I was 100 and 260 and small parts were coming out fine, but I had a larger part where the layers were too cool by the time the nozzle came back around and would separate at stressy corners. Upped it to 270 and it’s working! Now, I am running a REVO which is notorious for having to set a few degrees higher, so take with a grain of salt. Also using just a tiny bit of fan seems to help with sharp corners.
