Jules,
you're right, I'm getting slightly better print quality at 205 and the support material breaks-off comically easily. It wasn't bad before, but this is ridiculous (in a good way). I did notice that small islands can break loose on the first layer at 205, such as the rings around screw holes. I'm running a PEI bed at 60 for PLA. For now I'm running a 215 first layer and then dropping to 205 at layer 2, seems to work really well. I'm sure I could get-by at 205 for the whole thing if I raise my bed temp, but my nozzle heats a lot faster than my bed and I print a lot of parts.

Thanks for the help.

cheers,
c

If small islands are not adhering well. A couple of things that can help are lowering first layer print speed. Make sure your first layer has sufficient squish. And print a thicker first layer. I print pla at 180.

For anyone interested, ordering the regular nozzle and specifying in the notes that I wanted the stainless steel one worked fine. Thank you Makergear.
