⬢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 Input cover into the opening in the back plate from the inner side. See the correct orientation of the part. The circle hole must be on the left.
⬢Check from the other side that the surface with the plastic part and the back plate are aligned. If not, slightly and evenly push on the plastic part from the inner side of the printer.
⬢Insert the M3x5 screw into the backplate. Do not fully tighten the screw, leave a 3mm gap between the screw head and the surface. We will tighten the screw later.
⬢Connect the power cable into the slot at the bottom of the boost board.
⬢Connect the thermistor cable into the upper slot on the top left corner of the boost board.
There are two color variants of the thermistor cable. Your printer may have a black-and-white or black-and-red cable. However, their function is the same.
⬢Connect the Boost motion cable (labelled "M") to the lower slot on the Boost board. Connect the unmarked side of the cable (without the yellow label) to the Booster board.
⬢Connect the Boost A64 cable (labelled "A") to the upper slot on the Boost board. Connect the unmarked side of the cable (without the yellow label) to the Boost board.
⬢Guide both cables behind the cable bundle through the gap under the electronics holder out of the printer.
⬢Disconnect the thermistor cable (black and white wires) from the electronics board.
There is a safety lock latch on the bottom side of the connector. Do not pull the cable before pressing the lock latch.

⬢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!
⬢Move the cable bundle backward as much as possible while being gentle to it. Do not push hard! The whole bundle should go to the furthermost possible position.
⬢Make sure there are no cables in this area.
⬢In some units, an optical sensor cable may guide this way. If the cable guides over this location in your printer, follow the next step.
⬢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.
⬢Look from the electronic side and make sure there is no gap between the base and the heatsink holder (metal sheet). It needs to sit flush against the bottom.
⬢Slide the LED assembly to the front of the printer. Make sure it moves evenly on both sides. Use reasonable force.
⬢The screw on the right side should slide easily into the oval groove.
⬢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.
⬢UV LED cable (1x) you already have from the previous chapter
Note: The appearance of the UV LED cable may differ. It depends on the printer version. However, both of its connectors are the same in all versions.
⬢Take a closer look inside the printer behind the touch screen. There is a flat connector on the UV LED assembly. You will need it in the following step.
⬢Connect the big white plug and the UV LED assembly together. The white plug slides onto the flat connector of the UV LED board. Make sure the lock on the white plug is on the top.
⬢Slide the white plug on until you feel it click. Try pulling the white plug lightly to make sure it holds in place.
⬢Check that the lock on top fits the hole properly. That was the click you felt.
⬢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)
⬢Insert the M3x8 screw into the right hole on the LCD adapter.
⬢Place the 6BA washer on the screw.
⬢Connect the adapter to the slot on the electronic board. Make sure it fits on the LCD adapter spacer and then secure it by tightening the screw. Do not overtighten the screw, you may crack the board!
Make sure the washer doesn't fall off the screw!!!
⬢Slightly press the adapter to make sure it is connected correctly.
