Due to my schedule I might not be able to get around to this until the weekend. I think there are some errors in the yaml though, in a quick glance I believe I saw a "Raw" instead of "Raw Resource" somewhere, I could be wrong.
There is also a script that can be used to get screenshots, but it makes use of Linux macro and screenshot tools so it likely wont work on windows or macos.

Additionally we have these scripts https://github.com/AsherGlick/ResourceCalculator/tree/master/resource_lists/minecraft/scripts/jar_extractor which can extract the recipes from the .jar files. You can use them to validate your recipes are correct. Also please be sure that the resource calculator build process does not have any warnings, as it will tell you if there are any issues in the yaml formatting.
