Be very careful here because while Jon's right acceleration is useful it's also the biggest cause of missed steps.!! . . . .6mtr/min and 500m/s/s on 5mm pitch screws is not unreasonable speed for first use and unless your doing lots of 3D work or lots of short moves then it will be fine for most work.

Like Jon's says it a compromise of velocity or Accel so if your happy 6mtr/min then wind the acceleration up until motors stall and then back off 10-20% and you should be fine.
