Been playing a bit more with Sketchup and added the spindle (see seperate thread for details on the spindle as designed by blackburn mark http://www.mycncuk.com/forums/showth...shless-spindle) steppers, leadscrews etc...

The more I look at it the more I am going to have to re-design the gantry as at the moment it will be too heavy. Will have to apply the KISS principle I think...

Below is a quick walk round video exported from Sketchup.
