● M2.0 Allen Key
● M3.0 Allen Key
PS: When replacing components, please remove the build plate and resin vat and place them aside.
Ensure the machine is powered off and disconnected from the power source for safety.
Use the M2.0 Allen Key to unscrew the two screws securing the rear cover. Then, lift the yellow marked part at a certain angle and disconnect the fan cable from the mainboard to remove the machine's rear cover.
Refer to the diagram and disconnect the cables as marked. Remove the motor cable, exposure screen cable (use tweezers to lift the end cap at a certain angle while disconnecting), optoelectronic switch cable, and strain sensor cable from the mainboard.
Lay the machine down and use a sufficiently long M3.0 Allen Key to unscrew the six screws securing the upper base plate. Slightly pry open the edge of the upper base plate sticker and finally separate the upper base plate from the base.
Use a 2.0 Allen Key to unscrew the four screws securing the convex lens bracket to the base. Remove the convex lens bracket from the base and place it aside to avoid any damage to its appearance for later assembly.
Disconnect the UV lamp board's cable from the mainboard and remove it from the slot.
Then, use an M2.0 Allen Key to unscrew the eight screws securing the UV lamp board to the base and remove the UV lamp board.
Take out the new UV lamp board, align it with the base's holes, and insert the cable into the mainboard connector. Place the upper base plate onto the base (Please do not connect the cable at this point; this step is primarily to test if the new lamp board functions properly and to avoid direct exposure to your eyes during subsequent exposure testing).
Connect the power cord to the machine's base,
Power it on, and after any abnormal self-check prompts, click "Ignore." In the main menu, select "Tools" > "Exposure," choose any exposure pattern, click "Exposure," and observe whether the UV lamp board lights up. If not, please contact the store where you purchased the equipment promptly and provide detailed information about the replacement steps. Additionally, provide a video showing the UV lamp not lighting up, and professional technicians will assist you in resolving the issue.
Align the UV lamp board, which has been confirmed to be functioning properly, with the holes in the base. Use the M2.0 Allen Key and the eight screws removed earlier to secure the UV lamp board to the base. Place the cable connections into the cable groove.
Take the convex lens bracket and the screws set aside earlier. Align the bracket with the holes in the base and use the M2.0 Allen Key to secure it to the base.
Place the upper base plate onto the base, lay the machine down, take out the screws previously removed during disassembly, and use an M3.0 Allen Key to align them with the screw holes and tighten the screws. Smooth out the upper base plate sticker.
Reconnect the motor cable, and exposure screen cable (Ensure that the blue side and end cap are aligned during assembly, and arrange the exposure screen cable to prevent interference with UV lamp exposure, which may cause foreign objects to obstruct the screen display), optoelectronic switch cable, and strain sensor cable to their original positions. You could then plug in the power and power on the printer for self-check to see if any issues remain.
During assembly, ensure that you align the rear cover's upper part and then position the lower part. Finally, use the M2.0 Allen Key to tighten the two screws securing the printer's rear cover.
