The cables of the heater need to be connected to the lowest screw terminals on the electronics as shown above. Here the colour coding also doesn't matter. The fan cables go onto the middle screw terminal. Here the polarity is IMPORTANT. Connection of the x end-stop For the end-stops we take a three-wire cable with the plugs on both sides. Plug the cable into the end-stop, with the marked side pointing to the back, and guide it in a small loop to the side of the printer and then down to the electronic. Make sure the cable has enough space, so the z-axis can move completely up and down. On the electronics, plug the cable into the rightmost socket, as shown in the image above. Make sure the marked side of the cable points to the USB plug of the electronics. Page 61/ 67

62 Connection of the x end-stop to the electronic The end-stops are protected against reverse connection. So if the cable is plugging in the wrong directions, you can easily correct it later. Connection of the z end-stop Connect another three-wire cable to the z end-stop and guide the cable down the vertical rod and plug it into the electronic like the red cable shown in the picture above. Make sure to plug it into the correct socket. There is always on free row of pins between the end-stop plugs. Again make sure the marked side of the cable points to the back of the endstop and on the electronic to the USB plug. Page 62/ 67

63 Connection of the y end-stop For the last end-stop we again use a three-wire cable and connect it to the end-stop. Make sure the marked side points to the back of the end-stop. Guide the cable along the side of the printer till you get to the middle rod. From there guide it below the printer, alongside the middle rod, to the electronic. Connection of the y end-stop to the electronic Page 63/ 67

64 Connection of the end-stops to the electronic Connect the cable to the electronic as shown in the picture above. Again make sure to use the correct pins for the plug and that the marked side of the cable points to the USB plug. Connection of the heated print bed If you have the deluxe set, guide the cables of the heated print bed to the electronics as it is shown in the picture above. Make sure that the y-axis can still move over its full range without any problems and that the cables don't entangle with the belt. Connection of the heated print bed to the electronics Page 64/ 67

65 The thermistor of the heated print bed gets plugged into the electronics as shown above. The heating cables are connected to the upper screw terminal of the electronic. For both cables the colour coding is not relevant. Adding the heat sinks Take the 4 heat sinks and apply a bit of heat thermal glue to the bottom of them. Then place each heat sink onto one stepper drive and make sure to leave the potentiometers accessible. Connection of the power supply to the electronic Page 65/ 67

66 Step 5.4 (optional) Needed parts for step 5.4 The following parts are needed for this step: 1x Fan 30 x 30 mm 1x Screw M3 x 10 mm 2x Washer M3 1x Nut M3 1x Metal-flag and the structure from the previous steps Connect the metal flag with the fan using the M3 x 10 mm screw, the corresponding washers and the M3 nut. Now bend the metal flag so that you can mount the fan beside the hotend at the bottom of the X-carriage. Connect the metal flag with one of the M4 screws of the Xcarriage and add the cables to the terminal block of the primary fan.

67 DANGER Make sure that the power supply is not connected to the life power while doing the following steps. Connect the ATX adapter with one thick two-wire cable with the right screw terminals marked 12V/5A on the electronic. Make sure the colour coding is correct, and you don't connect plus with ground. At the ATX adapter the cables go to the contacts marked with 12V and GND. If you have a heated print bed, you also need to connect additional cables from the power supply to the terminals marked with 12V/11A. For this, remove one or more molex plugs from the cables of the power supply and connect the black cables to GND and the yellow ones to plus. It is recommended to connect at least two cables each to make good contact. Also make sure that the unused red cables stay isolated good and can not make any shorts. As a last step, secure all cables with cable ties to the rods of the 3D printer and check again if all axes can move freely over their full range. It is recommended to bundle all cables of the extruder to one big bundle to reduce the likelihood of entanglement with the cables. Grease all smooth rods and the z drive rods with machine grease or oil to allow the axes to run smoothly. Before you active the electronics, you should check again all cabling, preferably by an expert.
