Thank you for that, im not sure why i couldnt get the link to work, and yes that is a very interesting page. I will still however do what i said, as i will probably do a complete strip down measure and refurb on the unit including new steppers and the such.
but again thanks, its always easier to do a project when you know there is a font of knowlege such as the people on this forum to help out when you get stuck.
