Original replacement/ spare part for Epax X1-N, and X1-K 3D Printers

The mainboard is compatible with EPAX X1-N, and X1-K 3D printers with SX04 interface to the LCD screen. And its firmware uses CTB file format to print instead of CBDDLP file format.

Because of the way the screen cable slot is located, printers with X1-N mainboard have a side window outside the metal body of the printer.  This is so that replacing the LCD screen is easier for X1-N printers.

Cannot install X1-N mainboard to X1 or vice versa.  Doing so will damage the mainboard or LCD screen.
