Mark Hindess 0ce252ba7a This ifdef is for bed code so should use bed constants for testing.
Without this fix, the code wont compile with extruder but without bed
runaway protection defined.

grob6000 bf2c923db5 Make multiple PID parameters a config option
* Adds config parameter `PID_PARAMS_PER_EXTRUDER` - allows single PID
parameters to be used where this would be preferable (e.g. dual
identical extruders)
* When disabled, will use `float Kp, Ki, Kd, Kc;` as before.
Preprocessor macros used to switch between.
* ultralcd.cpp defines extra menus for extra parameters only where
required
* M301 reports `e:xx` only if independent pid parameters enabled
* EEPROM structure still leaves space for 3 extruders worth, when undef
will save single parameter to all extruder positions, but only read the
first
* Switching off saves approx 330 B with no LCD enabled, 2634B with LCD
(RRD) enabled: this is significant.
* LCD modifications should be tested.

grob6000 37c7e8300f Independent PID parameters for each extruder
* Variables Kp, Ki, Kd, Kc now arrays of size EXTRUDERS
* M301 gains (optional, default=0) E parameter to define which
extruder's settings to modify. Tested, works with Repetier Host's EEPROM
config window, albeit only reads/updates settings for E0.
* All Kp, Ki, Kd, Kc parameters saved in EEPROM (version now v14), up to
3 extruders supported (same as Marlin in general)

Dino Del Favero 038fccd7a1 I have added some code in the "temperature.cpp" for have the possibility of control the time of the states with the heater drived by relays, with this feature now it is possible use PID function in conjunction with relay to control the temperature. I have made some tests and the temperature stay always in the range of +-1°C from the setted temp.
There is the possibility of turn on this features adding "#define SLOW_PWM_HEATERS" in Configuration.h

Erik van der Zalm 058e446531 Merge pull request #1037 from filipmu/Filament-Sensor
Support for a filament diameter sensor
2014-10-11 22:56:01 +02:00
Filip Mulier 62db9848d3 Improvements and bug fixes in sensor delay buffer for filament sensor code
Improvement to avoid reinitializing delay buffer with every print. Fixed
issues in buffer indexing and memory out of bounds due to floating point
imprecision.  Simplified the code by avoiding conversion to standard
diameter and 1cu mm extrusion, which caused complications in determining
mm extruded.

Filip Mulier 85649a4549 Real-time filament diameter measurement and control
This feature allows the printer to read the filament diameter
automatically and adjust the printer in real time.  Added code to read
an analog voltage that represents a filament diameter measurement.  This
measurement is delayed in a ring buffer to compensate for sensors that
are a distance away from the extruder.  The measurement is used to
adjust the volumetric_multiplier for the extruder.  Some additional g
codes (M404, M405, M406, M407) are used to set parameters and turn
on/off the control. g code M221 is updated.  Pins for RAMPS1.4, RAMBO,
and Printrboard are identified for analog input.  The configuration file
is updated with relevant user parameters.

alexborro 43c298a7a9 Add "Thermal Runaway Protection" feature
This is a feature to protect your printer from burn up in flames if it
has a thermistor coming off place (this happened to a friend of mine
recently and motivated me writing this feature).

The issue: If a thermistor come off, it will read a lower temperature
than actual. The system will turn the heater on forever, burning up the
filament and anything
else around.

After the temperature reaches the target for the first time, this
feature will start measuring for how long the current temperature stays
below the target minus _HYSTERESIS (set_temperature -
THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).

If it stays longer than _PERIOD, it means the thermistor temperature
cannot catch up with the target, so something *may be* wrong. Then, to
be on the safe side, the system will he halt.

Bear in mind the count down will just start AFTER the first time the
thermistor temperature is over the target, so you will have no problem
if your extruder heater takes 2 minutes to hit the target on heating.

Users can be confused as to which values to enter after a PID tune. Updating the message to help clarity it.

Alex Borro 5c44f6c434 Bed Heater monitoring in Controller Fan
In some cases the Bed Heater FET heats up more then stepper drivers, so
this change add the bed monitoring to the controller fan. As soon as the
bed heater is turned on, the controller fan will run as well.

Alex Borro 35905ea4f9 Allow heaters to stay full On when PWM=127
In previous version, even with PWM = 127, the system turns the FET off
and then on in the next cycle. This bevavior may increase the FET heat
dissipation.
It was fixed keeping the FET always On when PWM=127.

Erik van der Zalm 69af392554 Added HEATERS_PARALLEL (Request from reifsnyderb)
This allows a hot end with two heaters and a FET for each heater. This is useful if the FET is not capable of heating two heaters.

bkubicek d147a057ac Add the socalled "Babystepping" feature.
It is a realtime control over the head position via the LCD menu system that works _while_ printing.
Using it, one can e.g. tune the z-position in realtime, while printing the first layer.
Also, lost steps can be manually added/removed, but thats not the prime feature.
Stuff is placed into the Tune->Babystep *

It is not possible to have realtime control via gcode sending due to the buffering, so I did not include a gcode yet. However, it could be added, but it movements will not be realtime then.

Historically, a very similar thing was implemented for the "Kaamermaker" project, while Joris was babysitting his offspring, hence the name.

say goodby to fuddling around with the z-axis.
