The Modular Bed board is located below the heatbed, and it is covered by bed-controller-case. Each heatbed tile is connected to the Modular Bed by a cable.
⬢The bed-controller-case has engraved numbers under the corresponding heatbed tile cable, with 8 cables per each side.
Locate the heatbed tile cable based on the number of the heatbed tile.
Each connector has a safety latch. It is necessary to press the latch before disconnecting. Otherwise, the connector may get damaged.
⬢In case of a heatbed tile cable replacement, disconnect the cable from the Modular Bed board.
⬢The heatbed tiles are numbered as shown in the picture.
⬢From the Modular Bed board side, disconnect the cable associated with the heatbed tile that will be replaced.

Each heatbed tile is held in place from the bottom by four screws. Identify the ones holding the heatbed tile that will be replaced.
⬢Using the TX 8 Allen key, loosen the four M3x10rT screws that hold the heatbed tile in place, together with their M3 washers.
Do not throw away the screws and the washers! We will use them later.
⬢Remove the heatbed tile and place it away. In the example picture, the heatbed tile 7 is removed.
