New version of my S3D profile
It took me weeks of tweaking to reach this new version and I've got what I think is a very good general purpose base config.
You can find it here on github
or download it below.
Since everybody likes some benchy here it is
(I'll post more soon).
How is it made and what's the difference with the official config?
The 3d printer firmware received various updates and Slic3r Prusa config has been updated multiple times. Unfortunately the S3D settings haven't been updated to reflect the new features, so the official config just seems outdated.
I have taken the official settings and compared them with the latest Slic3r PE. Then I started printing dozens of models altering various parameters until I reached what you see here attached. Some parameters are fine-tuned in 0.01 increments, others by looking directly into the firmware source code.
Important Note for everybody
Remember that each model is different and may need different configuration. What I'm trying to do here is a good middle-ground to get you started. For example I could further improve the quality of the 3DBenchy print but we wouldn't have a general purpose profile anymore.
Also bear in mind that each Prusa is slightly different, especially if you built the kit yourself. The maniacal level of customization I did on the settings also means that they are very much fine tuned to my machine
You may need to adjust some of the parameters, notably: extrusion multiplier, extrusion width, retraction values and speeds.
Tests have been made exclusively on PLA and should work flawlessy from 0.1 to 0.2 layer height. ABS is supported but not tested as much as PLA. I would need more Prusa printers to speed up the configuration process...
Notes for experts
is set to 95% mostly to prevent blobs. I noticed that a slight underextrusion produces better tiny details. We have 0.44 as extrusion width and 25% as Outline overlap so we should be fine. Please note though that this value very much depends on your 3d printer and you may need to lower/raise this value accordingly.
I've set Support Infill Angles
to 0 and 90deg. This is a personal preference, normally they are not crossed but this way they better stick to the plate, especially if they are very tall. Of course, revert to standard supports if you wish.
Prusa settings have default speed to 40mm/s while Slic3r PE is set to 60mm/s, that is quite a difference. I've configured everything for the highest quality possible at the highest speed possible, that means that lowering the Default printing speed
can't only produce higher quality stuff. I believe Prusa settings are very conservative because in S3D it's very complicated to fine tune per material and per nozzle size, so they possibly just set a safe value.
As much as I tried I still couldn't find the perfect retraction parameters. You could disable retraction altogether to put less stress on the machine, but it seems that best results are obtained with a good dose of retraction. I'll keep experimenting but it's an extremely time consuming task and it has to be done for each material.
Other improvements might be needed in the support material section, bridges and acceleration.
PLEASE help me improve these settings!
I've put many hours and meters of filament on these settings. Please help me improve them by discussing the various parameters. I'm just an informed novice, I'm by no means a 3d printi expert. If you have any suggestion please do share! If you think some option should be different let's talk about it!
