With this change a mechanical or optical switch may be used to check the
availability of the filament and when the filament runs out an M600
(filament change) command is issued. This is only done while printing
with an SD card.
This feature was requested several times (issue #679), but the requests
were not accepted since it was believed that this situation should be
handled at host side. However during an SD print the control is totally
on firmware and I think that during an SD print it should be handled by
the firmware.
The original code was posted at reprap forum
(http://forums.reprap.org/read.php?1,297350) by Lazymonk. I have only
corrected some bugs of the code and improved it by adding definitions to
the configuration.h in order to make it more standardized.
- Nonlinear auto bed leveling code (includes G29, G30, Z_RAISE_AFTER_PROBING). Cleaned it up to be a delta-specific AUTO_BED_LEVELING_GRID code path.
- Allen key z-probe deployment and retraction code. Cleaned it up and added safety checks.
- Moved sanity-checks to Marlin_main.cpp
- Applied to other configuration files
- Fixed formatting of ABL output
- Passing verbose level to probe_pt
- Miscellaneous cleanup
- Put CONFIG_STEPPERS_TOSHIBA into Configuration.h
* "G1 X1 ; test" was not executing "G1 X1" due to never leaving comment mode.
* "M117 Hello \;)" printed "Hello \" to the display due to not replacing serial_char properly.
Tested with the following commands:
* M117 Hello ; test => displays "Hello" on display, ignores "test"
* G1 X1 ; foo => moves 1mm in X, ignores "foo"
* ; test => completely ignored, not even acknowledged
* M117 Hello \;) => displays "Hello ;)" on display
* M117 Hello \\;) => displays "Hello \" on display, ignores ")"
- Adapted “Enhanced G29” code referred to in #1499 and posted at
[3dprintboard.com](http://3dprintboard.com/showthread.php?3105-Auto_Bed_
Leveling-Enhanced-G29-command)
- Compatible with current G29 while adding some new arguments
- `V` sets the verbose level for serial out
- `T` (or `V` > 2) send a Topology report to serial out
- `E` works the same way as before
- `P` works as before (source used `n` or `U`/`u`)
- `L`, `R`, `B`, `F` work as before
- Still needs sanity checking for `LRBF`
