i'm not a control engineer and have little experience in this field. i've been studying a way to move a light object in a line for a distance of 32 inches or less with accuracy of 1/4 of an inch. i've looked at acme screws and stepper motor driven slides. i just had a slide quoted to me for around $2800. well that is way above my budget and was hoping somebody could recommend a cheap alternative that isn't as precise as a slide but meets my 1/4 inch requirement. thanks in advance.
