Bug fixes:
DWC sometimes disconnected after uploading a GCode file
Reverted the behaviour of G0 commands to the pre-2.0 behaviour when the
machine mode is FFF (i.e. the F parameter is recognised and the feed
rate is shared with the G1 feed rate)
If a G1 command with extrusion was followed by a G0 command, the
extrusion was repeated in the G0 command
When high microstepping was used, certain sequences of movement commands
could lock up the movement system

Use our own version of vsnprintf to save stack and avoid needing to stop
scheduler during calls to it
G0 now moves at maximum travel speed and ignores F parameters

Initial build using FreeRTOS
|
|
Upgrade notes:
- On Cartesian and CoreXY printers, normal G0 and G1 moves are no longer
allowed before the corresponding axes have been homed. In particular, if
your homex.g, homey.g and homeall.g files raise Z a little at the start
and lower it at the end, you will need to add the S2 parameter to those
G1 Z moves. Otherwise the G1 Z move will be refused unless Z has already
been homed and the homing macro will be terminated.
New features:
- On Cartesian and CoreXY printers, normal movement commands are no
longer permitted until the corresponding axes have been homed
- Illegal movement commands in a print file or macro file cause the file
to be terminated and heaters/spindle motors/lasers to be turned off;
except that when the printer is in FDM mode, G0 and G1 moves outside the
movement limits are just truncated as before
- The M39 command reports the SD card cluster size
- If GCode attempts to set the temperature of a non-existent bed or
chamber heater to zero (to turn it off), the error message that would
normally be generated is suppressed
- G60 command to set a restore point is implemented
- M671 command now supports the F (fudge factor) parameter
- The standstill current fraction can now be set on the Duet Maestro
build
- M118 support added (thanks chrishamm)
- When using external stepper drivers the DIR signal is no longer
changed before the step pulse has ended
- The M452, M453 and M573 commands now support the I1 parameter to
invert the laser, spindle or extrusion signal polarity
Bug fixes
- Duet Ethernet only: fixed bugs in the DHCP client code that could
cause the printer to become very slow
- G2 and G3 arc moves are terminated if the attempt to exceed the axis
limits
- When multi-touch Z probe mode is enabled, the recovery time is applied
before all probing movements, not just the first one
- Z probe mode 9 (for BLTouch) ow works in multi-touch mode
- During simulation the status is set to "Simulating" instead of
"Printing"
- M556 with a zero S parameter no longer messes up the coordinate
calculations
- When large files were uploaded or copied to the SD card and the
cluster size was small, HTTP requests could time out while DWC attempted
to get the information for those files
- The Duet3D rotating magnet filament monitor is supported again
- FTP didn't work reliable in 1.21RC2
- Endstops 5 thru 9 on a DueX2/DueX5 board can now be used for simple
filament sensors
- When resuming a paused print the first move executed was sometimes
incorrect

Merged in changes from dev branch
|

New features:
T R1 activates the tool that was active at the last pause
M915 R2 and R3 actions are now implemented
Extruder heater PWM values are now compensated for supply voltage
Duet WiFi only: M587 and M589 without parameters now report the IP
addresses etc. as well as the SSID (needs DuetWiFiServer 1.20beta9)
When sensorless homing is used on a CoreXY printer, both X and Y motors
are monitored for stalling when homing X or Y. Similarly for CoreXYU
(both X and Y or U and V are monitored).
When using a segmented kinematics such as SCARA, or when long moves are
segmented due to mesh bed compensation, segmented moves can be paused
between segments
M562 with no parameters now clears all heater faults
New debugging module 14 added to report debugging message from the WiFi
module to USB. Use M111 S1 P14 to activate it.
Under voltage and over voltage events are now logged
Overheating drivers are now logged
M81 power off commands are now logged
Bug fixes:
Workaround for SX1509B chip problem: if an analog write was performed to
a pin on an SX1509B device, subsequent digital writes and pinMode calls
didn't work
When a print was resumed after power failure, the amount of extrusion
during the initial partial move was incorrect

M109 activates the tool if no tool or a different tool was activated

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

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

9 on a Duet 0.6
M408 status requests were not handled when in simulation mode

|
|
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
|
|
Fixed print quality problems that mostly affected delta printers e.g. on
spiral vase cylinder
When reconnecting a browser, cancel any file upload from the same IP
address
M111 now prints the number of each module with debugging enabled or
disabled
In special moves on delta printers, the F parameter is now interpreted
as the speed of the tower that moves the most
M114 now reports stepper positions as well as head position
Default to output in Marlin mode
M104 command defaults to the only tool if there is only one tool and it
is not selected
Trying different code for M999PERASE command to see if we can get it to
unlock flash and reset more reliably
When step errors are logged, report them immediately if Move debugging
is enabled. Also reports the total number of step errors in M122.
Changed interrupt priority to make tick interrupt higher priority than
step interrupt, because we rely on the tick interrupt to check for over
temperature conditions and kick the watchdog
|
|
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.
