For the last couple of months i've been designing a Core XY 'dream machine' based roughly on the E3D tool changer. I'm now at the point of ordering alu plates to be waterjet cut. The idea is to create a super stable machine that can be easily modified in the future. to begin with it will just be running a single extruder but i think that will change in the near future.
Like the E3d machine all the xy movemnts are bolted to a single alu sheet with MGN rails, the x rail is genuine hiwin but the two y rails are knockoffs. im using 10mm gt2 belts to drive the motion, all idlers are mounted on shoulder bolts screwed directly into the alu sheet.
The Z axis is made up of components i managed to 'salvage' from work (I work as a design engineer) so there are 2 13mm THK rails mounted on a 4040 extrusion, these are being driven by a IGUS integrated leadscrew and stepper.
I would apriciate constructive feedback on the design, its taken a fair few itterations to get to this point.
If you would like the solidworks files i have uploaded them on openbuilds [openbuilds.com]
Cheers!
