I played with my 317L a bit more on mine, and found some usable settings. I was doing ok at a TCR of 0.00265, temp limit of 220 F. I was playing with it there since I saw people having success w/TI on mods that only had nickel mode by cutting temp to around 170. That's when I had the (in my mind at least,) brilliant idea to double the actual TCR of the SS, and halve my target temp.
It came close, had to fiddle a bit more from there. I ended up at 0.00185 TCR, 270 F. I get frequent cut outs due to temp, but then it's at temp already and the SS seems to hold heat better than nickel wires did, so I inhale through the cut outs and I get vapor and flavor, just not much heat. Not for those seeking consistent throat hit, sorry.
The XCube II definitely suffers near edges of capabilities. Setting minimum TCR, or approaching the top of it's resistance limits, or even at the edges of the box's temp limits produced odd results in my playing. If you've a better device for the material, I'd recommend using it, but for me, this was at my price limit, and while I think it might get better with other wire materials from the beyond ni200 thread, the SS is a huge step up from nickel for me personally, and is still usable here with a bit of tinkering.
I am chagrined to say I think I found the source of some of my
really odd readings, and it was me. On inspection, my clone velocity has a set screw that doesn't tighten down all the way. One of the replacements fit a bit better, but the problem's on the post. I had resistance jumping around from that.

I guess that's an excuse to break out the only other dripping atomizer I own to try out though.
