Since the global feedrate can be similarly modified for moves ahead of
time, save the original feedrate in the planner as we do for
gcode_target.
This avoids having to undo feedmultiply (and machine limits!) from
"nominal_speed" as previously done.
Thanks @leptun
Remove incorrect usage of stop_and_save_print combined with the
fsensor_recovert internal instruction which would result in a
broken sequence of events and/or broken stack.
Re-use the now safe stop/recover functions in the same spot
(fsensor_checkpoint_stream) to effectively cut a hole in the current
gcode stream to insert an M600 instruction, which removes all
recursive behavior without the need of extra state variables.
When starting to replay existing USB/SD commands from a recovery state,
an immediate relative move needs to compensate for a previously
interrupted move. This is almost the norm for the E axis.
Instead of saving the relative status of the move (which needs to
account for the world2machine conversion and is not always available on
a chunked move split by MBL) save directly the calculated target
position for the move in the original plan, which is easy to replay.
While handling moves in a recursive plan, such a filament check,
ensure restore_print_from_ram_and_continue unwinds the stack by
aborting early from any call that waits on the planner.
This currently only handles G1 moves, but hard-coded behavior that can
trigger recursive behavior (such as filament change) will probably have
to be checked too.
- Introduce raise_z_above to move Z carefully when the current position
is potentially unknown, using stallguard
- Use raise_z_above for:
* filament loading/unloading clearance
* extruder spacing when preheating (to avoid buildplate marks on PEI)
* before homing to avoid damaging the build plate and to avoid
repeated Z moves as well
Since raise_z_above is conditional, it will only raise when needed.
Calling raise_z_above when the extruder position is unknown and already
at maximum travel is safe and will prevent further vertical moves.
