The Sketch file i made is in Jonathans thread post #83 http://www.mycncuk.com/forums/linear...html#post52272. so you can download it and incorporate it in your model. However i advise you to produce it, when you 100% decided on the exact motors/steppers, servo, size, etc. / and the machine drawing is finished, as maybe you will need to redesign the motor holding plate, in context of your design, or just leave that plate at last, however have in mind that if you decide to drive the gantry with 1 motor for example, this will affect the whole design, as the hole where the belt goes in should be at different place. You can start though with ordering the bearings, the rotating part +the lock nuts and pulleys, that's what i did
