tasks (eg, mcu/host communication, temperature reading, endstop
checking) in any real-world usage.
In general, the pins for the benchmark tests are chosen to flash LEDs
or other innocuous pins. **Always verify that it is safe to drive the
configured pins prior to running a benchmark.** It is not recommended
to drive an actual stepper during a benchmark.
## Step rate benchmark test ##
The test is performed using the console.py tool (described above). The
