This is an alternative firmware for a CNC Offline Controller that is frequently sold with 3018-type CNC machines.
The controller has an STM32F103C8 MCU, 128x64 two-color OLED display, SD card slot and USB socket.
The firmware uses Arduino framework to make it usable for DIYers and hackers. Firmware is supposed to talk to any GRBL-enabled CNC machine, including lasers. At the moment the firmware allows jogging, spindle/laser control and (mostly) running jobs from SD card.
