⬢Grasp the Boost board by the edges and slide it slightly tilted onto the Boost holder so that the PSU connector goes through the opening in the metal sheet.
Do not place the Boost board on the Boost board holder yet! It sticks to the thermal pad and you will no longer be able to move the board easily.
⬢Align four screw holes on the Boost board against the columns on the Boost board holder and lay the Boost board onto the holder. Check from the other side that the PSU connector fits properly into the opening.
⬢Secure the Boost board to the holder with four M3x5 screws. Do not overtighten the screws! You may crack the electronics board.
⬢Insert the M4x8 screw into the Heatsink holder lock.
⬢Look from above through the print display hole. Place the Heatsink holder lock to the left side next to the UV LED fan. Ensure the correct orientation of the part. The narrower section of the part must be facing the back of the printer. Tighten the M4x8 screw.
Make sure to place the Heatsink holder lock correctly and maintain its orientation while tightening the screw. It must be exactly parallel to the electronics holder (metal sheet) on the left. This is CRUCIAL!
⬢Attach the M4x5 screw on the right side next to the UV LED fan. Two turns are enough for now. Don't tighten the screw all the way in!
⬢Insert the M3x18 screw into the heatsink holder, like in the picture. Just start the thread so it doesn't protrude on the other side - it must sit flush or recessed with the backside. See the second picture.
⬢Place the UV LED assembly so it touches the bottom plate by its back side. Keep it slightly tilted and press backwards until you align the "keyhole" on the heatsink holder (metal sheet) with the M4x5 screw head on the bottom plate.
Make sure the cables are not pinched!
⬢Push down until the screw head goes through the "keyhole" in the heatsink holder.
⬢Tighten the M4x5 screw in while maintaining a slight frontwards force onto the UV LED assembly with your other hand at the same time.
⬢From the front bottom left corner of your printer, tighten the M3x18 lock screw. Make sure the UV LED assembly sits flush all the way with the printer bottom plate. You can help it a little bit by pushing it downwards. Avoid touching the lenses.
⬢Look from the left below the touchscreen to inside the printer.
⬢Move the connecting rod manually up and down several times and check if the connecting rod doesn't hit the heatsink. Then move the connecting rod to the upper position. The position of the shaft should be as shown.
⬢Take a closer look at the connecting rod and check the correct alignment of the UV LED assembly:
⬢Incorrect alignment: The connecting rod hits the UV LED assembly. There is no gap between both parts. Loosen the lock screw and the UV LED assembly. Go to Securing the UV LED assembly and repeat the whole procedure again. Keep in mind that you must move the assembly a few millimeters toward the back of the printer to create a gap between the connecting rod and the heatsink and prevent them from colliding.
⬢There are two ways to mount the adapter. It depends on the version of the electronics holder in your printer.
⬢Take a closer look and compare with the pictures. Then choose the appropriate instructions:
⬢NEW DESIGN: There are two threaded columns on the electronics holder. The threads are visible in the middle and right screw holes in the electronics board. Follow these instructions: Installing the LCD adapter spacer (NEW)
⬢OLD DESIGN: There is one threaded column on the electronics holder. The thread is visible in the left screw hole in the electronics board. Follow these instructions: Installing the LCD adapter spacer (OLD)
