Part of Grbl v0.9
version 0.1
2009-01-25 00:48:56 +01:00
Lot of refactoring for the future. CoreXY support. - Rudimentary CoreXY kinematics support. Didn’t test, but homing and feed holds should work. See config.h. Please report successes and issues as we find bugs. - G40 (disable cutter comp) is now “supported”. Meaning that Grbl will no longer issue an error when typically sent in g-code program header. - Refactored coolant and spindle state setting into separate functions for future features. - Configuration option for fixing homing behavior when there are two limit switches on the same axis sharing an input pin. - Created a new “grbl.h” that will eventually be used as the main include file for Grbl. Also will help simply uploading through the Arduino IDE - Separated out the alarms execution flags from the realtime (used be called runtime) execution flag variable. Now reports exactly what caused the alarm. Expandable for new alarms later on. - Refactored the homing cycle to support CoreXY. - Applied @EliteEng updates to Mega2560 support. Some pins were reconfigured. - Created a central step to position and vice versa function. Needed for non-traditional cartesian machines. Should make it easier later. - Removed the new CPU map for the Uno. No longer going to used. There will be only one configuration to keep things uniform.

#ifndef spindle_control_h
#define spindle_control_h
Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

Cleaned up variable spindle output (PWM). Code and config comments. - Variable spindle speed output as a configuration option. Thanks @EliteEng! When enabled, the Z-limit (D11) and spindle enable(D12) pins switch to allow access to the hardware PWM output on pin D11. Otherwise, everything should work as it does. - Removed option for inverting the spindle and coolant enable pins. This is a safety hazard, especially for the spindle. When Grbl initializes, all pins are momentarily low until it finishes booting. If an invert is enabled, this means the spindles can be energized briefly during this time. If users need signal inversion, it’s recommended to just wire in an inversion circuit instead. - Cleared out references to spindle variable output in terms of step signal. This isn’t complete and requires more deliberation before installing. - Cleared up and cleaned up some code and config comments.
