⬢For the following step please prepare:

⬢Heatbed MK52 24V (1x)

⬢Power cable (1x)

⬢M3x10 screw (2x)

⬢M3/3,2/9/0,8 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.

Design of your heatbed might slightly differ from the last picture.

⬢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.

⬢Push the Y-carriage to the front and place the Heatbed behind.

⬢Locate a hole the centre of the Y-carriage.

⬢Place one spacer on the top of the hole.

The exact position of the spacer will be adjusted in the next step.

⬢Push the Allen key through the middle hole on the Heatbed and place it above the spacer. Use the Allen key to align all parts.

⬢After the alignment insert the M3x12b(14b) screw instead.

⬢Tighten the screw just slightly.

⬢Move to the right side of the heatbed.

⬢Place another spacer with the pliers.

⬢Push the pliers between the heatbed and the Y-carriage.

⬢Use the Allen key to align the spacer.

⬢After the alignment insert the screw instead and tighten it slightly.

⬢Using pliers insert spacers and screw into the remaining holes. DON'T fully tighten the screws.

⬢After all screws are in place, tighten them in the following order:

⬢Center screw

⬢First four screws (edges)

⬢Last four screws (corners)

⬢Locate four mounting points on the YZ frame.

⬢Place the PSU on the frame and secure it with the M4x10r screws. Don't tighten them completely.

⬢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.

⬢Look for the Einsy-base in your kit and compare it with the pictures, there are two options:

⬢Your package contains the B7/R3 design, which has removable a part for the RPi Zero W. Please proceed according to the: 8. Electronics assembly (B7/R3 design)

⬢Your package contains the B3/R2 design without the removable cover. Please proceed according to the: 8. Electronics assembly (B3/R2 design)
