Error name: Check XL-CAN Connection
Error code: #41143 (XL+) #17143 (XL)
Check the underside of the heatbed assembly for any physical damage, loose cabling, or improperly seated connectors on the XL-CAN board and the Modular Bed controller board. Always power off the printer and disconnect it from the power outlet before inspecting or handling electronics.

If all cables are securely plugged in, undamaged, and the error persists after powering the printer back on, there may be a hardware failure on either the XL-CAN board or the Modular Bed Controller board. Contact our customer support, mentioning the error code #41143, the exact message shown on your printer screen, and pictures of the board connectors.
