Hello all,

I decided to do the version2 upgrade whilst v1 was still in the drawing stage. The main change was to go profile rails on all axis. I also changed the x axis steel rectangle box for 45x90mm ali extrusion as it looks simpler and more accurate to fix the profile rails onto. Same goes for the y axis ali box section except its 45x45mm extrusion. There are two qualities to buy extrusion at, light and heavy. What do most people go with.

Anyways, here are some modified drawings. The first one shows the profile update and the x axis ball nut mount which now allows for adjustment. The middle pic shows how I intend on screwing the bk support block and z motor mount opposite each other. A screw will go from the bk side, through the z rear plate and screw into the motor mount. Hope that is strong enough. Last picture shows how the z plates will be machined to make registers for profile rails and carriages and also allow space for moving parts.
