Here were a few changes that I had to make/add lines for the 4th hotend.
A compiling problem in the Temperature.cpp and missing lines in
configuration.h and configuration_adv.h. I added these lines in all of
the example configs too.
* 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.
The previous calc was wrong. Between N points there are only N-1 gaps,
not N.
So changing AUTO_BED_LEVELING_GRID_POINTS to
(AUTO_BED_LEVELING_GRID_POINTS-1)
The compiler does not support comparing float values: "error: floating constant in preprocessor expression"
The loss in X/Y precision shouldn't matter for Z probes, as most microswitches or inductive sensors are larger than 1mm square anyway.
- Fixed issue when BAL area probing is shorter than it should be for
grid probing
- Warning when BAL activated with Delta Kinematics
- Fix XY_TRAVEL_SPEED when homing Z axis
Current defaults are all 255. If it makes sense to reduce them, they should come down together, and
be in a PID_INTEGRAL_DRIVE_MAX <= PID_MAX <- BANG_MAX relationship.
Changes to support displaying the real-time filament width and the
volume factor on a 20x4 LCD. The data is displayed on the 4th line.
First the status message is displayed for 5 seconds, and then the
filament data is displayed. The status message can be seen by
re-selecting the info screen in the menu.
Add another comment on configuration.h for the value of thermistor.
I make a pull request on thermistortables.h with my thermistor (12),but y see there is a comment on configuration with number 12 but it's not present on thermistortables.h ?
Thx
