New features:
- New M569 T parameter options to specify step pulse width, step pulse
interval, direction setup and direction hold times
- M665 now sets the M208 limits (except Z min) to match the machine
limits, so that Duet Web Control reports the correct values

synchronised to queued moves, like M117 messages
Other changes:
- Duet Web Control and PanelDue now report the coordinates relative to
the origin of the current workplace
- Rewrote dhcp_rec function on Duet06/085 to avoid goto statements
(possible fix for startup problem when using DHCP)

programmed to auto negotiate
- Added M564 H0 command to allow axis movement before homing on
Cartesian/CoreXY printers

- Possible fix to Duet 06/085 failure to start when using DHCP
|
|
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
|
|
The filament usage comments generated by Ideamaker are now recognised
A separate Z probe type (P9 in M558) is now used for BLTouch and
compatible Z probes. When this is selected, the deployprobe.g macro is
run just before each probing move, and retractprobe.g is run every time
the probe triggers, or at the end of the probing move if it doesn't
trigger
All heaters are turned off during probing moves if parameter B1 is
specified in the M558 command
The M671 command can be used with just one pair of X and Y coordinates,
which disables the manual bed calibration assistant
Continuous rotation proximal and distal joints are now supported on
SCARA printers, and continuous rotation turntables are assumed on Polar
printers
When beginning a print from SD card, macro /sys/start.g is run if it is
present
Sending M0 or M1 from a source other than the SD card no longer stops an
SD card print that is not paused
When a serial input channel detects a framing or overrun error other
than in a GCode end-of-line comment, the line of GCode in which it
occurs is discarded
When the M207 Z hop setting was changed during a print while a travel
move is in progress, at the end of the travel move the head was lowered
by the new value for Z hop instead of the original value
Endstop pins 5-9 (E2-E6) on the expansion connector are now working
If neither of the /www/reprap.htm and /www/html404.htm files was present
when the web server as asked to fetch a file, it returned a 404 error,
however there was no associated plain text response so most browsers
displayed a blank screen (fixed in Duet WiFi/Ethernet build only)
If a G0 or G1 command resulted in no movement (e.g. because it was a
duplicate of a previous line) then correct synchronisation between
subsequent movement and non-movement commands was lost

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

|
|
Merged in changes from dev branch
|
|

|
|
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.

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

didn't work
When a print was resumed after power failure, the amount of extrusion
during the initial partial move was incorrect
|
|
When a T command is sent and the current tool does not change, the
firmware now makes sure that the tool heaters are turned on, in case
they had been turned off explicitly e.g. due to upgrading WiFi
firmware
SCARA printer homing didn't take account of the crosstalk
parameters
M589 with an S parameter now flags an error if there is no I
(IP address) parameter

When logging is enabled, log entries are now written for when the
date/time/date is set
When logging is enabled, "Maximum open file count exceeded" messages are
logged
Loss of power is now handled much faster. The print is paused in the
middle of a move if necessary. The M991 parameters are changed to
facilitate this.
When resuming a print after loss of power, the head is now moved,
sideways and finally down when restoring position
Following a power failure, M916 can now be used to resume the print
instead of using M98 Presurrect.g
The heater control now switches to fast PID parameters when the
temperature is within 3C of target, instead of within 1C
The TMC2660 Stallguard detection and Coolstep parameters may now be
configured using M915. Currently, no action os performed when a stall is
signalled.
If a heater fault occurs, the print is paused instead of cancelled
All error messages relating to incorrect use of a G- or M-code now
include the G- or M-number of the command that caused them

using parameter R-1 in the corresponding M569 command
The M585 (probe tool) command is now implemented (thanks chrrishamm)
If axis lengths are adjusted by probing, a subsequent M500 command saves
them in config-override.g
If tool offsets are adjusted by probing, a subsequent M500 command saves
them in config-override.g
The layer counting mechanism has been modified to better handle GCode
files that use a different layer height when printing support
Debug messages sent to the USB port are truncated or thrown away if a
software watchdog reset is imminent

command)
The TMC2660 drivers are configured to detect short-to-ground conditions
faster
The parameters in rr_ http commands are now all order-independent
Bug fixes
An error in computing the time taken to execute moves that were not yet
frozen caused the first movement on a SCARA printer following homing to
be jerky
An extra space in the output from the M114 command confused Printerface,
causing it to print exception messages
When tuning a heater, any previous maximum PWM that was set is now
ignored
|
|

The grid defined by M557 is now stored separately from the grid loaded
by G29 S1 so that they don't overwrite each other
The resurrect.g file is no longer created or deleted during a simulated
print
SCARA prints are simulated without segmentation so that the simulation
runs much faster. In tests, the difference in the simulation time
with/without segmentation was negligible.
The change to fast PID parameters is now made when the temperature is
within 3C of the target instead of when within 1C
M408 S1/2/3 responses now include dummy values for the bed heater if
there is no bed heater
The commands to resume printing that are written to resurrect.g now move
the head to 2mm above the printing height, then sideways, then down
Bug fixes:
If a Duet3D filament sensor was connected and congfigured but flashing
an error code instead of sending filament data, the error recovery code
running on the Duet caused short pauses in the print
On a delta printer if you created additonal axes, when you tried to home
them it ran homedelta.g instead of e.g. homeu.g
On a delta printer with additional axes, you can now do XYZ moves as
soon as the towers have been homed
Fixed a possible race condition if the time and date were set at
midnight
The 4-leadscrew auto/4-screw manual bed levelling code didn't work
properly
The P parameter was missing from G10 commands written to resurrect.g
Arm angle limits are now applied when converting Cartesian to SCARA
coordinates

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

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
Fix duplicate error messatge when opening a gcode file fails

Better detection of whether a move was intended to be a printing move or
not, to handle slicers that generate moves with tiny amounts of
extrusion better
