Commit b7b13588 changed the internal flush time tracking, but
introduced the possibility of motion restart occurring too close to
the last motion end in some rare cases. This could result in
internal stepcompress errors.
Track the last step generation flush time (last_sg_flush_time) and use
when recalculating the next print_time.

Add support for maximum filament diameter to hall filament width sensor.
If the diameter of the filament diameter is larger than the limit, the
virtual runout sensor will trigger. The default value is set to maximum
flow adjustment threshold to prevent oversized filament from clogging.

Call toolhead.note_kinematic_activity() on each pin update to ensure

This fixes "Timer too close" errors on SET_PIN commands that are

Rename last_kin_move_time to need_flush_time and rename
force_flush_time to last_flush_time to improve variable name clarity.
Move low-level flushing to new _advance_flush_time() so that it is

Clarify the internal naming to make a more clear distinction between
"stalling" (input not coming fast enough) and "pausing" (the need to

The set_register() code may block, and it therefore may be possible
that the loop in _init_registers() could occur in parallel with other
updates. That could result in a "OrderedDict mutated during
iteration" error.
Avoid the error by querying the latest value during each iteration of
the loop.

It's possible to build and configure tmc5160 drivers with external
mosfets that support more than 3 amps. The actual maximum for tmc5160
drivers is dependent on how the board is wired and the mosfets used.
Increase the error check to 10 amps. This error checking is primarily
intended to catch "obvious misconfigurations" (eg, specifying
milli-amps instead of amps), and the new value of 10 amps should
suffice for this task.

This reverts commit 6749985302.
A defect was found in the above commit (the input shaper code calls
note_step_generateion_scan_time() for many steppers, so the

Klipper logs an error on a failed CANbus write. Unfortunately, if the
bus becomes permanently disabled (eg, due to a user removing power to
devices on the CANbus) then it can result in the logs filling with
error messages.
Permanently disable the low-level processing of messages if CANbus
writes continually fail for at least 10 seconds. This avoids filling
the log with redundant messages.

Previous version of the code assumed that dual carriages home away
from each other, which is not true on some machines, which have the
second dual carriage homing on the first carriage. The new code
correctly identifies the relative order of the carriages now.
This fixes discrepancies between the documentation and the actual
implementation of the carriages kinematic ranges calculation.
Notes about dual_carriage homing and proximity checks changes
Fixed clearing of homing state after homing in certain modes
In case of multi-MCU homing it is possible that the carriage position
will end up outside of the allowed motion range due to latencies in data
transmission between MCUs. Selecting certain modes after homing could
result in home state clearing instead of blocking the motion of the
active carriage. This commit fixes this undesired behavior.

The RetryAsyncCommand code needs to ensure that any response messages
are not from a previous (unrelated) query. To do that it compares the
'#sent_time' from potential responses to ensure they are not from a
previous session. However, if there are any low-level serial
retransmits then the low-level code sets the '#sent_time' to zero (to
indicate that the query send time is not strictly known). That could
result in a valid response not being accepted by RetryAsyncCommand.
If a low-level connection is experiencing a small amount of periodic
retransmits it could result in multiple high-level retry attempts
failing to the point that there is a user-facing error. This could
result in "Timeout on wait for 'tmcuart_response' response" errors.
Fix by accepting responses even if there is a low-level retransmit
once the code can confirm that there can be no previous query still in
progress.

Limit the maximum temperature in MAX31865.calc_adc() to the melting
point of platinum. Above this temperature the Callendar-Van Dusem
formula does not make sense. The default value for max_temp is
99999999.9 and at this temperature the result of this formula is
negative. This sets max_sample_value to 0 which causes the mcu
to shutdown.
Set max adc value to (1<<15)-1 . This is needed because the max value of the adc register
of the MAX31865 is 0b1111 1111 1111 1110 which represents
32767 and not 32768.
