Download and study the Construction Manual (47 pages) as it has all the pictures, drawings and comments for building this Printer. I may or may not reply to comments. There may be typos, spelling errors and omissions.
Print area is 280mm x 280mm x 230mm high.
Also you can make your own variations to this Printer.
0.3334mm layer, 0.50mm nozzle
Suggest you print X & Y Carriages with ABS as they are near heat. I used all ABS as I think it dresses easier than PLA.
Holes sizing will be needed and some other parts depending on you print ability.
I design this thing using AutCAD and use Publisher, Excel and Adobe Acrobat to publish it here.
