I fucking love it! I have been there so many fucking times to the point of putting a hole in a wall. Best part is I’d give up walk away for a month or so then literally turn the stupid fuck on and press print and it would print just fine. I just use glass on one printer and carbon fiber on the other. I had pei once threw that shit right in the garbage. A good scuff with 80 grit sand paper on both and wash off with rubbing alcohol. I did have an issue once with a bent touch probe that would fuck my z offset so the first layer wouldn’t actualy be low enough.
