It is typical of me to start a project because I think it is going to be easy and then find out its not as easy as thought.
I have build the frame for the 8x4. I have bought the servos, I have the driver controllers.I have the transformer on order, and thats where I am at.
I just cant make all the descisions. I am trying to make an economical machine but when I get prices on components It blows me away. Its not that I dont have the money set aside to do this, Its just that I dont want to buy the wrong thing and find its been a waste. It is the pulleys, drive belt, Z arangement and mounting that is worrying me.
I just cant see how I am going to join all the componets and make a working machine. My tools are limited and my work space is either on unlevel ground under the house or on a half level balcony out in the elements.
I know this is meant to be a forum for winners, but I am not feeling like this at the moment.
I think I need someone to baby me through the whole project and after that I will take all the credit.
I am considering using this ( http://www.hepco.co.uk/hep02d_v.htm ) sort of linear bearing idea since it is a quater the price of other sorts of rails. They say it in not as accurate but it seems that the shop bot uses it and gets good results.
