This is going to be a stupid question and one I could answer myself by just testing it but I will ask anyway. If the stepper is set to 1600 pulses per revolution and I send it 800 pulses I'm assuming it is going to go around half way and stop... see a stupid question the I guess figuring in the gear ratio you could get very small movement like in a 3D printer (I'm not doing a 3D printer but I thought it would be a good example.)
Thanks
