When I change the default printing speed or the X/Y movement speed in the settings, it doesn't actually improve the estimated Build Time. I think this is because Simplify3d doesn't know how fast my printer can accelerate (Klipper user, acceleration set to 10,000mm/s2). This is a bit annoying because I can't experiment with different tradeoffs in the Slicer.
What acceleration does S3d assume when calculating build times? Any suggestions as to estimating the impact of various speed changes?
