Profileinator - By David Durant
Recently I posted about the basic usage of Dave Durant’s Profilinator, a program that will calculate the best print settings for your 3D printer. In order to get you started with how to use the program I left out two amazing features of this program. Today I’d like to cover the first of these sweet features.
As some of you already know or might have guessed, his program can provide a range of reasonable print settings, not just a single recommended setting. If you want to see a range of print settings all you need to do is specify different values for the minimum and maximum for Feed rate, Thread height, and Thread width. Dave’s program will then solve for the appropriate flow rate given those settings.
How is this helpful to you?
Well, perhaps you may not yet know what settings you want – so one particular set of setting values isn’t that useful. Perhaps you really like thin layers? Perhaps you’re not sure about how thin or thick you want each extruded thread to be? By specifying a lower minimum and a higher maximum for the Feed rate, Thread height, and Thread width you’ll get a list of every permutation of these variables with the appropriate Flow Rate. Now you can experiment freely printing using any of those settings and find out first hand which layer height and which thread width you really appreciate.
Based upon your particular hardware and configuration, you may discover your robot’s limitations. After printing for a while, you’ll get a good feel for how fast you can run your robot’s XY platform. Once you know an optimal feed rate for your robot then it’s a matter of picking other settings.
Rather than spending your time filling up your home with calibration cubes, trying to discover your optimal settings – using the ranges of settings from Dave’s program you can choose which of a range of good settings you most appreciate.
Dave mentioned during our conversation that he was able to reduce either the layer height or thread width without a big change to printing speed – but that reducing both at the same time would increase print time.
