MCP4728 consistency & fix ultralcd.cpp
The MCP4728 DAC controls the stepper motor current strenth on the
PRINTRBOARD Rev F and RIGIDBOARD V2 boards.
PR #5792 on 9 FEB 2017 implemented default drive percentages but only on
the RIGIDBOARD V2.
This change moves the default settings to Configuration_adv.h.
Also, ultralcd.cpp won't compile because of a type def conflict.
Changed it to match the one in stepper_dac.cpp
===========================================================
reword stepper curent section for clarity
===========================================================
change name & improve comments
===========================================================
changed name from A4JP to SCOOVO_X9H per PR #6139
# This is the commit message #2:
fix typo
==============================================
clarified BLTouch calculation & changed comment delimitters/flags
I found it hard to pickout the various sections in this area so I
changed most comments from // style to /** ... */
Made the BLTouch calculation simpler and clarified the units of measure
for the result.

add changes to example configurations
============================================
add TinyBoy2 to this PR & add BLTouch Delay
I've just uploaded a major change to pinsDebug.
The big change was creating an array in FLASH that contained every
active pin definition. That reduced the RAM memory usage considerably
but increased the FLASH usage.
Creating the array requires going through the pin list twice. Rather
than having two copies of it in the code I moved the list out to another
file (pinsDebug_list.h) and then just did two #includes.
From the user’s view they’ll see the following changes:
1. Now reports all the names assigned to a pin
2. The port is now reported in addition to the pin number.
3. When PWM0A & PWM1C share a pin, both PWMs are reported
4. More PWM/Timer info is reported
One new item that may cause some concern is the usage of the LINE
predefined preprocessor macro. It may not be available if the Arduino
IDE goes to a different compiler.
Includes support for 1284 & 1286 families.
Memory usage changes when enabling PINS_DEBUGGING:

2) moved as much as possible into the function
This required creating two arrays of address pointers for the PWM

The offset for Z_DUAL_ENDSTOP (z_endstop_adj) is already in Marlin.
This PR just makes it a configuration item.
z_endstop_adj is initialized in two places so both had to be modified.

The fix in #6251 for bilinear Z offset was flawed and broke the Z parameter of G29 for bilinear levelling. This is reverted and a different fix is used for the double-addition of the Z-probe offset to the bilinear correction grid.
Since run_probe was altered to return the probe Z position rather than the nozzle Z position bilinear levelling has been broken because the Z-offset has been applied twice - once in the run_probe function, and then again in the G29 code for bilinear levelling.
The TB2 is a Indiegogo funded 3d printer. It uses a MKS SMELZI V1.0
main board (based on MELZI, i.e. Sanguinololu). I comes as a complete kit,
including display and panel.
Two variants exists, L10 and L16, with a height of 100 and 160 mm.
The heating function of the provided bed can enabled by soldering a
thermistor and some wires to it.

With the the current definition of echo_command I cannot compile RCBugFix (Arduino IDE 1.8.1) with the error "invalid conversion from 'const char*' to 'char*'". This change resolves that.
After wraparound, pwm_count <= pwm_mask holds, thus soft_pwm_X <= pwm_count
guarantees soft_pwm_X < pwm_mask is true, and the heater will be switched
off in the first branch.
Do not evaluate the pwm conditions a second time, this reduces the
instruction count (4 instructions per PWM) and text size (6 byte).

The compiler is not able to reuse the value of pwm_count, but reloads it
on every evaluation, if is stored in a static variable, as it cannot prove
it will be unchanged. A variable with local scope may not be modified from
the outside, so its value can be reused.
Doing so reduces text size and instruction count.

If dithering is enabled, the remainder of the soft_pwm_X duty value at
turnoff time is added to the next cycle. If e.g. the duty is set to 9 and
SCALE is set to 2, the PWM will be active for 8 counts for 3 cycles and
12 counts on each fourth cycle, i.e. the average is 9 cycles.
This compensates the resolution loss at higher scales and allows running
fans with SOFT_PWM with significantly reduced noise.

A 128 step PWM has 127 intervals (0/127 ... 127/127 duty). Currently, a
PWM setting of 1/127 is active for 2/128, i.e. double the expected time,
or, in general n+1/128 instead of n/127.
Fixes issue#6003.

Made the double touch portion a conditional compile based on the
PROBE_DOUBLE_TOUCH flag.

Bugfix
The current G38 only stopped a move if it involved the Z axis.
Moved all the G38 code to it's own section and put it where it would
always be executed no matter what axis was moving or if the endstop was
enabled.
Also added a comment to configuration_adv to alert the user the double
tap had to be turned on.
==============================================
Change G38 back to using Z_MIN_PROBE
There's no Z_MIN endstop if Z_DUAL_ENDSTOPS is enabled and you have them
set to the top of the gantry.
G38 started out as using the Z_MIN_PROBE pin. I don't remember why we
changed it to the Z_MIN endstop.
The tool_change function saves the current_position to the destination
array soon after starting. Later in the switching extruder section, the
destination array is modified when moving the Z axis up & down. A later
section of tool_change moves the head back to the “original location”
using the destination array. This later section assumes that the
destination array hasn’t been modified.
The fix is to save the destination Z position and then restore it after
the Z movements have completed.
Going back to using the current_position array for the switching
extruder Z axis moves (and leaving the destination array untouched)
doesn’t fix the problem.
This bug was introduced by the “Make tool_change kinematic compatible”
commit # 847429eff4 which was merged on 10
Oct 2016 as part of PR 4982.
This bug was discovered in Issue 5966.

Instantiation of the static singleton instance thermalManager in general
requires locking, but we know its safe to do without.
Add -fno-threadsafe-statics to avoid using locking primitives, which
result in linking errors:

In the endstop testing section, add the "reverse" logic in addition to "normal" core handling.
In CoreXY/YZ/XZ steppers rotating the same direction gives X movement. Opposing directions produces Y movement.
In CoreYX/ZY/ZX this is reversed. Same = Y, Opposite = X.
----
Fixes the issue where the Y endstop was being checked when moving in the X direction, etc.
- Add configuration support for zigzags in either the X or Y axis, for
wipe pads significantly longer in one dimension.
- Add configuration for default number of zig-zag triangles, vs. a
magic number in `Marlin_main.cpp`.
- Update description of auto nozzle wiping to match functionality
If Marlin is inside the temperature ISR, the stepper ISR is enabled. If
a stepper event is now happening Marlin will proceed with the stepper
ISR. Now, at the end of the stepper ISR, the temperatre ISR gets enabled
again. While Marlin proceed the rest of the temperature ISR, it's now
vulnerable to a second ISR call.
To guarantee that the 5mS pulse from a BLTouch is recognized you need to
have the endstops.update() routine run twice in that 5mS period.
At 200 steps per mm, my system has problems below a feedrate of 120 mm
per minute.
Two things were done to guarantee the two updates within 5mS:
1) In interrupt mode, a check was added to the temperature ISR. If the
endstop interrupt flag/counter is active then it'll kick off the endstop
update routine every 1mS until the flag/counter is zero. This
flag/counter is decremented by the temperature ISR AND by the stepper
ISR.
2) In poling mode, code was added to the stepper ISR that will make sure
the ISR runs about every 1.5mS. The "extra" ISR runs only check the
endstops. This was done by grabbing the intended ISR delay and, if it's
over 2.0mS, splitting the intended delay into multiple smaller delays.
The first delay can be up to 2.0mS, the next ones 1.5mS (as needed) and
the last no less than 0.5mS.

BLTouch error state recovery
If BLTouch already active when deploying the probe then try to reset it
& clear the probe.
If that doesn't fix it then declare an error.
Also added BLTouch init routine to startup section

Made pinsDebug_Teensyduino.h the same between this PR and PR 5668 which
is for a re-written pinsDebug.h file.

1) added copyright @ GNU license header
2) a blank line crept in.
