Schools out for summer! well works out for winter! Time to relax and enjoy the run up to Christmas; or plenty of time to hit my target of being able to design and cut a Christmas tree decoration in time for Christmas.
To configure the machine I need to know how to work out my steps per millimetre so I can cut accurately. For this I need the lead-screws revolutions per millimetre which, this is a problem as I don’t know the lead-screw pitch! This thing had come from China with no documentation. But there is an easy way of calculating the pitch.
