* Route errors from the host C code to the main log file.
* Support clearing MCU shutdown events from the host without having to
restart the firmware.
* Provide startup scripts so that Klippy can startup at system bootup.
* Support ASCII based commands in addition to common gcode
commands. It would be useful to support high-level commands such as
"query_endstops", "pid_autotune", and "help" instead of having to
invent cryptic gcode commands (eg, "M119" and "M303").
* Provide a better way to handle print nozzle z offsets. The M206
command is cryptic to use and it is too easy to set the value
incorrectly or to forget to set it.
* Provide a way to temporarily disable endstop checks so that a user
can issue commands that potentially move the head past
position_min/position_max.

* Implement timeouts on homing. The host currently waits forever if
an endstop is not hit during a homing operation.

* Provide startup scripts so that Klippy can startup at system
bootup.
* Possibly rework the startup order of Klippy communication with
octoprint and the mcu. Currently Klippy only starts communication
with Octoprint after it connects with the firmware. However, this
limits the ability for Klippy to communicate connection errors to
the user. It also makes it difficult for Klippy to reconnect to the
firmware and/or restart the firmware if it needs to.

so that the mcu is never requested to step at a higher rate than it
can support.
