The A5X is a CR-10S-style clone printer manufactured by JGAurora, released around July 2018. This printer was only produced in a small quantity, and is no longer manufactured. As a result, the community around this printer is small.
This printer uses the same MKS Gen L motherboard and MKS TFT28 LCD module as used on the A5 and A3S. However, the wiring and setup is different, so the firmware is not cross compatible between these models. Note, that like the A5, both the LCD module, and the main motherboard, have their own independent firmware components.
For firmware flashing instructions, please see the firmware page for the JGAurora A5.
