H-Grbl

This project is intended to run Grbl on a system based on H-bridges and Arduino Nano (and clones): Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling.

More informations and files can be found here: http://xn--zabaaganionemiejsce-8fd.pl/arduino/h-grbl/

Installation: Just extract H-Grbl library into libraries folder and use H-Grbl example file.

TODO:

  • convert digital/analogWrite to port manipulations
  • repair disable steppers function - propably will be repaired by converting to port manipulation
  • check what in homing cycle can be problematic for X-microstepping
  • Put some settings in defaul settings file.
  • $H for non-modal/modal and other situations (motion_control.c, 252 line).

DONE:

  • $H to set X=0, Y=0, Z=10 (motion_control.c, 258-260 lines)
