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.)
* Fix G26's circle drawing...
This mostly catches the bugfix-v1.1.x branch up to bugfix-v2.0.0
I'll have to do something similar to get bugfix-v2.0.0 caught up to
bugfix-v1.1.x
* only use planner.leveling_active if appropriate
Probing with the effector in the printing area, but an eccentric probe (e.g. allen key) outside it but still touching the bed gives meaninfull information for calibration. Since calibration is most accurate when probing as close to the towers as possible the testing was way to restrictive hence this fix.
Original Mesh Bed Leveling replacement put at top of UBL Menu Options to
help facilitate the removal of the Original Mesh Bed Leveling.
Radar display (and control) of the UBL Interactive Mesh Editing.
* 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
