AnHardt d17f7ebc8a Multiply WATCH_TEMP_PERIOD by 1000UL (PR#2535) 
instead of 1000.  Else we get errors with times over 32 seconds.

Fixes the problem of these pins being left in INPUT state, as described
in #1497

MagoKimbra eb81982fcd Fix error next command in autotune (PR#2274) 
Now send only temperature for T or B, but not send OK.
Host interprets the line to show the right temperature, but not in
response to M105 then stop and send commands until it ends the autotune.

AnHardt b1404a0743 fix thermal protection state machine target temp. V2 
If the target temperature is changed then it would always stay in the reset state.
Thanks to @tonokip.

Replaces #2119

Jonathan Bastien-Filiatrault e86f2342c0 Separate the maximum integral power for the bed from PID_INTEGRAL_DRIVE_MAX / PID_MAX. 
My PID_INTEGRAL_DRIVE_MAX was at 96, which was insufficient for my bed
to reach its intended temperature. The head requires a low maximum power since
I run on 24 volts and it has a somewhat low thermal mass.

AnHardt da246f5cb1 Activate BED_MINTEMP error. 
And call _temp_error() directly for ERR_MAXTEMP_BED to avoid the only one time use of bed_max_temp_error().

Includes #2156.
 2015-05-25 13:23:19 +02:00
AnHardt 959da98d8e Call kill() only once when triggered by a temperature error 
to avoid stack overflow when called from interrupt.

Some clean up for calls of disable_all_heaters().
'disable_all_heaters()' is called in kill() and again when 'killed' is already set inside _temp_error().

AnHardt 2990c6c45f Use new kill_() for _temp_error() 
instead of stop(). We really want to require a reset and no chance to set a new temperature.

AnHardt 70163dafb9 Use _temp_error() for all errors thrown by different mechanisms 
Now ending in an endless loop.
Tidy up the output format.
We now get:
ERRORTEXT ", system stopped! Heater_ID: " HEATERID

Where ERRORTEXT can be:
"Heating failed"
"Thermal Runaway"
"MAXTEMP triggered"
"MINTEMP triggered"
and soon
"Thermal Jump"

HEATERID can be
0, 1, 2 ,3 , "bed"

This messages are always followed by the common:
"Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)"

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.

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)

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.

Simon Oliver 93f0463b21 Allow Edit menu to call fn after edit; Fix PID Ki and Kd display in menus; Actually use changed PID and Max Accel values 
Add new 'callback' edit-menu types that call a function after the edit is done. Use this to display and edit Ki and Kd correctly (removing the scaling first and reapplying it after). Also use it to reset maximum stepwise acceleration rates, after updating mm/s^2 rates via menus. (Previously, changes did nothing to affect planner unless saved back to EEPROM, and the machine reset).

Add calls to updatePID() so that PID loop uses updated values whether set by gcode (it already did this), or by restoring defaults, or loading from EEPROM (it didn't do those last two). Similarly, update the maximum step/s^2 accel rates when the mm/s^2 values are changed - whether by menu edits, restore defaults, or EEPROM read.

Refactor the acceleration rate update logic, and the PID scaling logic, into new functions that can be called from wherever, including the callbacks.

Add menu items to allow the z jerk and e jerk to be viewed/edited in the Control->Motion menu, as per xy jerk.

whosawhatsis fd5b7e0cec Separate PID_MAX from BANG_MAX 
This allows PID_FUNCTIONAL_RANGE to use a maximum duty cycle higher
than PID_MAX. This is useful for powerful heaters to heat quickly in
bang-bang mode, but use a lower duty cycle that is easier to stabilize
in PID mode.

Robert F-C 372e12f83f Implement automatic extruder/cold-end fan control based on temperature 
This change allows fan outputs to automatically turn on/off when the
associated nozzle temperature of an extruder is above/below a threshold
temperature.
Multiple extruders can be assigned to the same pin in which case the fan
will turn on when any selected extruder is above the threshold.
It also makes the M42 command compatible with the M106/M107 command.
The majority of the logic in this change will be evaluated by the
compiler at build time (i.e, low code space requirements).
