyboard as shown in the figure.
16. Upgrade from single to dual extruder This chapter only applies to buyers of the RF2000 v2 single extruder kit and finished device who want to upgrade their printer to 2 extruders. Accordingly, the RF2000 v2 upgrade kit for dual extruders must also be purchased. If you have purchased the kit and would like to upgrade to dual when assembling it, it makes sense to consider this chapter directly when assembling it.
Loosen and remove the two countersunk screws securing the extruder unit to the printer.
b) Preparation of various components Mounting the knurl on the 2nd feed motor 1 x actuator 1 x feed knurl 1 x threaded pin M3x5 Place the feed knurl on the axis of the actuator and fasten it with the threaded pin. Apply threadlocker varnish to the threaded pin. The feed knurl must be flush with the upper edge of the motor shaft. Assembly of the 2nd ball bearing holder 1 x ball bearing holder (right) 1 x grooved ball bearing (diameter inside/outside 3.
Assembly of the fan sheet for 4 fans 1 x fan sheet for 4 fans 1 x rod 1 x cylinder head screw M3x6 Fasten the fan sheet to the rod with the cylinder head screw. Apply a threadlocker varnish to the screw.
First attach a double fan with 6 screws and nuts on one side of the fan sheet, as shown in the figure. Leave the fan cable on the side where the fan is. The fans must be aligned so that the blowing direction (indicated by an arrow on the fan) goes downwards through the fan sheet. All screws must be provided with threadlocker varnish. 106 Now attach the 2nd double fan with 6 screws and nuts, as shown in the figure, on the other side of the fan sheet.
c) Assembly of the 2nd extruder Assembly of the heating block 1 x heating block 1 x nozzle 0.4 mm 1 x PTFE thread sealing tape Cut about 25 to 30 mm of thread sealing tape from the roll and wrap it around the thread of the nozzle, as shown in the figure. Observe the winding direction in any case! The sealing tape must run with the thread! This means that the end of the sealing tape on The heating blocks for the two extruders are identical. The the outside must not oppose the turn-in direction.
1 x heating block with mounted nozzle 1 x cylinder head screw M3x10 1 x heating cartridge Insert the heating cartridge into the corresponding opening from above (opposite of the nozzle). Secure the heating cartridge with the cylinder-head screw as illustrated. The cartridge should be flush with the heating block at the bottom of the nozzle.
The sealing tape must never protrude beyond the thread. Cut off the sealing tape that protrudes over the thread with a sharp knife, e.g. by running the knife along the upper-most groove of the thread. Smooth the sealing tape well with your fingers. The ridges of the thread may be slightly visible. This makes it easier to screw the nozzle holder into the PEEK part without the sealing tape jerking in the thread. Turn the nozzle holder into the PEEK part carefully.
Carefully turn the extruder inlet into the PEEK part and tighten it manually as far as possible. 1 x extruder upper part 1 x nut M6 (flat ISO 4035) 1 x PTFE thread sealing tape 110 Screw the M6-nut onto the long thread of the nozzle holder to the stop.
Cut about 30 to 35 mm of thread sealing tape from the roll and wrap it around the thread of the nozzle holder, as shown in the figure. Observe the winding direction in any case! The sealing tape must run with the thread! This means that the end of the sealing tape on the outside must not oppose the turn-in direction. Otherwise, it might happen that the sealing tape is shifted when screwed in and does not seal properly. The sealing tape must never protrude beyond the thread.
1 x extruder 1 x temperature sensor 1 x cylinder head screw M3x8 (flat head) 2 x paper disc M3 First check the two PTFE tubes on the temperature sensor. These must both be present at the temperature sensor (see small figure above left). If this is not the case, push them towards the temperature sensor until they are present.
