Totally agree that CraftWare has good gcode preview!
We “normally” show the slicing settings you used at the top of your gcode file (in a comment), but that got broken right before launch. We’re going to fix that up.
I agree that being able to see what slicing settings you used in previous prints is super important. Like what @Soul said, I think that a comprehensive tuning suite is a really good tool to get you to settings you like, but doesn’t address the tweaks you do along the way in a project.
We’re thinking about some pretty powerful project-based features that should help mitigate these problems effectively. This is a longer-term feature, and we’re not quite ready to share the details because the ideas are still evolving quite a bit. I’ll share later on when we are more clear on what we need feedback on. Suffice it to say there’s some really cool stuff we want to do to fix this.
As for directly importing gcode to look at, it will take a little longer. Right now the print preview in the app itself is coming from the step right before the actual gcode is generated, so we can’t preview actual gcode as of right now. That’s a feature we really want, though, as it’s one of the main reasons that I have to keep Simplify3D around…
