Stm32 CNC Controller

CNC Base for Blue Pill , 3-Axis 32-bit ARM based CNC Controller. STM32F103
This is GRBL 1.1f, a firmware used to control a CNC milling machine or laser engraver/cutter, for the STM32F103 micro-controller. That MCU is used on the very cheap "Blue Pill" board.
This board works with either stepstick stepper motor drivers or with external drivers using MKS-CD adapter. An adapter could be made so that drivers that use a common 5V instead of a common GND for step/dir/enable could be used as well.
Stm32 can be use for 6-AXIS-USBCNC-GRBL. you can use 3,4(default),5 or 6 axis.
