Changed the start- and end-angles for circles in the mesh-validation-pattern to avoid crossing lines.
At the start-/end-point of the circles there is a small dot of filament on my printer.
When drawing lines after the circles the nozzle crashes into those dots and destroys the circles.
I solved this problem by rotating the start- and end-points by 45 degrees.
PronterFace keeps sending M105 requests during long operations like G29 P1, G29 P2, G29 P4 and G26. The serial buffer fills up before the operation is complete. The problem is, a corrupted command gets executed. It is very typical for the M105 to turn into a M1 (actually... M1M105 is typical).
This causes the printer to say "Click to resume..."
This is a temporary fix until we figure out the correct way to resolve the issue.
More work needed for G26.
The changes to ultralcd.cpp for is_lcd_clicked() did not encompass the
full functionality of UBL's G29 P1, P2 and P4. It also broke G26's
ability to abort in several of its phases.
This is the first pass at fixing the problem. It has been tested for
correctness for several hours but more testing needs to be done.
There may be a few follow up patches to finish covering all the corner
cases, but right now I need to merge this before any conflicts show up.
Some of these changes will need to be moved over to the bugfix-v2.0.0
branch. That will happen a few days from now.
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.)
* Remove requirement for LCD when UBL is used.
* fix previous oversights
* further refinement - error messages for P2 & P4
* require R on G26 when not using LCD; default to all points
* 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
