AP Board refers to the Application board, it is a circuit board that controls the interaction of information within the unit. It provides a self-contained operating environment that delivers all system capabilities needed to support the printer's applications, including memory management, system firmware, graphics processing and multimedia decoding.
The AP board has a built-in product SN, the mixed-use of X1C and X1 AP boards may cause some software prompts, but it does not affect the function.
Before installing the board, please take a picture of the back side of the AP board. The metallic back cover contains a sticker with a QR code which needs to be shared with the Customer Support team.
A secondary picture of the QR code sticker located on the top right side of the printer, inside the printer frame is also necessary for the process of SN replacement
Picture of the AP board. The QR code required is located on the backside.
Connectors on the AP board
|NO.||Connect object||NO.||Connect object||NO.||Connect object|
|1||The chamber camera||4||Botton PCBA||7||USB-C cable to Toolhead|
|2||The chamber LED||5||MC board (Power)|
|3||WIFI antenna||6||MC board(Comunication)|
The AP board might need replacement in cases of abnormal voltages, components abnormally hot, burnt out, unrecoverable system failure, or firmware upgrade failure. Some of these can be detected through the log file which is sent to customer support.
Prior to commencing with the process in this guide, please make sure the machine is switched off
Power off the printer, unplug the power cord, and remove the top glass cover plate.
Open the AP board cover as shown in the pictures below which is located at the upper left part of the machine.
Undo the single screw located on the cable retainer, and disconnect the USB-C cable and the two other cables next to it which are all connected to the AP board.
Use the hair dryer to soften up the silicon glue securing the connectors, then disconnect the camera cable, the chamber LED cable, and the button board cable. Finally remove the WIFI antenna cable.
Undo the 4 screws holding the AP board in place and release the board carefully as there is still a ribbon cable attached to the end of it.
Heat up the UV glue holding the ribbon cable in place with a hair dryer. Unlock the connector holding the ribbon cable secured by very gently lifting up the little black flat marked in the below image with a red square. Once done, clean up the UV glue if any of it remains on the pins of the FPC ribbon cable.
Prepare the replacement AP board, and slide the FPC ribbon cable in the connector on AP board. Secure the ribbon cable by pressing on the little black plastic flap on the connector.
Apply some UV glue on the connector. expose the glue to UV light to harden. Alternatively, apply silicon glue instead, however, let the silicon glue stand for 60 minutes after applying before proceeding.
Once the glue has solidified, align the holes of the AP board to the frame and secure it in place using 4 screws.
Start by connecting the cables to the left of the AP board (same side as the ribbon cable), apply some silicon glue to the WIFI cable, the LED cable, the camera cable, and the button board cable, let them stand for at lease 30 mintues.
Connect the 2 standard cables first, followed by the USB-C cable to the AP board, and then secure the cable retainer with a screw.
Press fit the AP cover back in place securely and finally place the glass top cover back on.
1. When the AP board is replaced, the step of binding the machine should be skipped when it is turned on for the first time;
2. After confirming that the replacement is completed, the printer SN needs to be replaced. So please contact the service team and provide both the new SN and the old SN to complete the SN replacement. (Begins with 00M or 00W)
Connect the power cord and turn on the power. Run a Device self-test operation as shown below and if no errors occur, the replacement was successful.
Should you come across any issues, first retrace your steps and check all connections to try again. If problems persist, contact the service team for further assistance.
