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.
/*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}
*/
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.
