Print Bed PRoblems Part2

Hi after I have now unclogged x and y which I did once with a cold and once with a warm printer I have to realize that after 2 cooling cycles overnight it starts to suck again. The cold decompression had only made the whole thing worse. Preventively decompressing with a warm enc had top results with the first print. Now after 2 overnight cooling cycles it starts to go to shit again. So the printer turns out to be more and more a piece of junk for what I do with it. I have insulated the enc and fitted it with aluminum plates instead of the permeable acrylic so that I can get about 70 degrees into the enc with ABS. I only print with industrial materials and my own constructions do everything perfectly. The ABS PA12 and other types have a much higher glass transition than what you can buy as printer material. With ABS it is already 105 degrees instead of the usual 90 degrees... Therefore, I need the significantly higher temperatures in the enc, which means that the coefficient of expansion between the aluminum and the steel of the rails is simply completely out of control. The only thing left for me to do is to completely redesign the printer with a lightweight steel construction like my own or to get rid of the shit box and build one myself like the small ones because I no longer know a solution.
