Here is my concept for a decent sized CoreXY printer. Target build volume is 300x300x300.
Questions I have for those that are more experiences with these systems
Linear Rails for X and Y axis - 12mm or 10mm?
X/Y rails that will support the Gantry - 12mm or 10mm?
Z Axis rails - 12mm or 10mm
The external frame is being CNC cut from 4mm Fire Rated Alpolic. The 4 vertical sides are being cut as 1 piece then folded to exact inside dimensions then the corners epoxied with industrial epoxy. This puppy will be rock solid. The top an bottom pieces will be bolted on angles that attach to the vertical box. The material being used is a brushed aluminium/stainless steel look. Prototypes for the corner blocks will be printed, then once fit is verified possibly will machine from aluminium blocks.
All axis will be run from one Nema 17 (76 oz in). Electronics most likely will be Ramps 1.4, Mega 2560 and DRV8825
I invite any critisms or advice to improve the design. Image is attached
Edit: Guess I should provide some dimensions... The box external dimensions are 588mm width x 588mm depth x 550mm height. The perimeter X/Y axis rails are 500mm (2 per axis), The individual X and Y axis rails are 475mm each (1 per axis), The Z axis rails are 400mm each (4 total). The 2 lead screws are 8mm.
