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

New features:
M109 and M104 commands now set both the active and the standby
temperatures of the tool.
M109 now only selects a tool if no tool was selected
Filament errors are now logged
M587 now checks that the password is either empty or is at least 8
characters long
M122 now includes the minimum and maximum StallGuard registers for each
driver seen since the last M122 command
M307 now accepts an F parameter to allow the PWM frequency to be set.
Caution: do not use excessively high PWM frequencies, especially with
the bed heater, because you may overheat the mosfets.
The calculation of PID parameters from the heater model has been changed
to provide faster heating and less risk of undershoot
The M81 command now accepts an optional S1 parameter, which defers the
power down until al thermostatic fans have stopped
SD card detection is now working properly (Duet WiFi/Ethernet only)
A file that is open on the SD card can no longer be deleted
Bug fixes:
M109 commands could cause unwanted head movement when no tool change was
required

each time but a message box would only be displayed the first time
If a new request arrived but no responder was available, there was no
timeout waiting for a responder (thanks chrishamm)

|
|
Merged in changes from dev branch
|
|
Refactored to make network configuration less depedent on board ID
Added DuetM configuration
|
|
New features:
- Added Hangprinter kinematics. Auto calibration is not
expected to work yet.
- Added M122 P1 command for use in the Duet test
procedure
- Changed a path to a file in the linker command line to work
around an intermittent Eclipse bug
- DuetWiFi/Duet Ethernet: the
secondary hardware watchdog is now enabled and generates an interrupt,
so that if interrupts are enabled at the time then a crash dump can be
saved. If this fails then the primary watchdog will reset the processor
as before.
Bug fixes:
- Fixed issues caused by insufficient RAM (stack
running into heap) by freeing up additional RAM in the movement
structures
- Fixed occasional hang in USB ISR
- M201/203/208/566
commands now allow parameters for invisible axes to be set
- If a M584
command does not include the P parameter, the number of visible axes is
only set to the number of total axes if new axes are created in the
command
- Reverted to rounding down in step time calculations, because
the change to round to nearest may have contributed to issues seen by
some users of 1.20beta10
- Set correct priority for interrupt from the
UART used to receive debug info from the WiFi module
- When a filament
error occurred, the message displayed was one of the lines written to
resurrect.g instead of the type of filament error. Similarly if the
print was paused due to a motor stall.

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

SCARA printers can now use the manual bed levelling assistant
When using the manual bed levelling assitant, don't give an error if the
bed screw corrections were out of range, and always leave the first
screw alone
M552 now supports connection to a specified SSID
M572 now allows multiple D values
Thermocouple type letter in M305 command may now be in lower case
Bug fix: G29 bed probing on a SCARA printer gave spurious "not
reachable" warnings and skipped probe points
Protect against a dud command line containing the letter M being
interpreted as a M0 command
Fix reference to towers in the error message when trying to move a SCARA
printer before homing it
When updating firmware, warn that USB will disconnect

New and changed features:
- Experimental resume-after-power-failure support on Duet WiFi/Ethernet.
See
https://duet3d.com/wiki/Setting_up_to_resume_a_print_after_a_power_failure.
- Partly implemented bed levelling using multiple independent Z motors
(M671). See
https://duet3d.com/wiki/Bed_levelling_using_multiple_independent_Z_motors.
- If the G10 command is used to set the standby temperature of a tool
that is on standby, the live temperature is adjusted accordingly
- SCARA parameters configured using M669 now include X and Y bed origin
offsets
- Baby stepping is no longer cleared when you home the printer or probe
the bed
- The Y axis can now be mapped in a similar way to the X axis
- When the WiFi module is in access point mode, M122 displays the number
of connected clients (needs DuetWiFiServer 1.19beta9)
- The M305 command now uses the S parameter to set the heater name
instead of the H parameter
- The meaning of the first M669 crosstalk parameter for a SCARA printer
has changed. A zero value now means that the proximal motor does not
affect the proximal-to-distal arm angle.
- The CoreXY kinematics calculations have been changed to conform to the
way they are defined in other firmwares and at CoreXY.com. See the
important upgrade notes. The CoreXZ and CoreXYU kinematics have been
changed similarly.
- The maximum allowed target temperature for auto tuning now depends on
the configured maximum temperature for that heater
- The heater gain that provokes a warning when setting heater model
parameters with M307 or after auto tuning now depends on the configured
maximum temperature for that heater
Bug fixes:
- G2 and G3 arc movement commands didn't work when the X axis was mapped
- On an IDEX machine there was unwanted movement of the new tool after a
tool change occurred
- Duet WiFiServer 1.19-beta9: fixed a bug that sometimes caused WiFi
connection failures
- On the Duet WiFi, if the own access point parameters were configurds
but the list of remembered host access points was empty, the own access
point name appeared in the remembered list displayed by M587
- On a SCARA mnachine, sending G92 X0 Y0 caused the Duet to return
position data containing NaNs to Duet Web Control, which caused it to
disconnect
Upgrade notes:
- **Important!** On a CoreXY machine, you need to either swap the X and
Y motor connections, or set the Y axis factor to -1 in the M667 command.
Similarly for CoreXZ and CoreXYU machines.

- Added support for M374 (save height map) and M375 (load height map)
- Added M376 (set bed compensation taper height)
- Added T parameter to G31 command
- M500, M501 and M502 now use config_override.g instead of flash memory.
The parameters saved and restored are:
-- M307 auto tune results
-- PID parameters, if you used M301 to override the auto tune PID
settings
-- Delta printer M665 and M666 settings
-- G31 trigger height, trigger value and X and Y offsets
- The M501 auto save option has been removed
- Removed S and T parameters from M301 command. Use M307 command
instead.
- M301 with negative P parameter no longer sets bang-bang mode. Use M307
instead.
- Added P parameter to the G31 command to specify Z probe type. This
allows you to view the parameters for the Z probe(s) and to set
parameters for a particular Z probe type without selecting that type.
G31 P or G31 P0 prints the parameters of the currently-selected Z probe.
- Z probe offsets are now applied during G30 probing with specified XY
coordinates, including during delta auto calibration
- Z probe recovery time is now applied from the end of the travel move
just before probing

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
