The bed is set at 65C but it measures closer to 100C on my infrared thermometer.

So I tested the one wall prints at a variety of temperatures. 244, 240, 237, 234, 230, and 227. Things didn't really break down until I got to 223. The other prints were substantially the same, with slight variations in the puckering at the corners. If I did a few more runs of each maybe I could ...

The single wall test (no retraction) seems to start out well then goes off. More substantial prints like the ...
