Bug fix: M92 command would only set extruder steps/mm if either 1 or 5
extruder steps/mm was provided
Bug fix: Z-homing or bed probing when axis compensation was enabled
caused the X and Y origins to shift
We now mark drives as not homed when we disable them
File info code now supports gcode files generated by Simplify3D
Updated SD card files to latest web interface
Added more comments to config.g
Head movement commands that were in the tfree files have been moved to
the tpre files, to work better when G10 nozzle offsets are used
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.
Refactored printing to strings and web server json response handling in
preparation for adding support for LCD display via serial link
Added a timer to record how long block writes to SD card take
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
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.
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.
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.
Fixed bug whereby incoming gcodes were URI-decoded twice, which could
cause problems if a comment contain a % character
Fixed bug whereby M109 and M190 waited for all heaters to reach target
temperature instead of just the one involved
Fixed bug whereby files whose names contain an uppercase letter G could
not be uploaded or deleted
Increase buffer size for incoming gcodes
Removed parameter to set max PWM value in M106 command. Max PWM value is
now 255 as per recent RepRapPro change.
Changed the code that deals with dropping characters in unimportant
messages sent to USB such that we only drop characters at the end of a
line (adding ".\n" to whatever we send) or drop whole lines
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.
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.
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
Fixed bug introduced at version 057o-dc42 that broke the G32 bed
compensation. Added the Z heights of the bed compensation points to the
information displayed by M111 S2. Simplified the code that does
Z-probing in fast and slow stages. Added function sncatf and used it to
simplify the code in several places.
Tidied up axis homing tracking.
When checking endstops, wait for move to complete before accepting
further moves, otherwise subsequent moves use the wrong coordinates.
Temperatures and Z probes are now monitored continuously using a tick
interrupt to kick off ADC conversions. ADC is now run in 12-bit mode.
Thermistor readings are passed through averaging filters. Thermistors
are monitored for overheat conditions and bad readings in the tick ISR
and the appropriate heater is turned off (useful because the main loop
sometimes gets suspended while trying to do USB communication).
Use watchdog timer to monitor the tick interrupt - needs patch to
Arduino Due core library. Add facility to test watchdog timer (M111
S1001). Added an error status word to record that errors have occurred
(e.g. over-temperature).
M111 command changes so that S0 turns debug off, S1 turns debug on, S2
reports free memory - also now reports the type of the last restart and
the error status word. Fixed problem whereby M111 debug reports were not
sent to the web interface.
Implemented M999 command, which resets the Duet.
Removed an unused variable.
Changed some more "char*" to "const char*".
Changed extruder PID parameters and added more explanation for them.
Increase incoming web gcode buffer size to 1200 chars to allow more
gcodes to be sent in each message
Include free buffer size in poll response
Include response sequence number in poll response
Implement M30 (delete file) via USB interface
Support M503 and M111 commands via web interface
Added new fields "zprobe" and "resp" to webserver poll response
Immutable string parameters are passed as const char* not char*
Increase max number of files displayed to 42
Range-check heater parameters in incoming commands to avoid buffer
overflow if heater number is out of range
1. Z home now moves home, rather than just setting the coordinate.
2. Wait for temps implemented.
Also the JSON requests for the g code filelist has been temporarily commented
out in reprap.htm. It was causing the firmware to hang sometimes. To be investigated.
Machine now prints nicely...
