Add an emergency-command parser to MarlinSerial (supporting M108)
Add an emergency-command parser to MarlinSerial's RX interrupt.
The parser tries to find and execute M108,M112,M410 before the commands disappear in the RX-buffer.
To avoid false positives for M117, comments and commands followed by filenames (M23, M28, M30, M32, M33) are filtered.
This enables Marlin to receive and react on the Emergency command at all times - regardless of whether the buffers are full or not. It remains to convince hosts to send the commands. To inform the hosts about the new feature a new entry in the M115-report was made. "`EMERGENCY_CODES:M112,M108,M410;`".
The parser is fast. It only ever needs two switch decisions and one assignment of the new state for every character.
One problem remains. If the host has sent an incomplete line before sending an emergency command the emergency command could be omitted when the parser is in `state_IGNORE`.
In that case the host should send "\ncommand\n"
Also introduces M108 to break the waiting for the heaters in M109, M190 and M303.
Rename `cancel_heatup` to `wait_for_heatup` to better see the purpose.

Add an emergency-command parser to MarlinSerial (supporting M108)
Add an emergency-command parser to MarlinSerial's RX interrupt.
The parser tries to find and execute M108,M112,M410 before the commands disappear in the RX-buffer.
To avoid false positives for M117, comments and commands followed by filenames (M23, M28, M30, M32, M33) are filtered.
This enables Marlin to receive and react on the Emergency command at all times - regardless of whether the buffers are full or not. It remains to convince hosts to send the commands. To inform the hosts about the new feature a new entry in the M115-report was made. "`EMERGENCY_CODES:M112,M108,M410;`".
The parser is fast. It only ever needs two switch decisions and one assignment of the new state for every character.
One problem remains. If the host has sent an incomplete line before sending an emergency command the emergency command could be omitted when the parser is in `state_IGNORE`.
In that case the host should send "\ncommand\n"
Also introduces M108 to break the waiting for the heaters in M109, M190 and M303.
Rename `cancel_heatup` to `wait_for_heatup` to better see the purpose.

double bump probing as a feature
Why double touch probing is not a good thing.
It's widely believed we can get better __probing__ results when using a double touch when probing.
Let's compare to double touch __homing__.
Or better let's begin with single touch __homing__.
We home to find out out position, so our position is unknown.
To find the endstop we have to move into the direction of the endstop.
The maximum way we have to move is a bit longer than the axis length.
When we arrive at the endstop - when it triggers, the stepper pulses are stopped immediately.
It's a sudden stop. No smooth deacceleration is possible.
Depending on the speed and the moving mass we lose steps here.
Only if we approached slow enough (below jerk speed?) we will not lose steps.
Moving a complete axis length, that slow, takes for ever.
To speed up homing, we now make the first approach faster, get a guess about our position,
back up a bit and make a second slower approach to get a exact result without losing steps.
What we do in double touch probing is the same. But the difference here is:
a. we already know where we are
b. if the first approach is to fast we will lose steps here to.
But this time there is no second approach to set the position to 0. We are measuring only.
The lost steps are permanent until we home the next time.
So if you experienced permanently rising values in M48 you now know why. (Too fast, suddenly stopped, first approach)
What can we do to improve probing?
We can use the information about our current position.
We can make a really fast, but deaccelerated, move to a place we know it is a bit before the trigger point.
And then move the rest of the way really slow.

Add an emergency-command parser to MarlinSerial (supporting M108)
Add an emergency-command parser to MarlinSerial's RX interrupt.
The parser tries to find and execute M108,M112,M410 before the commands disappear in the RX-buffer.
To avoid false positives for M117, comments and commands followed by filenames (M23, M28, M30, M32, M33) are filtered.
This enables Marlin to receive and react on the Emergency command at all times - regardless of whether the buffers are full or not. It remains to convince hosts to send the commands. To inform the hosts about the new feature a new entry in the M115-report was made. "`EMERGENCY_CODES:M112,M108,M410;`".
The parser is fast. It only ever needs two switch decisions and one assignment of the new state for every character.
One problem remains. If the host has sent an incomplete line before sending an emergency command the emergency command could be omitted when the parser is in `state_IGNORE`.
In that case the host should send "\ncommand\n"
Also introduces M108 to break the waiting for the heaters in M109, M190 and M303.
Rename `cancel_heatup` to `wait_for_heatup` to better see the purpose.

* Note that we don ' t adjust the Z software endstops . Why not ?

Add an emergency-command parser to MarlinSerial (supporting M108)
Add an emergency-command parser to MarlinSerial's RX interrupt.
The parser tries to find and execute M108,M112,M410 before the commands disappear in the RX-buffer.
To avoid false positives for M117, comments and commands followed by filenames (M23, M28, M30, M32, M33) are filtered.
This enables Marlin to receive and react on the Emergency command at all times - regardless of whether the buffers are full or not. It remains to convince hosts to send the commands. To inform the hosts about the new feature a new entry in the M115-report was made. "`EMERGENCY_CODES:M112,M108,M410;`".
The parser is fast. It only ever needs two switch decisions and one assignment of the new state for every character.
One problem remains. If the host has sent an incomplete line before sending an emergency command the emergency command could be omitted when the parser is in `state_IGNORE`.
In that case the host should send "\ncommand\n"
Also introduces M108 to break the waiting for the heaters in M109, M190 and M303.
Rename `cancel_heatup` to `wait_for_heatup` to better see the purpose.

* r_T = [ cos ( phi ) - sin ( phi ) ;
* sin ( phi ) cos ( phi ] * r ;
*
* For arc generation , the center of the circle is the axis of rotation and the radius vector is
* defined from the circle center to the initial position . Each line segment is formed by successive
* vector rotations . This requires only two cos ( ) and sin ( ) computations to form the rotation
* matrix for the duration of the entire arc . Error may accumulate from numerical round - off , since
* all double numbers are single precision on the Arduino . ( True double precision will not have
* round off issues for CNC applications . ) Single precision error can accumulate to be greater than
* tool precision in some cases . Therefore , arc path correction is implemented .
*
* Small angle approximation may be used to reduce computation overhead further . This approximation
* holds for everything , but very small circles and large MM_PER_ARC_SEGMENT values . In other words ,
* theta_per_segment would need to be greater than 0.1 rad and N_ARC_CORRECTION would need to be large
* to cause an appreciable drift error . N_ARC_CORRECTION ~ = 25 is more than small enough to correct for
* numerical drift error . N_ARC_CORRECTION may be on the order a hundred ( s ) before error becomes an
* issue for CNC machines with the single precision Arduino calculations .
*
* This approximation also allows plan_arc to immediately insert a line segment into the planner
* without the initial overhead of computing cos ( ) or sin ( ) . By the time the arc needs to be applied
* a correction , the planner should have caught up to the lag caused by the initial plan_arc overhead .
* This is important when there are successive arc motions .
