Hi,
I have seen from numerous pictures from this wonderful website that the 'normal' technique is to have a stepper directly connected to the ball screw. I am also aware that often the ball screw would have been machined down to create a spindle. Given that Steppers will have their own spindle, what is the normal method of attachment between the ball screw spindle and the stepper motor spindle?
Also, although I am starting to appreciate that stepper size is critical and gearing does not necessarily provide increased torque, I am inclined (unless convinced otherwise) to utilise a geared attachment between stepper spindle and ball screw spindle. If I were to do that, how should I respond to issues of backlash? Would a timing pulley assembly be sufficient for example?
Any opinions will be read with immense interest.
