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
Improved speed of response to M220 command
Limit length of text returned in response to rr_name web command, stop
on first control character, and escape and quote or backslash characters
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.
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.
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
There were some bugs that surfaced if one tried to set variables (like accelerations) for extruders
if no tool had been selected. Those should be fixed here so
that attempting such things now sets parameters for the first extruder drive if
no tool has been selected.
Fixed problem whereby gcode files printed from SD card that used lots of
small fast moves in sequence would print jerkily if a network cable had
not been connected since reset.
Fixed problem whereby object height and filament needed were not
retrieved from the SD card file to be printed if the filename contained
spaces.
Added support for deprecated M190 command, because slic3r appears to
generate it sometimes
Added support for M564 command to allow movement without limits, copied
from RepRapPro dev branch
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.
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.
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.
/*Fixed to work with multiple concurrent extruder drives:
* Default or M160 S1 (set use only one extruder drive)
* "G1 En.n" adds the float n.n to the move buffer for the selected
head
* There is no change in behaviour for one extruder drive setups, or
multiple extruder
* setups where only one drive is used at any one time.
*
* M160 Sn (set to use "n" extruder drives) eg
* "M160 S3"
* "G1 En.n:m.m:o.o" adds the floats to the move buffer in the
following way:
* moveBuffer[AXES+selectedHead) = n.n
* moveBuffer[AXES+selectedHead+1) = m.m
* moveBuffer[AXES+selectedHead+2) = o.o
* so if selectedHead=0 move buffer ends up looking like this for a 5
extruder drive setup:
* {x.x, y.y, z.z, n.n, m.m, o.o, 0.0,0.0, f.f}
* where x,y,z are the axes and f is the feedrate.
* If selected head > 0 then there is the possibility that more drives
can be set than
* exist, in that case the last values are discarded e.g:
* "T3"
* "M160 S3"
* "G1 En.n:m.m:o.o"
* would leave the move buffer on a 4 extruder drive setup looking
like this:
* {x.x, y.y, z.z, 0.0, 0.0, 0.0, n.n,m.m, f.f}
*/
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
This will allow for multi extruder printing support in future pull
requests. It works fine for single extruder setups as well as the
selected head is always E0.
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.
