Step 1 Tools necessary for this chapter

⬢2.5mm Allen key for M3 screws

⬢2mm Allen key for nut alignment

Bag with fasteners for the LCD is usually taped to the LCD.

Step 2 Preparing the LCD parts

⬢For the following steps, please prepare:

⬢LCD-cover (1x)

⬢LCD-knob (1x)

⬢LCD-support (2x)

⬢LCD screen (1x)

⬢M3x10 screw (6x)

⬢M3nS nut (4x)

⬢SD card (1x)

Step 3 Checking the LCD cables

⬢Before you start, please ensure the cables are plugged in the correct order.

⬢To the slot called EXP1 (see the board) must be connected cable with ONE black stripe.

⬢To the slot called EPX2/EXP2 (see the board) must be connected cable with TWO black stripes.

There is an updated version of the LCD connectors, which are now connected perpendicular (90°) to the board. Functionality remains the same. See the second picture.

The board (PCB) can be red or blue, their functionality is the same.

Step 4 Assembling the LCD supports

⬢Prepare the LCD controller and LCD-support printed part as shown in the picture.

⬢Slide the LCD-support parts on the LCD-controller.

⬢Repeat the steps above for the second support.

Ensure the correct orientation of parts and the LCD controller.

The exact position will be adjusted later, no need to worry at this moment.

You can now remove the protective foil from the screen. Don't throw it away, we will reapply it soon.

Step 5 Assembling the LCD-cover

⬢Press the LCD controller with the LCD-support into the LCD-cover as shown in the picture. Be careful, there is a control knob on the other side!

⬢Adjust the position of the supports if needed.

⬢Press it as deep as possible.

⬢The LCD controller must click under support in the centre of the LCD-cover.

Reapply the protective foil on the screen, make sure foil is clean without any particles or you might scratch the screen.

Step 6 Securing the LCD controller

⬢Using the 2.5mm Allen key and two M3x10 screws, secure the LCD controller in place.

Step 7 Preparing the supports for assembly

⬢Place four M3nS nuts in the prepared slots, all the way in.

Check the proper alignment with Allen key.

Step 8 Mounting the LCD display onto the printer

ATTENTION!!! In case you haven't assembled the anti-vibration feet yet, the front part of the printer will be resting on the mounted LCD. Apply the feet now or be very careful as you might damage the LCD holder. For assembly head back to Chapter 2 (Y-axis).

⬢Locate the holes for M3 screws on the front plate.

⬢Press through four M3x10 screws.

⬢Place the LCD assembly onto the front side of the Y-axis.

⬢Tighten all four screws.
