Before you start, do the following:
⬢Move the cantilever with the print platform up (Menu -> Control -> Home platform). You will need more space in the following steps.
⬢Remove the resin tank. If you have a resin inside, pour it back into the bottle and clean the tank.
⬢Turn the printer off and unplug it.
⬢Use ESD gloves (recommended).
ESD gloves are anti-static (prevents damage to the electronics).

⬢Slide the cover just a few cm/inches out.
There are two designs of USB and power button:
⬢NEW DESIGN: The USB and the power button share the same connector. Disconnect the cable and remove the cover completely.

Keep the orange protective sticker on the other side of the print display for now!
⬢Make sure the cable from the display is not bent or pinched before you tighten up the screws. The cable can be damaged easily by improper handling. Keep an eye on it.
⬢Carefully insert the display assembly into the printer, as seen in the picture. Make sure the cable is ON THE LEFT side under the black tilt frame and moving freely.
⬢Carefully align the display with the tilt frame underneath. Use the M4x14b countersunk screws to fix it back in position.
⬢Now, tighten all 4 screws gradually in a cross-pattern using a reasonable force.

WARNING: screen cables and connectors are fragile. Please proceed with extra caution.
⬢Make sure the safety latch is still open.
⬢Carefully insert the display cable into the connector. The white line on the cable must be aligned parallel to the connector.
⬢Align the cable into the connector so that the "tooth" on each side of the cable fits into the shaped slot.
⬢Close the safety latch using your finger.
⬢Verify that the white line on the display cable is slightly above the safety latch, and it's parallel to the connector body.

⬢Plug in the printer and turn it ON.
⬢On the touchscreen navigate to Menu -> Settings -> Calibration -> Display test and follow the instructions on the display.
Don't open the lid under any circumstances, keep it closed! There is a UV light inside, which will cause damage to your eyes.
⬢Look from the front side into the printer. Your eye level needs to be slightly above. Otherwise, you won't be able to judge the result correctly.
⬢Check the entire screen, you must be able to see the details of our company logo across the whole screen. No parts (letters) should be missing.
Tip: If you can't see the logo clearly, try placing a sheet of paper onto the screen. We recommend format A5 with a density 80g/m².
Don't forget to CLOSE THE COVER after inserting the sheet!
