I understand what you mean, when you say there is alot of force on the motor. I did design a method to counter act this, however compared to your design it is over complex and thus more likely to fail. I like how yours deals with all the forces on all the axis in one neat solution. My solution was also bulky and thus not very good for use on the z-axis.

Going to order the bits and have a go at building some of them.

Is this your design or a common know configuration? I tip my hat to the designers.

Well that is most items covered for my machine then. I am going to order the bearings, screws and motors, start a build thread and once it is all together I was going to buy the Driver boards etc.. at the end.

Thanks for putting me in the right direction!!!!!!
