6-AXIS-USBCNC-GRBL
This repository is based on usbcnc grbl which in turn is based on native grbl 1.1f
With 6-AXIS-USBCNC-GRBL you can use 3,4,5 or 6 axis depend of definition in config.h
Also there are some bugs (from usbcnc grbl) were fixed and some improvements were done.
Some of them:
- migrate from coIDE to Atollic truestudio
- 4,5,6th axis were added
- uint16_t probe_invert_mask
- issue#36 from usbcnc
- issue#38 from usbcnc
- issue#41 from usbcnc
- issue#46 from usbcnc
- issue#40 from usbcnc
- issue#49 from usbcnc
- NEW: STP_DRIVERS_ENABLE_DELAY
- issue#48 from usbcnc. STEP_PULSE_DELAY now works
- GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE); // to enable PA15, PB3, PB4 pins
- NEW: USE_RESET_BTN_AS_ESTOP
- improved performance and stability in stepper.c issue#48 from usbcnc
- issue#60 from usbcnc
- issue#61 from usbcnc
Before homing "error:7" appears 2 times due to startup blocks are empty. It's ok. To eliminate this: set the startup blocks or comment definition in config.h
Get started
- install Atollic truestudio
- add this priject to Atollic
- configure grbl in config.h (optional. 4axis by default)
- compille it
- use st-link v2 or China clones for downloading firmware to bluepill
- configure grbl with $..= commands (optional)
- use grbl controller with UGS, GcodeSender , OpenCNCPilot or other interfaces
- you can also use UART (TX1, RX1) instead of USB to connect grbl controller via bluetooth and use with android app "Grbl Controller". Just #undef USEUSB in main.c after #include «grbl.h» or delete "USEUSB" in project properties -> C/C++ General -> Path and Symbols -> Symbols.
