How to create an optimized filament profile?
Hello all,
Prusa has provided lots of great vendor specific filament profiles in Slic3r Prusa Edition, as well as some generic.
As a newbie I'm trying to figure out a repeatable, step-by-step method of creating optimized profiles for the filament brands I have been using (Matterhackers and Hatchbox)
What test prints, methods, and steps do you use or would you recommend for creating a brand/type/color specific filament profile?
Re: How to create an optimized filament profile?
Here's what I'm doing with Slic3rPE. You want calipers with 0.01mm resolution. I'm sure it can be improved, but this is yielding good results:
Some of this is overkill, but I'm finding it easier to create separate filament profiles rather than try to remember little tweaks.

After attempting to do the same (I'm sure many have tried) quite a while back I came to the conclusion that it is almost impossible to achieve.
And after trying many brands with a few different materials I have concluded there isn't a great deal of variation between filament brands of the same type of material. Once you have a good profile for one type of material it generally works pretty well for most others.
I wouldn't lose too much sleep over "optimizing" anything 🙂

Excuse me, but are you implying that there is little to be gained by printing endless little useless plastic boats and staring for hours at little 20mm cubes with high-precision calipers under varying light? Madness!

I think it's a worthwhile exercise to understand what difference the calibration makes, but you are correct that you'll soon find most filaments don't vary a lot. With different filled materials it matters more. In the end, having a handful of profiles is about all you need, and those are likely driven more by temperature variations. Unless you're printing precision-fit parts or tight screw holes, it's not something you need to obsess about.

I would never suggest such madness, to be sure. I think the best solution is to buy 10 Mk3s, write a python programme that keeps track of and outputs each setting change in gcode, then analyses each model under a SEM and finally reports findings back to the UN council on FDM filaments.

Find a brand you like which is consistent, and stick to it. That's the simplest way to avoid always having to recheck things, however many brands are very similar as stated above. I have so many benches, I could invade a country with them 🙂 Done with that.

This guy gets me.
