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

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)

chrishamm)
Added Roland mill support (thanks RRP/chrishamm)
Added S parameter (idle timeout) to M18 ans M84 commands (thanks
chrishamm)
Moved I/O pin assignments to separate Pins.h file to more easily support
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
Added F (probing speed) and T (travel speed) parameters to M558 command
Removed M210 command because home feed rates are defined in the homing
files
Increased UART interrupt priority to avoid dropping characters sent by
PanelDue
Bug fix: M558 P3 did not leave the Z probe control pin high
Bug fix: in version 1.09j only, the move following a G92 E0 command was
sometimes executed from an incorrect start point
Fixed bugs with reads/writes from/to the SD card that spanned one or
more whole sectors
Updated to latest Atmel HSMCI driver
Added support for Duet 0.8.5 with auto detection between 0.6 and 0.85
board types
Added P parameter to M115 command to set board type
Changed M115 output to report the board type that was configured or
auto-detected
Improved ISR and step pulse generation efficiency to allow higher
movement speeds, especially wheh using 0.9deg/step motors
Added XYZE parameters to M569 command to allow driver remapping
Added R parameter to M569 command to allow enable signal to be reversed
when using external drivers (thanks dnewman)
Removed M558 R parameter because boare type 0.7 can now be set via M115
instead
Moved Fan0 RPM sense pin to PA14 to avoid conflict with Duet 0.8.5 FAN1
pin
M408 poll command can now be handled concurrently with other commands
Fixed CoreXY homing bug
Support simultaneous XY homing on CoreXY printers
Updated sample homeall.g file for CoreXY printers to do simultaneous XY
homing
Added H (height correction) parameter to G30 command
G30 S-1 now reports trigger height without changing ZS origin
Added M665 Z parameter to better support square delta printers
Changed interrupt priorities to make step pulse timing interrupt higher
priority than Ethernet (thanks zpl)
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)
Merged in zpl's latest changes to Network and Print Monitor modules,
providing DHCP and Netbios name support
Added command M999 S4321 to unlock flash memory, reset and boot to BOSSA
port
Z dive height is now relative to Z probe trigger height and default is
reduced to 3mm
Added experimental support for acoustic probe for delta printers
Bug fix: firmware once again prevents Z homing before X and Y are homed,
if the Z probe is used for Z homing
Various code tidying
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 X and Y z-probe offsets to G31 command
Reworked G31 and G32 to do less work in the step ISR and to support Z
probe on delta printers
Z probe modulation pin is now selected using M558 R parameter instead of
probe type
Incorporated zpl's Network module updates and some of his Gcodes updated
Merged RRP's 0.96 Move code into mine
Added M105 S3, M20 S2 and M36 commands for supporting TFT control panel
Added X parameter to M305 command to allow thermistor channels to be
changed
Removed space after "B:" in M105 response to avoid confusing Pronterface
Added modified lwip files that were missed from last checkin
Fixed incorrect JSON format in response to the rr_files command when no
files were found
Enabled hardware debounce filter on cooling fan RPM pin to get a correct
and stable readout
Fixed bug that caused the cooling fan PWM frequency to be 165kHz. It is
now 25kHz.
Fan RPM is now included in the web interface status response (thanks
zpl).
Many more error messages are now reported to the web interface as well
as the USB interface.
Interrupt-driven network timer task to better cope with slow SD card
writes (thanks zpl)
Module SamNonDuePin is now used for all digital and PWM pin I/O.
Refactored printing to strings and web server json response handling in
preparation for adding support for LCD display via serial link
Added a timer to record how long block writes to SD card take
Merged in zpl's changes. The FTP server is not yet reliable, in
particular trying to delete a file via FTP after copying another may
result in the Duet rebooting due to the webserver module getting stuck
in a spin loop. Also the copied file has on one occasion been observed
to be shorter than the original.
Changed webserver to support HTTP requests that span multiple TCP
messages. Changed upload code to to block file writes direct fro the
received message. Increased maximum upload message size. Changed
fileinfo command to report layer height and what program generated the
gcode file, if available.
Incoming network requests can now span multiple TCP messages. Max upload
buffer increased to 2048. Also return layerHeight and generatedBy values
when asking for fileinfo on a gcode file. This is an interim commit that
needs cleaning up before release.
Fixed problem whereby gcode files printed from SD card that used lots of
small fast moves in sequence would print jerkily if a network cable had
not been connected since reset.
Fixed problem whereby object height and filament needed were not
retrieved from the SD card file to be printed if the filename contained
spaces.
Added support for deprecated M190 command, because slic3r appears to
generate it sometimes
Added support for M564 command to allow movement without limits, copied
from RepRapPro dev branch
Fixed bug in file handling that affected SD card pause/resume
operations. Merged changes from zombiepantslol to allow a height to be
set for a Z endstop switch. Reverted to blocking USB I/O but only for
debug and M503 output. Added return codes for file close and seek
operations. Increased the size of the tail of the file that we scan for
G1 Z commands from 32K to nearly 200K.
Changed network startup to avoid long delay if no network cable is
connected
Enable DHCP support if IP address is configured as 0.0.0.0 (not working
yet)
Move thermistor parameters to M305, added parameter to configure series
resistance
Added B and W PID parameters
