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.
