I already have a Prussa style printer, but want to move up to the stability of extrusion. I really like the OpenBuilds concept and want to make an X/Y table style printer with the crane Z setup kinda like this: I was thinking that if the hot end stayed stationary (only moving in the z axis) it would be more accurate. I could move away from the bowden setup since all that mass wouldn't be moving around. I know that the bed would be moving on 2 axis now and there is a lot of mass moving the aluminum plate / heater / printed object....would this be more / less accurate than having the X axis on the crane portion of the printer? Here is a video of the x/y being built: I searched around a bit and I haven't found any actual builds with this style. Any comments?
