You could probabally do it with a Galil DMC-1500 stand alone unit, these have the same features as a PC based control, but are self contained except for a means of inputing data if needed, with such as a Maple 2 line keypad/display.
These have all the features of gearing, electronic cam etc, so if you hand cranked a screw that had an encoder on it, you could used another axis, rotary table, for example to electronically track or gear one to the other off the handwheel, the electronic gear ratio could be set by the Maple operator input.
It sounds complicated but I have installed such units as add on rotary tables on Mills etc.
The DMC-1500 can often be picked up at a good price off ebay.
