⬢New spool holder ( black color)

⬢Older spool holder (orange color)

⬢Heatbed-cable-cover

Both versions of the spool holder have the same functionality.

Note this part is already assembled on the Y-axis frame. This photo is just to highlight changes in the design.

⬢Older design has deeper holes for nuts with M3x18 bolts.

⬢Newer design has shallow holes for nuts with M3x25 bolts.

In case M3x25 bolts aren't included in the bag 7. PSU & HB please use bag 9. SPARE.

⬢M3x18 or M3x25 bolts (2 pcs)

⬢M3w washers (2 pcs)

⬢M3n nuts (2 pcs)

⬢Insert M3n nuts in PSU-Y-part nut traps.

⬢Using 2.5mm allen key, tie the PSU-Y-part to the PSU-cover.

⬢Return to the screws on the frame from Step 4 and tighten them as well. See the last picture.

If there is a gap, use the bolts to contract it.

⬢Guide the low voltage cables from the PSU under the threaded rods to the other side of the frame as shown in the picture.

⬢Tie the low voltage power cables to both threaded rods.

⬢Check the switch position on the side of the PSU if it's in correct position.

Correct position means that the switch is on the side with your mains voltage. (If you have 110/120 V mains [mostly America] the switch has to be on the left, if you have 220/230 V [Europe and the rest of the world] the switch should be on the right ).

You can change the switch position with flathead screwdriver.

⬢For the following step please prepare:

⬢Heatbed MK42 12V (1x)

⬢Power cable (1x)

⬢M3x10 screw (2x)

⬢M3w washer (2x)

⬢M3nN nylock nut (2x)

⬢IT IS VERY IMPORTANT to connect the power cable correctly. Before you start the assembly have a look at the pins. The one on the left with "GND" sign must be connected to the BLACK WIRE.

⬢Place the black wire above the pin with "GND" sign. Make sure you are using the rounded connector.

⬢Place the washer above the rounded cable connector.

⬢Press the M3x10 screw through all parts.

⬢Hold the screw and carefully turn the heatbed upside down.

⬢Place the M3nN nut on the top of the M3 screw and tighten it slightly.

⬢Turn the heatbed back, using pliers and Allen key tighten the screw. We need to adjust cable position in the next step, therefore do not tighten the screw too firmly.

⬢Repeat this procedure for the second (red) wire.

⬢BLACK wire must be connected to the "GND"

⬢RED wire must be connected to the "VCC"

⬢The cable cover, which will be applied later requires the connectors to be slightly inclined towards each other. Press them gently, but leave a gap between them.

⬢Now, tighten both screws using the Allen key and the pliers.

⬢Insert M3n nuts in the printed part.

⬢In case you can't press the M3n nut in, don't use excessive force. Take the M3 bolt and thread it from the opposite side of the printed part, as you tighten the screw, it will pull the nut in. Be careful not the break the printed part during tightening.

In case the power cable is fixed by screws (not soldered) the heatbed-cable-cover slightly differs from the picture, but the following assembly process is identical.

⬢Place the heatbed-cable-cover on the heatbed to cover the soldered cables and LED.

⬢Tighten the cover to the heatbed using M3x10 screw and Allen key. Be careful not to pinch (break) any wires from the heatbed!

⬢Guide the black thermistor cable next to the heatbed heater cable and wrap it few times around (see the photo).

The thermistor cable is in black or white colour, their functionality is the same.

⬢Use the textile sleeve and wrap the cables from the heatbed. Start by few centimeters of the sleeve behind the heatbed cover.

⬢When the first "wrap" is ready, slide it inside the heatbed cover. Ensure it is at least 5-6 mm.

⬢Before you continue with wrapping the sleeve, we need to fix it in the cable cover. Please proceed to the next step.

⬢Place second part of the cover on the top of the textile sleeve.

⬢Insert two screws M3x10 and tighten them, proceed with caution and tighten both screws equally.

⬢Your tightened cover should look like the last picture.

⬢Using 2mm allen key, tighten the heatbed to the Y-carriage.

⬢Tighten the Y-belt holder to the heatbed using the supplied 2.5 mm Allen key.

Make sure that the M3x12 screws are screwed into the heatbed and no space is left between the nut on the heatbed and the Y-carriage.

⬢If you have the Y-belt-holder with a slot, make sure that the screws are in the middle as shown in the picture.

⬢M3x8r screw (1 pc)

⬢M3 nut (1 pcs)

⬢Lead the black thermistor cable under the heatbed heater cable and wrap it few times around (see the photo).

Note the black cable from the heatbed can be also in white version, however, their function is the same (see the second photo).

⬢Take the piece of filament that came with the parts ( length around 30 cm ).

⬢Push it all the way down in the filament holder hole in the heat bed cable cover. If you experience difficulties when inserting the filament use pliers to make a sharp tip on the filament.

The filament is for whole harness support. Don't cut it, it'll go all the way with the wires to the electronics.

⬢Make sure the filament is pointing to the right while the cable holder is oriented upwards (see the nut)

⬢Tighten the part to the heatbed using 2 mm Allen key. Be careful not to pinch (break) any wires from the heatbed!

⬢Use the spiral wrap and wrap the cables from the heatbed including the NYLON. Start by one or two wraps 1 cm behind the heatbed cover.

⬢When the first wrap is ready, slide it inside the heatbed cover.

DO NOT cut the filament, you'll need the full length.

⬢Place a zip tie around the heatbed holder to tighten the spiral wrap with cables. There is a channel around the cover designed for the zip tie.

⬢Cut the remaining part of the zip tie and continue with wrapping the spiral wrap.

⬢Take a look on the printer from the top side and make sure that lines on heatbed are perfectly parallel with the X axis rods as shown in the picture.

⬢If they are not in parallel position, use 17 mm wrench to adjust the M10 nuts to get it correct. Use nuts only on the side close to left Z axis motor.

⬢Assemble the spool holders to the top of the frame as shown in the picture.

⬢To properly assemble the spool holder, let the "tooth" sit on the frame and then press in the direction of the arrows (rotate backwards, while slightly pressing downwards).

⬢Don't try to assemble spool holder by pushing it only from the top. More force is needed and you may damage the holder.

⬢Almost there! You're one step away from finishing! Continue by connecting the electronics in the next chapter - 8. Electronics assembly
