Speed difference between a kit MK3 upgrade to MK3S+ and a factory built MK3S+
Several years ago I bought my MK3 kit. Later upgrading to a MK3S and finally MK3S+. I decided to go all the way to a MK3.5 with MMU3. My MK3S has 88 days of printing.
I had an idea. Why not buy a high mileage MK3S or S+ and retcon it to a custom MK3.5 MMU3. Great idea, so great in fact a scored not one but two MK3 printers for the price on 1 new MK3S+. A MK3S and a MK3S+.
The MK3S is well used, has had no or limited maintenance. IT will be retconned for my project.
The MK3S+ is a jewel. Not even a month of printing use. Has not even had a full spool thru it. It was a steal.
It runs circles around my upgraded MK3 >MK3S >MK3S+. It is extreme fast.
Same firmware 3.13.3 (flashed it day one), same Einsy 10a, same custom print settings.
Benchy was done in 1hr 23min vs 2hr 16min same everything.
I have not found any explination why. Am I missing something?
