I know I'm using cheap filament and the answer is buy something better but... I use Overature PLA with the MK3 no issues for years. Even XL5T works fine but more issues than usual on our MK4s. Is it the standard speed on the MK4 is just to much for this filament? Prusa even disables the option to select overture filament profile. With so many setting to tweak, how can this specific filament be a posion pill.

Image shows the seem issue that I never have to think about on MK3s. I fixed the align issue shown on the right but then got a random seem issue shown on the left.

Any advice besides buy better filament and a filament dryer? Would you tweak retraction? Speed? Temp?

I teach a mix of technology classes that all use TinkerCAD at some point. We learn how to convert .png images to split .svg files to be imported into TinkerCAD early on. Previously my instructional material would direct students to pngtosvg.com to convert multicolor images. The best features were the color picker, simplify feature and most importantly, the option to download a split .svg file with registration marks in the corners. This made it easy to align the individual colors in TinkerCAD. The site was always a bit janky but recently it had major issues and is barely working.

Does anyone have an alternative site for converting image files into split .svg files with registration marks?
