When unpowered stepper motors still can be quite hard to turn. Why is this? Is there some way to prevent it? Can you buy steppers which are easy to turn?
I ask because I would like to be able to use my little BCA mill, which is CNC-converted, as a manual mill as well as a CNC mill.
(I can turn the knobs, but it's a question of feel, which I haven't got right)
Thanks for any replies,
