Example Configuration.h files are not updated yet. You need to cross
your settings over to the default Configuration.h file in the \Marlin
directory. (UBL_G26_MESH_VALIDATION enablement has moved to a new
location in the file.)
* Change all direct changes of ubl.state.active to
set_bed_leveling_enabled() which handles apply/unapply
leveling to maintain current_position consistency.
Fix invalidation of UBL mesh to invalid unreachable
mesh points as well (delta corners).
Fix UBL_DELTA unapply_leveling logic and when
it gets applied, including fade_height changes.
Add optional M114 D for detailed position information,
disabled from compilation by default (M114_DETAIL).
* UBL_DELTA raw and inline kinematics
* UBL planner fall through fix
* consistent variable names
* Cleanup orphaned code and whitespace changes.
Use _O2.
* compile warnings cleanup
* Remove redundant #ifdef condition
Firmware was forgetting the z_fade_height in Planner, set by M420 Z<f>,
after each reset or loading settings from EEPROM. Added the float
z_fade_height to EEPROM-Storage, now remembers the value.
The target here is to update the screens of graphical and char base
displays as fast as possible, without draining the planner buffer too much.
For that measure the time it takes to draw and transfer one
(partial) screen to the display. Build a max. value from that.
Because ther can be large differences, depending on how much the display
updates are interrupted, the max value is decreased by one ms/s. This way
it can shrink again.
On the other side we keep track on how much time it takes to empty the
planner buffer.
Now we draw the next (partial) display update only then, when we do not
drain the planner buffer to much. We draw only when the time in the
buffer is two times larger than a update takes, or the buffer is empty anyway.
When we have begun to draw a screen we do not wait until the next 100ms
time slot comes. We draw the next partial screen as fast as possible, but
give the system a chance to refill the buffers a bit.
When we see, during drawing a screen, the screen contend has changed,
we stop the current draw and begin to draw the new content from the top.
lcd_update can take so much time that the block buffer gets drained if
there are only short segments. This leads to jerky printer movements for
example in circles and a bad print quality.
This change implements a simple check: Only if the block currently
executed is long enough, run lcd_update.
This also means the printer will not show actual values on the LCD nor
will it respond to buttons pressed. A option that keeps the menu
accessible is also available.
Aditionaly, slow down if a block would be so fast that adding a new
block to the buffer would take more time. In this case, the buffer would
drain until it's empty in worst case.
planner.h:
fan speed is used to set integer variables, so no need for long.
Basicaly a byte should be enough for all the fan things, as it's 0-255?
planner.cpp:
Save some float multiplications.
We could squeeze out even more by defining feedrate_percentage,
saved_feedrate_percentage and flow_percentage as float instead of int.
Everytime they are used in the time-critical planner, they are casted to
float and multiplied by 0.01. Not done jet, as they are used in LCD menu
functions I don't know well enough.
