WARNING: Unlike updating the myCNC software, the firmware CANNOT be downgraded after a reflash. The myCNC team recommends reflashing the control board firmware as a last resort only, and recommends seeking an explicit confirmation from the support team that the firmware reflash is warranted in order to avoid issues.
