For this guide, please prepare:
2.0mm Allen key
Cardboard or similar soft pad (e.g. a piece of cloth)
Owners of the SL1 kit version can use the cardboard pad that came in the kit.

Step 3 Preparing the printer

Preparing the printer
For a better handling, it is recommended to prepare a clean workbench with a space of at least 1 m x 1 m (40 in x 40 in).
We're recommending a bright light above your workbench. Some parts inside the printer are dark and inadequate light could make a very difficult procedure.
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.
Remove the print platform
Turn the printer off and unplug it.
All the removed screws will be reused. Do not throw away any screw! In the instructions, it is graphically showing which type of screw to prepare.

Step 4 Securing the printer

Place the cardboard or other soft pad on your workbench.
VERY CAREFULLY lay the printer on the soft pad by its back.
Make sure there is a gap between the PSU power button and the surface beneath it. Avoid laying the printer directly on the button.

Make sure you do not pinch the cable by making sure that the cover is flush with the surface of the printer.
Align the holes after closing the UV LED fan.
Secure the UV LED fan by tightening eight M3x5b countersunk screws, that you removed earlier.

Now you can carefully put the printer back on its feet.
Plug the printer and turn it ON.
On the touch screen navigate to Home -> Settings -> Calibration -> Selftest.
