⬢Zip tie (3x)

⬢Cardboard or similar soft pad (e.g. a piece of cloth)

⬢3.0mm Allen key for units shipped until July 2019

⬢4.0mm Allen key for units shipped between July - August 2019

⬢Bowl or box for the screws - keep all removed fasteners for later use

ESD gloves are anti-static (prevent damage to the electronics).

⬢Turn the left side of the printer towards you.

⬢Locate, release, and remove four screws.

⬢Turn the printer to the other side (180 °) and again remove four screws.

⬢Slide the cover just a few cm/inches out.

⬢Use any soft pad (e.g. a towel) and place the back of the printer on it. Make sure there is a gap between the PSU power button and the surface beneath it. Avoid laying the printer directly on the button. Kit owners can use the cardboard.

⬢Release all screws on the UV LED assembly.

⬢Carefully put the UV LED assembly out of the printer. Do not disconnect it.

⬢Carefully cut both zip ties on the cable bundle.

⬢Carefully cut the zip tie on the cable from the tilt motor and right blower fan.

The blower fan is part of an assembly (fan + metal sheet + printed part). Let's remove it as one piece and disassemble it to parts later on.

⬢Carefully push out the fan cable from the electronics to the right blower.

⬢Release the first screw on the support.

⬢Hold the blower fan assembly with one hand.

⬢Use the other hand to release the second screw on the support.

⬢Remove the blower fan assembly.

⬢Release and remove two screws from the front side of the blower fan.

⬢Remove the blower (printed part).

⬢NEW version: Release and remove two screws M3x20r from the front side of the blower fan.

⬢OLD version: Release and remove two screws M5x10r from the backside of the blower fan holder.

Some old versions might be with two M5x16r screws and two black screws M4.8x22.

⬢New right blower fan (1x)

⬢Blower (1x)

⬢New blower fan holder (1x) with columns

⬢New blower gasket (1x)

The list continues in the next step...

⬢Use isopropyl alcohol (IPA) and paper towel to clean the surface of the fan (the side with the turbine), before you apply the gasket.

⬢Remove the centre part of the gasket, you will need just the outer "rim".

⬢Peel off the protective film (paper).

⬢Place the gasket on the fan as in the picture, with the glue facing down. Press it all around to ensure full contact between the gasket and the fan.

⬢Place the fan and the fan holder like in the picture. See the arrows to ensure the correct orientation of the fan.

⬢The left side is of the fan.

⬢The ride side is of the fan.

⬢Guide the cable through the hole.

⬢Place the fan on the columns and slide it carefully all the way down. Try to push equally to ensure the fan is always levelled.

⬢Secure the fan using two M3x20 screws. Tighten them very carefully, or you might break the fan's casing.

If you had the old version of the blower fan holder (without columns), the Mx20r screws are included in the replacement set.

⬢Make sure that both square nuts are still inserted in the blower.

⬢Rotate the fan assembly like in the picture and assemble the blower from the top, while:

The assembly must be smooth, don't apply unecessary force or you will break the fan or the printed part.

⬢Once the blower is seated, ensure there is no visible gap or deformation.

⬢To mount the blower, turn the assembly carefully around and secure it with the M3x5 screws.

⬢Insert the fan assembly inside the printer. The metal sheet (fan holder) has to be behind the support.

⬢Hold the fan assembly with hand and secure with the M3x10b countersunk screw to the right screw hole.

⬢Insert and tighten the second M3x10b countersunk screw to the left screw hole.

⬢Guide the fan cable from the blower through the space under the electronics.

⬢Connect the cable to the electronics.

⬢Tie together cable from the tilt motor and right blower fan on the front side of the printer.

⬢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.

⬢Insert the UV LED assembly back into the printer. Orientation as shown in the picture. Be careful not to pinch the cables!

⬢Mount the UV LED assembly with eight M3x5b countersunk screws.

⬢Now you can carefully put the printer back on its feet.

⬢Slide the cover half-way to the printer and stop, we need to connect the front USB and power button first.

⬢NEW DESIGN: Look from above in the front cover and connect the USB & Power cable. Make sure the safety pin "clicks".

⬢OLD DESIGN: Connect the power cable button to the extension cable. Make sure the safety pin "clicks".

⬢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.

⬢Turn the printer over (180 °) and use the same procedure.
