Evnovo/ Original OEM Replacement PCB V.4 (Whole Set, 3 pieces)

If you have an earlier model than the V4 (V4 has a reset button next to the screen) then you need to install all 3 pcb boards.

On earlier V1-2-3 and some early V4 you will need to install the extruder and X axis together due to changes in the extruder board.

1* Z pcb (base pcb)

1 * X axis pcb ( left side joins Z and extruder ribbon cables)

1 * Extruder pcb ( on the extruder under the cover)
