New features
============
The PWM frequency for the heated bed and for any heater used as a
chamber heater is now 10Hz for bettercompatibility with DC-AC SSRs.
The PWM frequency for fans is now configurable using the F paramete ron
the M106 command. The default is 500Hz, which gives esonable control of
fans not designed for PWM. Increase it to 25000Hz when using 4-wire PWM
fans.
When a Duet 0.8.5 board is configured or detected, the fan control is
now automatically inverted. If you previously used M106 P0 I1 in
config.g to invert it, you will need to remove that.
M579 (scale Cartesian axes) is now implemented (thanks chrishamm).
M114, M119 and M573 commands can now be executed concurrently with other
commands.
When DDA debugging is enabled, the debug output now includes all active
extruders instead of just the first two.
M408 S0 now includes the fan speeds (for PanelDue).
M119 now reports the Z probe as well as the endstop switch states.
A tool can now be defined even if a tool with the same tool number
exists already. The existing tool will be shut down and deleted.
The bed heater can now be disabled using M140 S-1 (thanks chrishamm).
The chamber heater (if present) and the endstop switch states are now
reported to the web interface (thanks chrishamm).
Increased defauklt Z prove dive height to 5mm.
Increased default PID Ki to 0.2
Bug fixes
=========
On a CoreXY machine, XY speeds were too low by a factor of sqrt(2).
On a delta machine, after running auto calibration the Z=0 height could
be slightly inaccurate, depending on the difference between the X and Z
endstop corrections
When using a non-intelligent modulated Z probe on a Duet 0.8.5, the
modulation pin number was incorrect.
The M27 (Report SD card print status) response was inverted compared to
what it should be. When in Marlin mode it now includes the "byte n/m"
field that some versions of Pronterface expect.
Cold extrusion prevention did not work - an error message was generated,
but the extruder was driven anyway.
M999 PERASE is now more reliable (thanks chrishamm).
M23, M30 and M32 commands did not work when the filename parameter
passed included an absolute path.
//A T command inside a macro file did not execute the tool change macros
files.
A memory leak occurred when a tool was deleted.
All moves are now completed before switching to CoreXY mode.
Polling requests from PanelDue were not relied to when a macro was being
executed
M667 with no parameters returned an incorrect string
Enabled gcc compiler warnings. Fixed over 100 warnings including at
least one actual and several potential bugs.
Simplified delta calibration code and added X and Y parameters to M665
command
Implemented chamber temperature commands (thanks chrishamm)
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
Fixed bug: when uploading to SD card via USB the file was printed
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
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.
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.
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 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
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
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.
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...
