Cleared a backlog of eleven models in one sitting with the new batch drop

The batch conversion alone fixed my Sunday evenings. I print a lot of gridfinity organizers for the garage, and I had maybe fifteen STLs sitting in my downloads folder from a few weeks of browsing. Before this update I'd do two or three at a time while watching TV because the waiting was so tedious. Last weekend I dragged the whole stack over and had everything converted before my coffee was cold. The drag and drop change is what surprised me most. I'd gotten so used to right-clicking and saving files into a staging folder that I forgot the browser would just try to open an STL if I dropped it anywhere else. Now it feels like the tool actually expects files instead of tolerating them.

I tried the preset import on one thing and my experiance was mixed. The settings matched the original fine, but the supports were laid out for a printer with a bigger bed than my Adventurer 5M, so I had to reposition them anyway. Still useful as a starting point, I just wouldn't assume it transfers perfectly to every machine. The one hour window for grabbing finished files is also a small mercy. I have a habit of starting a batch and wandering off, so I've lost more than one converted file to a short timer in the past.

I've been leaning hard on that preset import since the update, though my experience with it is a bit mixed. Pulled the process settings off a articulated dragon print someone shared and it came in with way more supports than I needed on my Adventurer 5M. The designer was probably printing it on something with better overhang performance, so I ended up editing half the settings back down anyway. Still faster than guessing from scratch, but I've learned to eyeball what comes in before hitting start.

Where it's genuinely saved me is with vase mode stuff. I do a lot of spiral vases for gifts and the layer height and speed the designers pick acutally matter there, so importing thier settings and just swapping in my own filament profile gets me a good result first try most of the time.

The file retention window is the sleeper feature for me. My kid has a habit of grabbing my laptop mid-print-prep to watch videos, and I've lost converted files twice before because the tab sat idle. An hour is enough buffer that a distraction doesn't cost me twenty minutes of re-doing everything.

One quirk I hit: if you drop a mix of STL and 3MF files on the home page it handles both fine, but the preset import only shows up when the source had settings baked in. Took me a few tries to figure out why some models gave me that option and others didn't.

I don't buy that the preset import is 'still useful as a starting point.' If I pull settings from a model designed for a massive industrial printer, and I have to spend half an hour moving the entire support lattice just to fit it on my normal setup, it’s not a starting point, it's just another mess to manually edit. The time saved by avoiding the initial guess is completley eaten up by the cleanup effort.

I found that even when the core infill and wall counts looked right, the support placement was often so aggressive or so sparse that the resulting print was flawed. It feels like it introduces a whole new layer of guesswork instead of eliminating it, wich is pretty frustrating.
