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
Changed .gitattributes file to treat .inf files as binary so that their
hash values don't change and their digital signatures remain valid
Deleted duet.inf ready for adding back as a binary file
1. Changed thermocouple/RTD support to use new (fixed) version of
SharedSpi in CoreNG
2. PrintMonitor fixes:
- Speed up getting file info, because it was slow enough to cause Ajax
timeouts on some systems
- Reduce the number and volume of messages printed when debugging was
enabled, and send them only to the USB interface, because it was
overloading the message buffer system and causing Ajax errors
- Added separate time stats for file seeks
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

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
Got rid of most of module SamNonDuePin because CoreDuet now provides the
required functionality
No need to define function watchdogSetup any more because the core no
longer calls it
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
Enhancements:
- Implemented M143 and M350
- Wait until movement finished when processing M906
- Allow for additional axes in M906 reporting code
- Added support for external drivers module
- Aux2 device support is now conditional
- Added separate error code for temperature above safety limit
Bug fixes:
- Fixed spurious error report when processing corrupt input line
- When there is a temperature error, return the correct error code
- Update the overheat ADC value when changing thermistor parameters
- Fixed occasional divide by zero problem in PrintMonitor that led to
AJAX errors
- Cold extrusion prevention only checks the active tool, to allow the
same extruder and heater to be configured in multiple tools
- If extrusion is prevented because of a temperature fault, display a
message instead of silently preventing extrusion
Added timeout to output buffers destined for USB
Fixed bugs in thermocouple code
Reallocated thermocouple pin numbers
Made Roland mill and inkjet support conditional and normally disabled
Fixed issue with thermocouple code messing up the timekeeping system,
which was suspected of causing the network to be unreliable
Added support for M577 (thanks chrishamm)
Merged in chrishamm's changes including OutputBuffer fix, changes to
Roland pin numbers, rr_configfile support in web server, and Roland and
inkjet pin numbers moved to Pins_duet.h
Merged in wrangellboy's http response changes for compatibility with
Edge browser
Other minor changes
Fixed issue with rare missing steps at the end of delta moves
Fix minor delta calibration issue
Fix issue with ADC crosstalk on Duet 0.8.5
Refactored RepRap and OutputBuffer classes in preparation for fixing the
OutputBuffer bugs
Merged in Dan's thermocouple support
Define serial port allocation in Pins_duet.h
Fixed some leaks of OutputBuffer objects under error conditions
The terminating newline character in a gcode response is now added in
HandleReply
Implemented F, H and R parameters to M106 command. The second fan output
on a Duet 0.8.5 now defaults to being a thermostatic fan at power up.
Improved speed of file upload to SD card
G32 is now allowed if the printer has not been homed, if there is a
bed.g file
G30 commands are no longer allowed on a delta that has not been homed
M572 parameter P (drive number) replaced by parameter D (extruder
number)
File info requests are now processed in stages to reduce impact on
printing (thanks chrishamm)
Use latest network stack and webserver modules from chrishamm (thanks
chrishamm)

alternative hardware (thanks dnewman)
Bug fix: filament usage and % print complete figures were incorrect when
absolute extruder coordinates were used
Bug fix: file-based print estimate was occasionally returned as 'inf'
which caused the web interface to disconnect
Bug fix: M666 now flags all towers as not homed
Bug fixes to extruder pressure compensation (M572 command).
New features
============
The PWM frequency for the heated bed and for any heater used as a
chamber heater is now 10Hz for bettercompatibility with DC-AC SSRs.
The PWM frequency for fans is now configurable using the F paramete ron
the M106 command. The default is 500Hz, which gives esonable control of
fans not designed for PWM. Increase it to 25000Hz when using 4-wire PWM
fans.
When a Duet 0.8.5 board is configured or detected, the fan control is
now automatically inverted. If you previously used M106 P0 I1 in
config.g to invert it, you will need to remove that.
M579 (scale Cartesian axes) is now implemented (thanks chrishamm).
M114, M119 and M573 commands can now be executed concurrently with other
commands.
When DDA debugging is enabled, the debug output now includes all active
extruders instead of just the first two.
M408 S0 now includes the fan speeds (for PanelDue).
M119 now reports the Z probe as well as the endstop switch states.
A tool can now be defined even if a tool with the same tool number
exists already. The existing tool will be shut down and deleted.
The bed heater can now be disabled using M140 S-1 (thanks chrishamm).
The chamber heater (if present) and the endstop switch states are now
reported to the web interface (thanks chrishamm).
Increased defauklt Z prove dive height to 5mm.
Increased default PID Ki to 0.2
Bug fixes
=========
On a CoreXY machine, XY speeds were too low by a factor of sqrt(2).
On a delta machine, after running auto calibration the Z=0 height could
be slightly inaccurate, depending on the difference between the X and Z
endstop corrections
When using a non-intelligent modulated Z probe on a Duet 0.8.5, the
modulation pin number was incorrect.
The M27 (Report SD card print status) response was inverted compared to
what it should be. When in Marlin mode it now includes the "byte n/m"
field that some versions of Pronterface expect.
Cold extrusion prevention did not work - an error message was generated,
but the extruder was driven anyway.
M999 PERASE is now more reliable (thanks chrishamm).
M23, M30 and M32 commands did not work when the filename parameter
passed included an absolute path.
//A T command inside a macro file did not execute the tool change macros
files.
A memory leak occurred when a tool was deleted.
All moves are now completed before switching to CoreXY mode.
Polling requests from PanelDue were not relied to when a macro was being
executed
M667 with no parameters returned an incorrect string
