[Bdi4emc-help] tuning velocity and acceleration

i was slightly confused when i initially chose the max velocity and acceleration values in my .ini file. now, i have the following two questions: 1) when testing for the fastest moves, should i use the MANUAL MODE interface with the slider set to max speed or should i use g00 command or g01 with F command and what value for F? 2) once i have set max velocity and acceleration values for X,Y and Z, how do i determine max velocity and acceleration for the [TRAJ] section? djs
