Your time and money is worth more than trying to make some open source diy kit printer do what you want. Bambu has body slammed the market with printers that work.
Get a H2S or X1C, run it in lan only mode if you're paranoid, and don't look back. H2S is a better option for your material choices.
My comment will probably get flamed because I'm not saying Prusa makes the best printers and only support open source, but do you want a tool that makes things, or do you want to waste time baby sitting your tool trying to get it to do something others can do out of the box.
I WISH my machine was open source, but the reality is it's not. It's like asking what mill to buy, but rulling out HAAS and Bridgeport because you're ok with trying to machine around crazy slop.
