That doesn't really tell me much. The angle and blade height adjustments are done with screw feed on the shafts and don't require a ton of force and by using gear drive the amount of torque required is reduced significantly. being as I have zero experience with steppers I am trying to determine what steppers I can use from salvage(I love building from things thought to be junk by most) and how to determine how many steps per rotation would be most practical. Would steppers from say printers be able to do the job? Also, the fence movement will take even less torque due to the use of machine screws syncronized with sprockets and chain, so the number of steps per rotation is that would best serve my purpose is what I need to determine.
