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.
Fixed a bug when one file was called from another
M111 S2 command now displays time since last reset
M106 'I' parameter now only inverts fan PWM when >0
Non-homing moves when bed probing are now done at max speed
M999 reset command now delays 0.5 second to allow response to be sent
back to browser, otherwise it may retry the reset
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.
Changed code that looks for G1 Z commands to find object height, so that
it ignores G1 Z commands in the end-of-file comments added by slic3r
1.1.1
Increased max number of open files
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
When processing an M201 command, leave the acceleration of any axis that
is not specified as the existing value instead of setting it to a silly
value.
Corrected Platform.cpp to work with long filenames - note that this fix
requires a commented-out section of code in file ff.c in the SD_HSMCI
library to be re-instated.
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.
Changed the step interrupt service routine to use the average step size
when calculating the step interval, instead of the actual step size
which depend son whether X and Y are moving simultaneously. This should
give smoother movement, because from an inertial point of view the axes
are independent. It also fixes a bug whereby the accelerations were
incorrectly calculated, because DDA::AccelerationCalculation assumes a
uniform step size directly from start point to end point, whereas the
ISR was assuming a zigzag path. Also fixed bug with resetting the
minimum z-probe value seen when using an ultrasonic transducer in
differential mode.
1. Fixed bug whereby the first XY move after a Z move would often be at
a speed much higher than requested.
2. Added support for direct-mode ultrasonic sensor using command M558
P3. Command M558 P4 selects differential-mode ultrasonic sensor.
3. Changed temperature parameter in G31 command from T to S.
Added L and H parameters to the M301 and M304 commands to allow SAM3X
ADC offsets to be corrected for. Also attempted a fix for absolute
extruder movement. - but this will still be affected by rounding error.
Removed some old binaries.
1. Fixed bug introduced at version 57r whereby axis travel limits were
not applied properly.
2. Increased maximum travel on 2nd phase of Z-probing from 1mm to 10mm
3. Added parameters R (thermistor 25C resistance) and B (thermistor
beta) to M301 command
4. Added support for M304 command with same parameters as M301 command
5. PID and thermistor parameters are now saved to flash memory
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.
Fixed M106 command so that the cooling fan is controllably by PWM and
works the right way round (0 = off, 1 = on). Also added optional P
parameter to specify the value that corresponds to maximum PWM.
Fixed a random hang after z-homing in the previous release. Also make Z
probe temperature coefficient default to zero always, and Z probe
calibration temperature default to current bed temperature always.
1. Z-probing is now done in two stages: a fast stage at the configured
home feed rate until within 10% of the target value, then a slow stage
at 20% of that feed rate.
2. Provisional support for ultrasonic Z-probe.
3. Added calibration temperature and height temperature coefficient to Z
probe parameters.
4. Z-probe parameters and Z-probe type are now saved to flash memory so
that they survive power-off and reset cycles. Separate parameters are
retained for IR and ultrasonic probes in case both are fitted.
5. Fixed issue with doing slow Z-moves immediately after Z-homing or
probing.
Implemented M301 command to get/set PID parameters. Improved the PID
parameters and made minor changes to the PID algorithm to improve PID
performance with Ormerod hot end.
1. G92 with a Z value now sets exactly that Z value even if bed
compensation is in effect.
2. If G32 is run before the Z axis is homed, the first bed probe in the
G32 sequence homes the Z axiws.
Increase TCP window size from 1 to 2 packets and increase maximum amount
of web data sent to 1460. This decreases the page load time fro a
Windows client fro 6 seconds to less than 1 second. It also fixes a
problem whereby when using a Ubuntu client, file upload and direct print
didn't work unless the reprap.js file was edited to reduce the maximum
amount of data sent per request. Also we now initialize unused memory
with known data so that in response to the M111 S1 command we can better
estimate the amount of free memory.
Reverted STRING_LENGTH to 1029 to avoid random print hangs that occurred
using 0.57f firmware. Reduced max reported buffer size to fit within
this. Report additional memory usage detail in response to M111 S0.
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
