Is there any reason not too? I've got a load of 24v steppers I've ripped out of dead printers. I'd like to use them in a battery powered situation, but I really don't want to have a 20AA battery pack. If I run the 24v stepper coils @ 12V, is it going to damage anything? I realize that they will likely pull double the current they were rated for @ 24v, but is that going to cause smoking motors in the short term?
