MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Thanks for your great design I will give it a shot soon.
I just wanted to leave a note about klipper firmware and you might consider taking it into your thing details or not. I think klipper firmware is maybe a worthwhile upgrade. Nevertheless from my point of view it should be mentioned that this also makes your printer somewhat heavily dependent on the functionality of your UART/USB connection. I have a Raspberry Pi 4 attached to my Ender 3 and as some other guys I ran into the problem of sporadic interruptions (same as described here: https://github.com/KevinOConnor/klipper/issues/1919). Throttling the connection speed and hoping it will work sounds not much of an improvement to me. Thus the print speed is directly related to the UART speed - I think it would be better to have a better CPU installed on the board. There are approaches to this:
