But even if I used the servo motor 1.6Nm the pitch of the lead screw is 0.2" so I could easily convert that to 5.08mm or 0.00508m for that matter. In Canada much of what we do is metric. And my program has a check box that lets a user switch along with converting all the imperial units to metric and back.
But that's beside the point I think. None of what you said explains how to calculate the MAX_ACCELERATION in the INI file given parameters like motor/leadscrew torque, leadscrew pitch, max speed and table weight (mass). Any ideas?
