TEST_SPEED macro not compatible with latest klipper

[Arakon]

Due to the Klipper change from ACCEL_TO_DECEL to minimum_cruise_ratio, the TEST_SPEED macro fails halfways through with error Error on 'SET_VELOCITY_LIMIT VELOCITY=600.0 ACCEL=16000.0 ACCEL_TO_DECEL=': unable to parse .

I just came here to say the same thing.

The specific piece that was deprecated: printer.configfile.settings.printer.max_accel_to_decel

It's related to this pull Klipper3d/klipper#6418

and can be read about more in the discussion here:
