Move la10c_reset into finishAndDisableStepper, which is called in both
via lcd_print_stop() and indirectly via M84, saving some space.
M84 is checked-for to determine a complete file, so it's a superior
candidate to G80 (which some people avoid due to MBL issues).
Allow the LA 1.5 MAX value to be configured in Configuration_adv.h.
Define a customizable LA10<>15 detection threshold in function of the
above limit.
Clamp the result of of the LA10->15 return value to always
respect the new LA_K_MAX.
* MK3S IR sensor detection and safe operational range fix
* debug, change of fsensor_IR_check behavior
* more doc + disable debug print voltage
* fix displaying MSG_04_OR_NEWER and MSG_03.... kudos to @ovariludovit
* better handling of fsensor not responding scenario
* Fix missing (hex) in D5 code
* Make ALL D-codes available for DEBUG mode
until now D3 and D5 needed to be defined separately
* Forgot to modify Marlin_main
Just after setting up the w2m matrix, call "clamp_to_software_endstops"
on the current_position (initially [0,0,0]) to move it to the effective
minimal position, which is usually [0,0,non-zero] due to MIN_Z and the
negative probe offset.
This is required to calculate correctly the first relative move:
planning X+10 would unexpectedly calculate a Z shift otherwise.
- Hide all prototypes related to PAT9125 to force all callers
to check for the proper sensor, since the handling differences
are substantial
- Remove unneeded lenght accounting from the stepper isr as as
consequence.
- Keep detailed soft failure counts for the MK3 on the "last print
failures" status screen, but fix build on variants without a PAT9125
by fixing the lcd stats function.
The filament sensor "chunk lenght" needs to be updated every time the
E axis resolution is changed in order to trigger at the same distance.
Introduce a new function fsensor_set_axis_steps_per_unit() and use
it consistent during init, in M92 and M350.
When upgrading K values of a LA1.0 print, also adjust E-jerk settings
(<2) if permissible according to current accell limits. The same is also
true when jerk is set mid-print via 'M205 E'.
Existing values are always restored when switching to another
compatibility mode.
TODO: Since this is stateful, we will need to save the current print
mode / acceleration and jerk in the eeprom for this to survive a power
panic (see prusa3d#2456).
M24 was always cleaning the last print failstats. But because M24 is
used to restore a print after power failure (by setting the seek
offset), it would also reset the stats incorrectly after resuming.
Check for the file index position and reset the stats only when a print
is started from the beginning of the file.
Apply the same logic to M32 and similarly handle the LA10->15 conversion
(do not re-apply the adjustment for a resumed print).
There is a chance that current_block can be NULL despite
the queue being non-empty. This can happen early after a block has been
queued, but before the isr has picked it up for processing, and/or when
the current block is at the last step and is being discarded.
Check for current_block directly to avoid this race.
Both during early init and in uvlo_tiny, display "POWER PANIC DETECTED"
if enough charge is left.
This is not worth doing in regular uvlo_, as we want to give full
priority to the X motor
If power has been lost during startup already a falling edge would be
skipped, causing the print to continue and lose its state without
being able to save again.
Check for a low line after arming the interrupt and simply wait
for reset.
Do not allow uvlo_tiny() to trigger before the previous print has
already been recovered.
A quick repeated power failure could cause uvlo_tiny to overwrite
the Z position before it has been correctly recovered.
enable/disable_z behave differently when PSU_Delta is defined.
During powerpanic and kill however we do *really* need to save energy
and poweroff the motors.
Rename enable/disable_z as poweron/poweroff_z and define some aliases so
that we can use the low-level function where needed.
Use 2 bytes to store extruder temperature during UVLO.
Re-use the storage of EEPROM_UVLO_TINY_Z_MICROSTEPS which has been freed
by previous changes.
Fixes#2303
- In both uvlo_ and uvlo_tiny, calculate Z usteps properly and adjust
the Z position to a true fullstep before disabling the motor. This
avoids shifs during recovery.
- In uvlo_tiny, instead of moving up indefinitely, adjust Z just
once using the smallest move possible (new def UVLO_TINY_Z_AXIS_SHIFT)
- Perform all the uvlo/recovery processing in physical coordinates
and MBL off: there should be no automatic Z movement!
- Disable heaters in both handlers to conserve more power.
- Add timing information to uvlo_tiny too.
- During recovery, to switch between physical and logical positioning
introduce a new "PRUSA MBL" gcode as most of the procedure is
enqueued, and no existing gcode was available.
There is frequently plenty of power left during a PP. Take advantage of
it by moving the extruder to either side of the axis to detach
completely the nozzle from the print.
Re-enable Z during this move to avoid losing the current step.
When the printer is connected to a USB host during a PP (and the host
does not lose power), the rambo can linger for longer, sometimes for
long enough to recover the print state. Drain some more power.
If the motors are off-phase, this is more likely to "bump" them to an
incorrect/reverse full-step, doing worse.
We need to ensure the motors are already positioned on a fullstep
during power panic instead.
Remove the PSU_DELTA exception: Z _always_ needs to be powered here.
Also clear the UVLO flag when using lcd_print_stop. This prevents an
aborted print which has been cancelled while unparking (just prior to
recover) to come back again at the next startup.
- Initially restore the last E position from the eeprom in any case, not
just when using absolute mode (although unnecessary: since it will be
reset later), fixing a possible unitialized position and crash during
recovery (thanks to @leptun)
- Remove useless extra calls to put the extruder in relative mode:
the extruder already starts in relative mode and is later switched to
absolute.
- Replace incorrect calls to STRINGIFY with sprintf_P
- Retract after pressure has been restored in uvlo_tiny, to be
consistent with a regular uvlo (remove the bogus double unretract
as a result).
- Set the real E position prior to the panic *after* the retraction,
using the now-fixed G92.
Do not process serial commands when re-enabling the global isr.
While printing via USB and a power panic is triggered, *any* extra
command should be ignored.
Abuse the "saved_printing" variable to inhibit serial processing.
To maintain an accurate step count (which is required for correct
position recovery), any call to plan_set_position&co needs to be done
synchronously and from a halted state.
However, G92 E* is currently special-cased to skip the sync (likely to
avoid the associated performance cost), causing an incorrect E step
count and position to be set. This breaks absolute position recovery,
miscalculation of the LA factor and possibly other weird issues.
We rewrite the handling of G92 to always sync but still special-case the
frequent "G92 E0" for performance by using a free bit in the block flags.
To avoid a sync, we relay the request for reset first to the planner
which clears its internal state and then relays the request to the final
stepper isr.
According to the reprap wiki, M46 has been assigned to display its assigned IP address, but has been disabled.
Now that Toshiba FlashAir IP address processing is working, I activate the M46 code so that I can read the IP address information via serial.
