Do not forget that without the split step the following strategy tips will not be as effective.
Regardless of the scenario you might find yourself in at the net, just remember that you must adjust your court positioning through out the duration of each point. You must adjust after every volley you have hit. Anticipating your opponent next shot based on the volley you just hit. When attacking the net coming up from the baseline, your first volley will usual be met around the service line. The type of first volley you have hit will now determine how close you should get to the net. 

You are coming in to the net either behind your serve, a return of serve or an approach shot while your opponent is at the baseline.

A) If you hit a good solid hard low deep first volley back to the baseline player or as I describe it you just stuck it, then continue inside the service line anticipating a hard paced ball back. Since you have hit the volley with pace your opponent is most likely to return the ball back with pace as well. Therefore, it is safe for you to get closer to the net. The lob is the least likely option because it is difficult to lob a low bouncing ball with pace.

B) If you have hit a high soft deep first volley back to the baseline player or as I call it you floated it, then stop just inside the service line. Since you have hit a high bouncing ball, your opponent will most likely choose to hit a lob or a high ball back. Since the lob is the most likely option, you should remain just inside the service line.

You are coming in to the net either behind your serve, a return of serve or an approach shot while your opponent is coming in to the net as well.

A) You have just hit a low volley and stuck it to either net player’s feet then continue well inside the service line anticipating a high volley. Since you have hit a low volley to your opponent’s feet, your opponent must hit up on the ball. Therefore making it safe for you to get closer to the net in a good position to put the next volley away. A lob volley is the least likely option and the lowest percentage shot selection.

B) You have hit a floating volley to either net player allowing them to make contact above net level then stop immediately and hold your ground. Since you have hit a high volley to either net player, you have no business continuing forward because your opponents are now on offense. You will not have time to retreat. The odds of winning the point are now in your opponents favor. Do the best you can because the shot before (the floating volley) has put you on the defense.

Not only will the shot you have just hit will give you a good idea of where you should position yourself but your opponent's body language prior to making contact might give you a idea of the shot about to be hit. Regardless of the type of volley you have just hit, if you see your opponent wind up about to crush a groundstroke anywhere from behind the service line to behind the baseline, then get as close to the net as you can just as contact is about to be made since the lob is not an option. Many opponents will not disguise their shot selection well, therefore keeping a eye on their backswing just prior to them making contact should give you a good idea of their intentions.
