Thanks for the video. My printer came with the MK10, but I saw some people saying the MK8 is actually better (less stringing, and also cheaper replacement parts). Have you done any comparison between the two? Any insights on which one you prefer? I ended up getting an all metal hotend for the MK10, but still curious about the differences in quality / performance with the MK8.

+aardvarker The stock MK10 design uses a PTFE tube as the thermal barrier within the filament guide tube, resulting in a reduced melt rate of filament compared to the MK8 design with the stainless thermal barrier tube. You can see this during filament loading, where the same filament at the same temperature will flow a little bit better on the MK8 design. In terms of stringing, there should be little difference between the two once retraction and temperature are properly adjusted. The MK10 hotends do run a little hotter than MK8 hoteneds for their indicated temperatures - so the MK10 may be prone to stringing if you don't lower the temperature. In terms of parts costs, there are far more MK8-compatible replacement nozzles out there (due to its M6 thread which is a very popular thread size for a lot of printer builds. We sell our high lubricity wear-resistant MK8 and MK10 nozzles for the same price though.
