I'm thinking about putting together a keyboard/mouse shelf that can be lifted vertically using a linear actuator. I was looking at the C-beam kit (C-Beam® Double Wide Gantry Actuator Bundle), but I need higher speeds. Ideally, I would want it to travel 50-70 cm in about 1 second. Could I use a different lead screw to achieve this? How fast is it realistic to go with a lead screw setup?
