* Add Max7219 LED Matrix Debug Support
The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.
The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.
* Try to keep Makefile up to date.
I think I forgot to Sync before I committed last time. Some UBL
changes did not stick.
Also, update the gMax configuaration.h file so other than unique numbers
and settings, it exactly matches the default configuration.h file.
- rename to PROBING_HEATERS_OFF
- move heater pausing functionality into thermalManager
- add variables, pause(), ispaused(), other functions
- add fan pausing functionality -> PROBING_FANS_OFF
- add probing_pause() wrapper
- move pausing into do_homing_move() and do_probe_move() to minimize quiet time and so other probe types can benefit
- example configs
The Configuration.h file entries for BL-Touch have been updated to:
```cpp
//#define BLTOUCH
//#define BLTOUCH_DELAY 375 // (ms) Enable and increase if needed
//#define BLTOUCH_HEATERS_OFF // if defined the printer's heaters are
turned off during probe event
```
These are my two 'Nice' machines. Both are good example machines. The
FolgerTech i3-2020 is probably the best value kit on the market right
now. And it has developed a 'Cult Following' of hobbiests. I'll always
have an up to date Configuration.h file set for it, so it may as well be
an example configuration.
And the gCreate gMax 1.5+ is the best printer I've ever seen that runs
Marlin. For sure, I'll always have up to the minute Configuration.h
files for this printer also. I've moved over to using the gMax as my
primary development machine for Marlin. So... Besides being a good
machine, it is a nice convienience for me to have this Configuration.h
file as an 'Example'.
