Having the original PRINTER_ACTIVE macro copied at multiple spots doesn't make sense.
Refactoring it into a non-inline function saved ~400 bytes of code.
It should be safe in terms of performance, all occurrences are at non-time critical spots.
Remove useless repeated calls to disable heaters and turn on the fans,
since this is done at a higher level.
Avoid repeating messages on the serial. Do it just once.
Make a critical alert sound unconditionally.
Calibrate C/R values via univariate minimization using golden section.
This is done in several passes:
- Bootstrap C by setting an initial high R value
- Calibrate R at the requested working temperature
- Cooldown
- Refine C to the final value
- Estimate R losses for a subset of fan speeds
- Interpolate remaining values to speed-up the process
This results in robust values which are tailored to the current
filtering constants, and avoid having to sample for an extended
time to reach the required resolution.
The refining pass could avoid cooldown if the recording buffer was at
least twice as large, so that we could record both the heating and the
steady-state, saving _considerable_ time.
Setting pullups on the ADC should trigger the model-based check, making
this redundant and wasteful.
Keep the DEBUG_PULLUP_CRASH menu so that we can verify this behavior in
the future.
Remove most of the duplicated code inside temp_runaway_stop(),
making it identical to the other temperature handlers.
Move the lower-level functions required to stop the entirety of the
machine into UnconditionalStop(). Reuse this function inside
lcd_print_stop().
Set the LCD alert message before calling Stop(), as done in other safety
handlers, so that the error is visible while the printer is stopping.
This also avoids other temporary status messages to appear before
the real issue is shown and/or STEALING the first CRITICAL alert
level before we do.
Now that the stack_error function is truly minimal,
we can check for stack errors much more frequently.
Also move away stack_error from ultralcd to Marlin_main.
Attempt to workaround the M73 C0|D0 visual issue
This is an attempt to enable alternation of time to print finish and time
to color change even in the last minute of time to color change, i.e. be
able to print "0:00C".
The proposed solution leverages the capability of the current FW to read
float values from the C|D parameter. This could have the raw benefit of
being able still to alternate this time on the LCD as "0:00C" (or
"<1min") if the slicer sends a non-zero but <1 time right before the
color change.

- Add parameter `C` to gcode `M73`
- LCD Info screen switches to change time if last `M73` gcode contains `C` parameter
- Examples:
- `M73 P5 R120` will display on LCD ` SD 5% 02:00R ` if it is printing at 100% speed
- `M73 P5 R120 C60` will display on LCD ` SD 5% 01:00C ` if it is printing at 100% speed
Slicers can generate "Time to change/pause/user interaction" using `C<mins:0-65535>` parameter to "overwrite" the remaining print time.
To switch between time to change and remaining time just send in intervals `M73` with or without `C` parameter.
