Thank for the PR but there is a bit too much here for a merge. Can you separate into simple clean PR's each with a specific purpose. I.e. keep blobifer and cut_tip changes in separate PR's.

Also this PR has picked up a lot of your personal settings that I'm not sure are the best defaults. Some are incorrect, such as the removal of tokens in the variables that are substituted during the install. (e.g. klipper dir).

Also with each PR can you describe an overview of the issue and how you have addressed it. This will make the review much easiler.

I'm happy to look at these if you can re-submit as described (btw: I'll likely bring in the original author of Bloblifer @Dendrowen to help since I'm not the original author of that particular macro).

@Dendrowen Is there anything in this PR that you would like to pursue. There were too many unrelated changes in the PR for me to consider, but I wanted to flag you before I close it out.

I agree that there are just many more changes than needed. Please clean up and restore default variable values before continuing.

Edit: I now see this is 5 mo old. Nvm 😅
