Hello Hippox. I'm sorry that you have been experiencing these issues and I wish I could help you out. However, do realize that the majority of users have been successful (with a minor problem here and there due to this being a work-in-progress build). Your expectations at this point seem very high and I can understand that but do keep in mind that this is mostly a non-profit 1-man project and that you are the first to report this ammount of failure.
In my experience, even with a stable build, I too have wasted more filament than I'd wish for only to realize later on what worked out best for my machine and for the project. Feel free to consult the (outdated) in-depth guide and the various settings posted across the project for different machines. Let me know if I can be of use as well with any tips or knowledge that may be helpful to you.
Lastly I would advise you to avoid remixing as it is against the current rules and may make things worse, especially if you are using Blender, which is not appropriate at all for parts with this tolerance.
Again, let me know if I can be of use for any problem you need fixing. Feel free to send me a direct message and have fun with the build!
