serialqueue: Tune MIN_REQTIME_DELTA timing
The MIN_REQTIME_DELTA parameter controls when the host will flush
incomplete message blocks to the mcu.  If the message had a target
time less than 250ms it would result in a flush even if a message
block was not completely full.

In the situation where the host generates lots of queue_step commands
to the point that it fills the mcu move_queue, then it would be
possible for individual queue_step commands to become eligible for
transmit only microseconds apart.  It could also lead to a situation
where the target time was less than 250ms in the future.  The result
could lead to many small message blocks as each became flushed
individually.

Tune the MIN_REQTIME_DELTA to 100ms to reduce the chance of this.

The Klipper firmware controls 3d-Printers. It combines the power of a general purpose computer with one or more micro-controllers. See the features document for more information on why you should use the Klipper software.

Start by installing Klipper software.

Klipper software is Free Software. See the license or read the documentation. We depend on the generous support from our sponsors.
