Total Print Speed substantially increassed

Hey Guys and Gals been away from the hobbie for a while and jumped back in this week. Using the Prusa MK3 and the PrusaSlicer v2.3.1 . All kinds of new features to play with WOW. But one thing I noticed is my total print times have GREATLY increased. For instance I sliced a Ignot file and the total print time was 21 hours and 41min, however my old G-code same file was only 5 hours and 20 min.  To the best of my knowledge I had never adjusted the default speed values. What has the newest updates changed that have caused my print times to increase so much? I printed some Naruto stuff for my son and same thing something i thought would take 6hrs MAX was taking over 16hrs. Any help would be appreciated. Again before and after to the best of my knowledge i have not adjusted any speed settings

Without knowing what settings you're using, it's hard to say. Save your current 3MF project file, zip it up, and attach it to a reply here so we can see your part & settings and give better recommendations. If possible, also provide one of your old "faster" 3MF projects for comparison. I can say that I've only seen speed improvements over time, but a lot may depend on your specific print. Also keep in mind that the slicer time estimates don't mean much if the settings don't match your hardware. Prusa improved the accuracy of the slicer print estimates over time.

@bobstro 3mf files zipped or not, is not permitted for security reasons. At least that's the error I am getting

Figured it out, I was using an Ultra Quality setting (.05mm) not the normal .15mm quality setting my print time is back to "normal". Thanks for taking the time to respond. Would have never imagined that .10mm would make that big of a difference. Also explains why the print looks so much better. Rookie mistake on my part. Thanks Again

Unfortunately, the printer has to move just as much for every layer, so every time you halve the vertical layer height, you double the number of printer moves. If 0.2mm isn't good enough, I'll sometimes tinker with 0.16 or 0.17 or using variable layer heights to try to balance the increase in time. Definitely check out the variable layer height improvements. In addition to improving quality, they can save print time by only using those lower layer heights where it'll matter.

Prusa has made some nice improvements to the printer firmware and slicer recently. Have fun playing with all the goodies!
