Now +fixed. + +- When investigating the above issue, it was noticed that G38.x +wouldn’t show at all, but instead a G0 would be printed. This was +unlike the v0.9j master build. It turned out volatile variables do not +like to be defined inside a C struct. These are undefined on how to be +handled. Once pulled out, all weird issues went away. + +- Also changed two ‘sizeof()’ statements in the mc_probe() and +probe_state_monitor() functions to be more robust later on. + +- Updated the commit logs to individual files for each minor release. +Forgot to update the generating script to account for this. + + +---------------- +Date: 2015-09-30 +Author: Sonny Jeon +Subject: Minor bug fixes. + +- G38.x was not printing correctly in the $G g-code state reports. Now +fixed. + +- Potential bug regarding volatile variables inside a struct. It has +never been a problem in v0.9, but ran into this during v1.0 +development. Just to be safe, the fixes are applied here. + +- Updated pre-built firmwares with these two bug fixes. + + +---------------- +Date: 2015-09-24 +Author: Sonny Jeon +Subject: Updated G28/G30 intermediate motion behavior. + +- G28 and G30’s behavior has been updated from the old NIST g-code +standard to LinuxCNC’s. Previously when an intermediate motion was +programmed, the NIST standard would move all axes to the final G28/30 +stored coordinates. LinuxCNC states it only moves the axes specified in +the command. + + For example, suppose G28’s stored position is (x,y,z) = (1,2,3) for +simplicity, and we want to do an automated z-axis tool retraction and +then park at the x,y location. `G28 G91 Z5` will first move the Z axis +5mm(or inches) up, then move Z to position 3 in machine coordinates. +Next, the command `G28 G91 X0 Y0` would skip the intermediate move +since distance is zero, but then move only the x and y axes to machine +coordinates 1 and 2, respectively. The z-axis wouldn’t move in this +case, since it wasn’t specified. + +This change is intended to make Grbl more LinuxCNC compatible while +making commands, like the shown tool retraction, much easier to +implement. + + +---------------- +Date: 2015-09-05 +Author: Sonny Jeon +Subject: Parking motion bug fix. + +- Parking motion would intermittently complete the queued tool path +upon resuming in certain scenarios. Now fixed. + + +---------------- +Date: 2015-08-29 +Author: Sonny Jeon +Subject: Optional line number reporting bug fix. + +- Fixed a bug where it would not compile when USE_LINE_NUMBERS was +enabled. + + +---------------- +Date: 2015-08-27 +Author: Sonny Jeon +Subject: Update README + + +---------------- +Date: 2015-08-27 +Author: Sonny Jeon +Subject: v1.0 Beta Release. + +- Tons of new stuff in this release, which is fairly stable and well +tested. However, much more is coming soon! + +- Real-time parking motion with safety door. When this compile option +is enabled, an opened safety door will cause Grbl to automatically feed +hold, retract, de-energize the spindle/coolant, and parks near Z max. +After the door is closed and resume is commanded, this reverses and the +program continues as if nothing happened. This is also highly +configurable. See config.h for details. + +- New spindle max and min rpm ‘$’ settings! This has been requested +often. Grbl will output 5V when commanded to turn on the spindle at its +max rpm, and 0.02V with min rpm. The voltage and the rpm range are +linear to each other. This should help users tweak their settings to +get close to true rpm’s. + +- If the new max rpm ‘$’ setting is set = 0 or less than min rpm, the +spindle speed PWM pin will act like a regular on/off spindle enable +pin. On pin D11. + +- BEWARE: Your old EEPROM settings will be wiped! The new spindle rpm +settings require a new settings version, so Grbl will automatically +wipe and restore the EEPROM with the new defaults. + +- Control pin can now be inverted individually with a +CONTROL_INVERT_MASK in the cpu_map header file. Not typical for users +to need this, but handy to have. + +- Fixed bug when Grbl receive too many characters in a line and +overflows. Previously it would respond with an error per overflow +character and another acknowledge upon an EOL character. This broke the +streaming protocol. Now fixed to only respond with an error after an +EOL character. + +- Fixed a bug with the safety door during an ALARM mode. You now can’t +home or unlock the axes until the safety door has been closed. This is +for safety reasons (obviously.) + +- Tweaked some the Mega2560 cpu_map settings . Increased segment buffer +size and fixed the spindle PWM settings to output at a higher PWM +frequency. + +- Generalized the delay function used by G4 delay for use by parking +motion. Allows non-blocking status reports and real-time control during +re-energizing of the spindle and coolant. + +- Added spindle rpm max and min defaults to default.h files. + +- Added a new print float for rpm values. +
