Different heatbed cable covers
Different heatbed cable covers
Starting mid of January 2018 we are shipping redesigned heatbed cable cover. See the picture to recognize your version and then select from the following:
New design: start with the Step 3
Old design: start with the Step 11
Extra fasteners needed for the redesigned heatbed cable cover are included with the printed part.
Preparing the heatbed (new design)

For the following steps, please prepare:
Heatbed MK52 (1x)
Spiral wrap (1x)
There are two spiral wraps remaining, use the bigger (thicker) one. You have to fit inside more cables now.
M3n nut (3x)
M3x10 screw (3x)
Heatbed-cable-cover (1x)
NYLON filament 30cm (1x)

Using the pliers cut one end of the filament to create a tip.
Check the tip is similar to the third picture.

Push the filament in the hole in the heatbed-cable-cover.
BE EXTREMELY CAREFUL as the pliers tends to slide and you can easily harm yourself or break the printed part!!!
To make your assembly easier, check the filament is curved up (as in the picture).
If you have issues, try to adjust the tip on the NYLON filament.

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.

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!

Do not stretch the black/white thermistor cable, leave some slack under the heatbed, so when the heatbed moves during print, the cable won't get stretched resulting in disconnection from the centre of 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 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. Ensure it is at least 5-6 mm.
Continue with wrapping the spiral wrap.
DO NOT cut the filament, you'll need the full length.

Place second part of the cover on the top of the spiral wrap.
Make sure the thermistor cable is in the middle going through a cutout in the printed part!!! Otherwise, you will pinch and possibly break the cable!!! (see the first picture top left corner)
Insert two screws M3x10 and tighten them, proceed with caution and tighten both screws equally.
Don't tighten the screw completely on one side and then on the other (see the second picture)!
Your tightened cover should look like the last picture.

Place a zip tie around the heatbed cover to tighten the spiral wrap with cables. There is a channel around the cover designed for the zip tie.
Tighten the zip tie, but do not overtighten it! You might pinch (break) the heatbed wires. It should be snug around the stem of the cover, enough to hold the wrap in place.
Cut the remaining part of the zip tie.
Preparing the heatbed screws and spacers
Preparing the heatbed screws and spacers
For the following steps, please prepare:
M3x14b screw (9x) / M3x12b screw (9x)
Due to update in manufacturing process, your kit might come with 12mm screws instead of 14 mm. Functionality remains unchanged.
6x6x3t spacer (9x)

Slide the PSU holders under the PSU cover.
Secure the PSU with two M3x10 screws. Don't tighten them completely. You want to be able to move the PSU on the mount to properly line up the other mount.
Re-seat the PSU and then tighten all four screws.
Heatbed and PSU are done!
Heatbed and PSU are done!
Getting closer! Just one more chapter and the assembly is done!
Check the final look, compare it to the picture.
Ready for next chapter? Lets move to 8. Electronics assembly (B3/R2 design)
Don't place the steel sheet on the heatbed yet. Wait for the instructions in the Wizard during the calibration process.
