Microswitches is still the best bet on a lead screw. If it is a short distance and is capable of a gear reduction down to 270 degrees of rotation you can use a single turn pot. There are also 3, 5, and 10 turn pots available that you can attach to the lead screw, but accuracy may suffer due to the A/D in the robot controller. You will have to figure out the quantization of 256 counts vs. rotation or distance traveled to determine if a multiturn pot would work OK for you.
