Hi, Some pictures of my Openbeam CoreXY 3D printer. Print area: 200(Y) x 190 (X) x 190 (Z) Extruder : 0.3mm Constructed with 8 metres of Openbeam. Shaft sizes: 8mm dia. It does have a slight flex on the print platform - not an issue with most prints but looking at increasing the Z shafts to 12mm and using bigger linear bearing as there is a lot of weight with using 4mm glass plate. (Only glass I could get that was heat teated). Currently able to print objects, looking at adding a cooling fan to the carriage are to allow cooling of the filament.
