Added support for M581 and M582 commands
M25 pause command can now be used inside a macro file to pause a file
being printed from SD card
Firmware update messages are now sent to USB and PanelDue (but the
existing PanelDue firmware doesn't display them)
Added gcode queue underrun counter, displayed in M122 Move diagnostic
info
M122 responses are now sent only to the comms channel that requested
them
Added support for additional firmware modules to be updated for Duet NG
Corrected a possible problem with multiple incompatible gcodes being
executed concurrently
Support H parameter on M0 and M1 commands
When executing M0/M1 commands and no print is paused, execute
stop.g/sleep.g if they exist
Treat M25 within the file being printed the same as M226
Added additional simulation modes to help identify bottlenecks
Don't disable all interrupts when starting a new move, to reduce
interrupt latency so that we can still receive data from PanelDue
Moved some utility maths functions to CoreNG
Enhancements
=========
Added support for RTD temperature sensors
When cancelling a print, if cancel.g exists then run it instead of
turning heaters off
Improved file upload speed over the web interface
Chamber heater is now exempted from timeout
Pressure advance now reduces maximum extruder jerk setting by a smaller
amount when the extruder steps/mm is high
The Duet no longer reports itself as an Arduino Due and has its own
Windows driver
Added experimental "maximum average printing acceleration" feature
Try to improve speed of getting file information in Print Monitor
Bug fixes
======
Simulation mode was not working properly
External driver support code sometimes failed to enable the associated
drives
Fixed potential overflow if a user attempted to use non-existent driver
9 on a Duet 0.6
M408 status requests were not handled when in simulation mode
Removed hard coded PATH in project
Changed to CoreNG
Implemented chrishamm's latest Network and Webserver changes, including
Telnet streaming
Added S parameter to M997 command for DuetNG
Increased file read block size to 2K when getting file info
Fixed incorrect parameters for un-retraction moves when z-hop,
orthogonal axis compensation and pressure advance are all enabled
Further refactoring of SD_HSMCI library in preparation for moving hsmci,
dmac and rtc modules into CoreDuet
Merged in chrishamm's changes to Network, PrintMonitor, and his support
for firmware updates from SD card
Fixed print monitor issue that threw out the layer count and time
estimates when there was an initial extruder priming move in the start
gcode
Switched to the new build system that doesn't need the Eclipse Arduino
plugin and uses the CoreDuet project instead of Arduino to provide
hardware support
Enabled gcc compiler warnings. Fixed over 100 warnings including at
least one actual and several potential bugs.
Simplified delta calibration code and added X and Y parameters to M665
command
Implemented chamber temperature commands (thanks chrishamm)
Tidied up delta auto-calibration code. We now use least squares for 3,
4, 6 or 7-factor calibration.
When doing delta calibration, if a probe offset was used to adjust the
head position when probing, use the actual head coordinates instead the
probed coordinates.
Bug fix: newline was missing at end of SD card file list sent to USB
when in Marlin emulation mode.
Bug fix: Heater average PWM report (M573) sometimes gave inaccurate
values when the S parameter was used.
Added almost instant pause functonality
Support pause and resume macros
Support nested macros
Support zpl's web interface
Merge in zpl's web interface and network changes
Add R parameter to M105 command for PanelDue
M98 can now run macros from any SD card folder
Fixed bug: if 5 point bed compansation was used then doing G32 more than
once would try to move the head off the edge of the bed unless the first
4 probe coordinates were reset between them.
Fixed bug: if the last command in a a macro file did not end in newline
then it might not be fully executed
Bug fix: potential array underrun in Gcodes::Pop()
Reduced Z dive height back to 5mm
