diy 3d printer design verification

[super7800]

if anyone wants to follow the project further, here is a reddit post i made where people have been helping me out: https://www.reddit.com/r/3Dprinting/..._verification/

here are some updated pics for those interested:

the volume is 500x500x~1000mm

the z-axis motors and dual ballscrews are not pictured. they are a set of nema 23

the x/y is now a corexy design using 15mm gates belts, two 600mmx12mm supported rails, and a 700mmx12mm single linear rail. its driven by two nema 17 steppers.

here is a picture of my roughph wiring diagram: https://postimg.cc/WhWTBj7h

i plan on using 7 (yes 7) watercooled extruders, and using air instead of fans to blow air onto the part, since this will be completelly enclosed. all wiring excluding water will be enclosed in dragchain(x/y using 10x20, z using 10x10).

for more pictures/ details please see the above reddit post link.

as always if anyone sees any problems with the design, or wants to suggest anything, your opinion is welcome. manny of the parts have been ordered already, however.

thanks!
