Start on the front side of the printer and tie together cable from the tilt motor and right blower fan.
Continue on the right side and the cables from the PSU (power + power panic) to the bundle.
Don't pull the cables, also don't over-tighten the zip tie.

Use the cardboard and place the back of the printer on it. Make sure the PSU power button isn't touching anything.
Gently pull the cables out and place zip tie around them near the right edge of the circular opening.
Use another zip tie on the other side.
Put the cable bundle back inside the printer, make sure it is all the way back and won't interfere with the UV LED, which will be mounted to the circular opening in the upcoming steps.
That is all for now regarding the cable management, we will continue later on in this chapter.

WARNING: After you remove the cover from the UV LED, please avoid touching the diodes. Any dirt or grease on the surface might result in print artefacts.
UV LED is protected with a plastic cover. To remove it, push it down, then pull slightly in the indicated direction and remove it.
While connecting the UV LED cable proceed carefully. The cooling fins are sharp, you can hurt yourself.
Connect the UV LED cable. Make sure the safety pin on the connector "clicks" in the UV LED.
Check all the wires are all the way in the connector.
Connect the UV LED fan cable extension. Make sure both cables are properly connected.

Step 9 Mounting the UV LED assembly

Slide the cover on the printer and secure it on one side using two M3x5b countersunk screws. Don't tighten them firmly and move on the other side, repeat the procedure.
As soon as the cover is aligned and partly secured, add the remaining screws and tighten them all.
Tighten carefully, if you can't reach the holes in the printer, realign the cover.

Step 36 Preparing resin tank parts

以下のステップに向けて、下記の部品を用意してください。
Resin tank (1x)
Resin tank frame (1x)
Resin tank screw (2x)
M4x8rt Torx screw (22x)
FEP film (1x)

Step 38 FEPフィルムの準備

FEPフィルムの準備
FEPフィルムの準備
FEPフィルムの準備
WARNING: the following procedure is crucial. Make sure you read the instructions first! The FEP film consists of three layers. Two layers are for the protection of the middle layer, which is the actual FEP film.
Separate all layers slightly apart to recognise them:
Semi-thick outer layer (protection)
Thick inner layer (FEP film)
Thin outer layer (protection)
FIRST, remove completely the SEMI-THICK outer layer. Make sure all the circular holes are free of the remains of the film.
Only after you have successfully removed the thick layer and the "circular" remains, remove the THIN outer layer.
You should end up with the middle layer, which is without both outer layers. Also, double-check you have removed all the remains.

Step 40 Inserting the torx screws

Check the holes in the frame and in the foil are aligned.
DON'T PUNCH through new holes for the Torx screws!
Start inserting the remaining screws. Don't push hard, or you might bend the frame.
Check you have used twenty-two M4x8rt Torx screws.

Place the frame with the film and screws on the tank and start tightening M4x8rt screws with the Torx tool. Follow the indicated direction, tighten one by one. Screw them only halfway in!
Reseat the parts if needed and tighten the screws, this time just near the surface.
Final tightening of the screws, but BE CAREFUL. If the Torx tool slips, you might damage your FEP film.
Pro tip: Turn the tank upside down to its "normal position" and fill it with tap water to its max level. Watch the tank and ensure no water is leaking.

Step 42 レジンタンクの取り付け

Take any knife with a sharp tip (not included in the package).
Carefully punch two holes in the FEP film, as indicated in the picture.
Punch each hole in two directions to create a cross.
Don't use a knife with a blunt tip or you might accidentally overstretch the FEP film.

Slide the lid all the way in and tighten the screws in the hinges to secure it (use 4mm Allen key). Don't over-tighten the screws or you might crack the lid.
Try closing the lid, in case you will find any significant gap, reseat the cover or the hinges.

Step 46 Returning the print platform

Returning the print platform
Slide the print platform back in and secure it using the knob.
The platform is now still able to move (wobble on the cantilever), it is ok. Final tightening will be done during the calibration process by adjusting the marked screw(s).
