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
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
Add R parameter to M552 command to allow HTTP port to be configured
When listing SD card files, ignore files with a leading '.' in the
filename (e.g. files that Mac computers add to store metadata)
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
Added almost instant pause functonality
Support pause and resume macros
Support nested macros
Support zpl's web interface
Merge in zpl's web interface and network changes
Add R parameter to M105 command for PanelDue
M98 can now run macros from any SD card folder
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
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.
Changed compiler optimization option to -O2 (was accidentally reset to
-Os in previous release)
Set the number of decimal places reported in the responses to various M
commands
Integrated zpl's changes to returning lists of files, returning info for
file being printed, and some network layer changes
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.
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.
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.
Rewrote the web server command parsing as a state machine. Added support
for persistent connections, used for file uploading. Changed file upload
protocol to pass status information back. Added web message type for
deleting files.
Introduced new file upload protocol that doesn't use gcodes and allows
upload errors to be reported back. Changed file system interface in
Platform to return success/fail status of Write and Close calls to
support this.
Added new request code rr_data for file uploading, and made other
changes to improve file upload speed.
Implemented S parameter to M208 command, to allow the negative limits of
axes to be set. Also reports current limits of no X/Y/Z parameter.
Reduced max reported free buffer size to 950 bytes to avoid problems
with file upload from Windows 8.1.
If a network error occurs when sending a file, we now close that file,
otherwise we would use up open file entries. Also added number of
available open file entries to M111 S2 command.
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.
Reduced block read size when retrieving file info to work around an
intermittent bug that causes the SDHC card/ FATfs stack to return data
from the wrong sector sometimes. Tidied up some other code.
Added new variable "extr" in Json response to report extruder positions
Added new fileinfo request type, returns file size, object height, and
total filament needed (if available)
Fixed bug in returning last command response in Json response
Disable interrupts when adding/removing network request structs from
linked lists, in case lwip does callbacks from ISR contexts
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
Firmware now recovers from USB disconnection without halting. Needs
changes to Arduino core library.
Added a timeout in the Spin() functions, which causes diagnostic info to
be stored and the system to be reset if a Spin() function takes more
than 20 seconds.
Completed changes to support multiple concurrent HTTP file requests.
Added support for new poll response for future support of additional
heaters and multiple extruders. Fixed a bug in reporting extruder
distance.
Removed file httpd.c and moved its functions into Network.cpp. This
gives us type-checking across more interface boundaries and eliminates a
number of global functions. Also removed unused files fs.c, fsdata.c,
httpd-original.c.
Changed webserver and network code to support multiple concurrent
connections
Removed support for differential-mode ultrasonic z-sensor
Reduced X and Y instantDv from 15 to 10 mm/sec to allow outlines of
holes to e drawn at lower speed
Changed temperature reading code to give thermistor disconnected reading
of -273C when there is a negative high ADC offset correction
