I have a print that its going to take about 8-10 hours, and I need to make about 10 of them. I've been looking into ways to speed things up, and ran across this video: https://www.youtube.com/watch?v=3kW9SnK4LKc
At about 9:30, he's discussing his speed settings. The thing that really jumped out at me was he's got his regular speed set at 100 mm/sec, but his slicer allows controlling infill speed as well, and he's got that set at 250 mm/sec. or 250% faster. I'm not even sure my printer can go that fast...
I dashed downstairs & looked through all of the speed & infill settings I could find in S3D. As best I can tell, there is ZERO control on basic infill speed. There is only a setting for solid infill underspeed, which doesn't really help.
I've currently got my infill set for 20% using a rectilinear pattern. I took a look at "fast honeycomb", and even though the infill percentage was still 20%, the holes in the honeycomb are significantly larger. For a smaller test print I have set up, the print time goes from 1 hour 16 minutes for the rectilinear infill to 1 hour 24 minutes for the fast honeycomb. It turns out "fast honeycomb" is the SLOWEST of the various infil pattern options, including plain "honeycomb".
1) Why doesn't S3D have some capability to control infill speed? Or is it buried someplace I didn't find?
2) Any other suggestions for speeding things up?
