The answer is 42.
Seriously though, it totally depends on the build, mechanical parts, lubrication, motor current and make, personal preference etc. A good low starting point would be 1000mm/s2 acceleration for xyz and e. Speeds in mm/s: 100, 100, 3, 20 for xyz and e respectively. Vmax xy jerk 20mm/s.
In slicer use 30mm/s printing speed, 15mm/s first layer speed.
Temperatures depend on thermistor accuracy/lookup table and type and make of filament.
Calibrate it using triffid hunters guide. Then try higher speeds and acceleration and find your own 'best' settings.
