11. Installation of the Heatbed

(1) 2.0x75mm Hexagonal Screwdriver

(2) 2.5x75mm Hexagonal Screwdriver

(3) 5.5 x 125mm Nutdriver

(4) PH2 Screwdriver for Phillips Screws

(5) Lighter

(1) MK52 Heatbed

(2) Heatbed Cover Bottom

(3) Heatbed Cover Top

(4) Cable Holder Angled

(5) 32cm Techflex-Cable Tube (Diameter 6,4mm)

(6) 34cm Nylonfilament

(1) 2x M3 Nuts

(2) M3 Self-Securing Nuts

(3) 9x M3x12mm Countersunk Screws (silver)

(4) 2x M3x14mm Hexagon Socket Head Cap Screws

(5) 3x M3x16mm Flat Head-Head Socket Cap Screws

(6) 9x Heatbed Spacers

Insert 2x M3 Nuts into the holes provided in the lower heatbed cover.

Shorten the Techflex tube to a length of 32cm. Briefly heat the two ends with a lighter.

Shorten the nylon filament to a length of 34cm and push it through the Techflex tube.

Now, push the heatbed cables and the heatbed thermistor cable through the Techflex tube.

Place the Heatbed Cover Top on the cables on the heatbed and fasten it with a M3x16mm Countersunk Screw (silver).

The screw is fastened from below with a M3 Self-Securing Nut.

The installation of the M3 Self-Securing Nut can be made easier with the use of a socket wrench (5.5x125mm).

Make sure that about 1cm of the nylon filament sticks out at the end.

Slide the Techflex tube and the nylon filament under the cover.

Place the Heatbed Cover Bottom onto the Heatbed Cover Top and ensure that the thermistor cable is routed through the slot in the Heatbed Cover Bottom.

Now fasten the Heatbed Cover Bottom with 2x M3x16mm Countersunk Screws (silver).

Be careful not to pinch the thermistor or the Techflex tube.

Pull the y-carriage to the front of the frame.

Place 9x Heatbed Spacers on the threaded holes in the y-carriage.

Carefully place the heatbed on the spacers. Then, check the positions of the spacers under the heatbed.

Using 9x M3x12mm Countersunk Screws (silver) loosely'' fasten the heatbed to the y-carriage.

Now, place a long straight object, (e.g. a ruler or an aluminum extrusion) between the z-stepper motor and the z-profile on the heatbed (see Fig. 1).

Press the selected object against the front of the z-profile and use the lines on the heatbed to check whether it is aligned straight.

When the heatbed is aligned straight, tighten the 9x M3x12mm Countersunk Screws (silver).

If the heatbed can not be straightened even by turning it slightly, you must unscrew it again and realign the underlying y-carriage (see manuals 03.1. / 03.2.).

Place the end of the Techflex tube, with the heatbed cables and heatbed thermistor, into the lower cable guide on the left side of the Einsy Box.

Fix the cable tube with an angled cable holder and 2x M3x14mm Hexagon Socket Head Cap Screws.

Attach the heatbed cables to the two right connections using the PH2 Phillips screwdriver (see Figure 2).

Plug the heatbed thermistor into the right one of the three connectors.

The heatbed is now fully installed.
