Imprimante 3D D-Bot Core-XY

Thanks for making this - it was an awesome project.

Slight modifications: Added additional piece of rail connecting the Z platform to the front rails.

24v Silicon heating pad, 300x300 aluminum plate with borosilicate glass and PEI on top.
Duet Controller with Due

I originally printed all parts with PLA on a Mendel then used the D-Bot to reprint everything in PET.

Still working on some enclosures for the electronics.
