@jonnyyeu I’ve updated my firmware and used 4/1/2 for my splice settings and I’m still having issues. The only significant change seems to be that I’m now getting error code 134 instead of error code 131 when I try to print. I’m assuming that’s because of the new firmware. The quality of the splices is inconsistent. Compare the spliced parts in the attached picture (excuse the less-than-ideal picture quality, I’m having to use my phone for this). The one one the right looks the way I’d expect it to look, but the one on the left has a very thin spot. Both of those pictures are using generic PLA with the same settings. This matches my previous experience of most splices being fine, but getting unexpected failures halfway through a print.
