Implemented F, H and R parameters to M106 command. The second fan output
on a Duet 0.8.5 now defaults to being a thermostatic fan at power up.
Improved speed of file upload to SD card
G32 is now allowed if the printer has not been homed, if there is a
bed.g file
G30 commands are no longer allowed on a delta that has not been homed
M572 parameter P (drive number) replaced by parameter D (extruder
number)
File info requests are now processed in stages to reduce impact on
printing (thanks chrishamm)
Use latest network stack and webserver modules from chrishamm (thanks
chrishamm)
Added Roland mill support (thanks RRP/chrishamm)
Added S parameter (idle timeout) to M18 ans M84 commands (thanks
chrishamm)
Moved I/O pin assignments to separate Pins.h file to more easily support
alternative hardware (thanks dnewman)
Bug fix: filament usage and % print complete figures were incorrect when
absolute extruder coordinates were used
Bug fix: file-based print estimate was occasionally returned as 'inf'
which caused the web interface to disconnect
Bug fix: M666 now flags all towers as not homed
Bug fixes to extruder pressure compensation (M572 command).
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
Added F (probing speed) and T (travel speed) parameters to M558 command
Removed M210 command because home feed rates are defined in the homing
files
Increased UART interrupt priority to avoid dropping characters sent by
PanelDue
Bug fix: M558 P3 did not leave the Z probe control pin high
Bug fix: in version 1.09j only, the move following a G92 E0 command was
sometimes executed from an incorrect start point
Fixed bugs with reads/writes from/to the SD card that spanned one or
more whole sectors
Updated to latest Atmel HSMCI driver
