Thanks, Michael and Eric.
I am attracted to the HercuLien design’s Z axis system – it seems very stable, though possibly too well constrained for a smaller build.
I am also considering a Delta printer for my first build. The DC42 Kossel build looks like a pretty stable frame design, and it seems reasonable from a cost perspective.
I do not have a printer at the moment. I do have a milling machine, a drill press, and a small cnc mill. I could likely use a friend’s printer to make parts as well.
I enjoy building complex projects more than I do operating them, so I would rather build from scratch than build a kit, and I would rather build a kit than buy a printer – even an expensive one. I am looking for a design that can do very fine layers, print about a 10 to 12 inch cube, and work reliably with high temperature, exotic, and flexible materials. ABS is a requirement, Acetal, Nylon, and Polycarbonate would be nice. I will probably need to enclose and vent the printer.
What are the issues with mechanical stability in these CoreXY designs?
How difficult is it to do manual bed leveling? Is this as important as the controller’s compensation for bed tilt and warpage?
What are typical build volumes and machine sizes for Eustathios and HercuLien?
Are there any reasons other than build volume, ease of using a direct drive extruder, and enclosability to go with a CoreXY build over a Delta?
