GRBL for Chinese CNC3040-like machines. WIP.

Based on STM32F103C8T6 "Bluepill" boards with customized grblHAL firmware

Project goals:

• Develop simple open hardware plug to replace the vanishing parallel port
  • Support configurable pin assignments
  • Support extra controls not available on CNC3040 such as mist, flood, spindle RPM reader
• Add support for more axis. (at least add A axis)
• Support other features that LinuxCNC have

Development Environment

IDE	STM32CubeIDE v1.2.0
Controller board	STM32F103C8T6 (Bluepill)
