I’m waiting for the upgrade kit, which does not include a new frame, so that that remains the same. The changes are in the bed, z-axis motors, I think the extruder motor, the hot end, the auto levelling, and some rigidity improvements where frame and power supply join. No new rods or frame. Whether that means it’s compatible with all previous i3 mods I don’t know.
I’ve just looked at some images of the steel i3, and visually, compared to the old Josef Prusa model, there is more room around the bed in the original Prusa i3 than the steel version. That implies Josef’s new bed might not fit the steel frame. What is the width of the space in the steel frame?
+1 for Josef Prusa’s original i3. His team is great. Fantastic friendly support, which is so important with your first printer, a great quality kit, and he’s just brought out the Mk II with auto levelling, E3D V6 hot end and a bigger bed with special surface! Superb results and long term support with his upgrade promise. Can’t recommend highly enough. And open for modding when you want to.
