⬢Move the cantilever with the print platform up (Menu -> Control -> Home platform). You will need more free space for manipulation in the following steps.
⬢Open the orange acrylic cover and remove the print platform.
⬢Remove the resin tank. If you have resin inside, pour it back into the bottle.
⬢SL1 units have been shipped with two designs of the print display cable holder. Please take a look closer to and check what version of the plastic parts do you have. Then follow the appropriate steps:
WARNING: Be very careful while disconnecting the cable. You might damage both the cable and the board!
⬢Release and remove the M3x8 screws. Keep them for the reassembly.
⬢Remove the display cable holder.
⬢GENTLY pull the cable closest to the "silver rectangle" to disconnect the connector from the board. If possible you can use your nails to push the connector out. Don't use any tools like pliers or screwdrivers.

⬢Release and remove two M3x8 screws on the display cable holder (printed part).
⬢Carefully slide up the print display cable holder and remove it from the printer.

⬢Leave the LCD cable free. We need to release some other screws before we can remove the display.
⬢Cut the resin sensor cable closer to the connector on the tilt frame.
Before you start cutting, DOUBLE-CHECK you have selected the resin sensor cable!
⬢Pull the rest of the cable out of the bundle.
⬢Release the M4x6r screw and remove the resin sensor with the M4w serrated lock washer. Do not throw away the screw and the washer! You will need them later on.
The screw is firmly tightened. Use the shorter side of the Allen key for easier release.
No need to cut any zip ties. We will lead the new resin sensor cable separately using a different path.
The blower fan is part of an assembly (fan, metal sheet, printed part). Let's remove it as one piece and disassemble it in parts later on.
⬢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 and place it next to the printer, like in the picture. Do not pull the cable!
⬢If the assembly does not reach a sufficient distance, try moving the zip tie to the right. If it's too tight, cut the zip tie (pliers from the SL1 kit, needle-nose pliers, nail scissors). Be careful not to cut the cables!
⬢Loosen the right screw fixing the reflector inside the printer. No need to remove the screw. We will remove it together with the reflector later.
⬢Look from above through the display hole and using the long 3mm Allen key release the left screw fixing the reflector. No need to remove the screw.
⬢Hold the reflector in your hand and carefully pull it out of the printer through the display hole. The screws may be pulled out together with the reflector.
⬢Disconnect the UV LED cable from the LED array board. There is a safety latch on the connector. Lift the latch and disconnect the connector. Be careful, not to break the latch.
If the latch is hard to lift, try pressing the connector in first to release the latch.
Some connectors can be very difficult to remove. Use more force, but be careful not to hurt yourself.
Do not throw the cable away. We will need it later.
You will no longer need the UV LED board with the heatsink.
Before proceeding to the next chapter, make sure that the printer is clean from the outside as well as from the inside. This means there is no spilled resin or hardened resin, remove dust and any grease.
⬢We are done with the disassembly!
Keep the UV LED cable and all the removed fasteners from this chapter, we will use them soon while installing the new parts of the SL1S upgrade.
⬢Checked everything? Let's move to the next chapter: 3. Upgrading to SL1S SPEED
