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

Updated sample homeall.g file for CoreXY printers to do simultaneous XY
homing

port
Z dive height is now relative to Z probe trigger height and default is
reduced to 3mm

if the Z probe is used for Z homing
Various code tidying
Speed factor and extrusion factor changes now take effect 1 move earlier
Default feed rate after reset increased to 3000mm/min
M574 command now accepts E parameter to that active low Z probe switches

M408 command introduced as an alternative to M105 S2 and M105 S3
When cold extrusion is prevented, say which tool was affected in the

when it was enabled again the current remained at 30%
Bug fix: cold extrusion prevention did not work
Implemented rr_config web request for zpl's latest web interface
Implemented 7-factor auto calibration for delta printers
Fix bug with fileinfo calls corrupting memory
M563 can now be used to delete tools

immediately
Merged RRP's 1.04 changes in, except that the fan output is only turned
on/off for extruding/non-extruding moves if the ancilliary PWM is set to
a nonzero value
Merged zpl's changes for binary file uploading and PrintMonitor
Fixed bug with filament-based print time estimation
Fixed bug that caused feed rate to often not be restored after running
a macro
Print Z probe offsets at end of G32 sequence if Move debug is enabled
Fixed bug with reading file info
Don't return status as Printing if just running a macro
Restored Json buffer back to 2000 bytes so as to return more files on SD
card
Limit the amount of moves we buffer so as to react faster to speed and
extrusion rate changes
Return print time left estimates in M105 S2 status response if printing
a file

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

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.
1. Fixed variable name of extrusion factors in JSON status response
2. Fixed bug: changing heat sample interval no longer messes up I and D
pid factors.
3. Ensure that name of file being printed is null-terminated.
4. Removed redundant function SetStepHypotenuse.
Fixed combined xyz move bug (thanks zpl). Reversed default direction of
X motor. Added support for M569 command. Fixed bug in execution of M503

Fixed bug: if 5 point bed compansation was used then doing G32 more than
once would try to move the head off the edge of the bed unless the first
4 probe coordinates were reset between them.
Fixed bug: if the last command in a a macro file did not end in newline
then it might not be fully executed
Bug fix: potential array underrun in Gcodes::Pop()
Reduced Z dive height back to 5mm
M563 command extended to allow the tool number origin to be adjusted. If
there is no P parameter in the command then the S parameter specifies an
offset to be added to tool numbers in T, G10, M104 and M109 commands.
This is so that multi-media gcode files generated by slic3r can be
printed without having to edit all the tool numbers in the gcode file
first. This extension is intended to be temporary, until slicer provides
a mechanism for specifying the tool numbers. A separate offset is
maintained for each data source (USB, web or SD card) and the offset for
data from the SD card is reset to zero when a new file is started. To
use this facility to print slic3r multi-media gcode files, add M563 S1
to your start gcode.
M104 and M109 commands now accept an optional T parameter to specify the
tool number, as generated by slic3r in multi-media gcode files.
Movement code from RepRapPro's dev branch incorporated, including
5-point manual or automatic bed compensation mechanism.
Heater status (off/standby/on) is included in the status poll response
for the web interface. This will be used in a future version of the web
interface.
Incorporated code from RepRapPro dev branch to allow many more
M-commands to return values as well as set them.
Incorporated code from RepRapPro dev branch to implement the M119 and
M135 commands. There is currently a bug in the M135 (set heat sample
interval) command, which means that if you change the interval from its
default value of 0.5 seconds then you need to adjust the I parameter by
the same ratio and the D parameter by the inverse ratio.
Extrusion totals are reset to zero when starting a new print from SD
card.
M301 and M304 commands to set PID parameters now take an additional S
parameter. This allows for variations in cartridge heater power and
supply voltage to be taken into account more easily.
Temperature errors are reported to the web server as well as to USB.
The Heat section of the M122 diagnostics report now shows the
accumulated PID I-term.
G90 and G91 commands now affect only the the axes, not the extruders.
Bug fix: numerous calls to strncat were being made with a 'nchars'
parameter that was larger than space available in the destination
buffer.
Bug fix: print moves received just prior to an M109 or M190 command were
not executed until after the heater had reached temperature instead of
before.
Bug fix: using G10 to set oly the active temperature caused the standby
temperature to be set to an undefined value, and vice versa
G10 can now be used to retrieve the active and standby temperatures as
well as set them
Bug fix: I and D parameters were set to incorrect values when the M301
and M304 commands were used. They also reported the incorrect values.
New T parameter added to M301 and M304 commands, to allow the I term to
be preset to a suitable value when PID kicks in
Adjusted default PID parameters for lower overshoot and less oscillation
Bug fix: when axis or bed compensation was enabled a homing move to seek
for one endstop could be prematurely terminated by another endstop
M122 command only outputs LWIP stats if debug is enabled. Prevents a
hang if no UDB cable is connected when M122 is executed.
Bug fix: when resetting, the heaters used to power up for a short time
M0 and M1 commands now turn the heaters off instead of to standby
Web server status poll response now includes the selected tool number
Fixed M122 so that diagnostics are sent to the web interface as well as
USB
Fixed M220 command to respond to speed change requests faster
Count the number of active extruders and heaters, and only send their
values to the web interface, subject to a minimum of 2 heaters and 1
extruder
Fixed buffer overrun bug in FTP LIST command that caused a subsequent
FTP delete command to crash. Increased file list buffer to 2000 bytes.
Added binary RepRapFirmware-057k-dc42.bin.
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.
1. Reworked network layer to be more robust in the presence of network
errors (hopefully). In particular, don't release transmit buffers if
they might still be needed to retry sending data because the ACK got
lost.
2. Fixed bug whereby fileinfo command looked for the print height and
filament used if the extensio was .gcode or .gc or .gco but not if it
was .g.
3. When the M25 (pause print) command is received, pause the current
gcode so that commands such as M116 (wait for temperatures) can be
interrupted.
