Knowing the localization and the interaction of everything with each other would have helped me a lot and certainly saved time.
I guess this is the disconnect. I've assembled one, but I don't feel like assembling one necessarily conveys this. The instructions just tell you which part to attach to which other part. It doesn't explain why much of it is important or how it functions.
The other difference is that I haven't upgraded any. I have some MK3S+ printers that I are likely to remain that way since the upgrades are so expensive and the process so laborious.
For personal use, I'm waiting on the CORE One from Printed Solid but it's only available for education, government, etc at the moment.
I was looking through some old vinyl in a store yesterday and found an album from the 50s or 60s called Songs Everybody Knows and I didn't recognize a single song on the list.
