Please report here your LA1.5 fix test results.
UPDATE 30 Juli 2020
A new LA @wavexx version to improve LA1.5. It is based on https://github.com/wavexx/Prusa-Firmware/tree/la15_acc_fixes Please also try Report: Retraction test results to see that the BETA didn't break anything there.
UPDATE 22 June 2020
After the feedback on FW391-BETA-3459 @wavexx implemented another fix. It is based on https://github.com/wavexx/Prusa-Firmware/tree/la15_acc_fixes Please also try Report: Retraction test results to see that the BETA didn't break anything there.
- [G] Check for gaps at seam and other places 0=big gaps 10=perfect seam
- [V] Check for vertical lines, good to see at arcs 0=very 10=not visible
- [A] Check for overall best result 0=bad 10=best
Use the 3mf and gocde files in zip below. Speedtest_simple_25mm_every_5mm_different_speeds.zip
Or with also with temperature changes: starting at 215°C and increasing by 1°C. You may need to change the new temps depending on your filament brand. The idea behind this is to get the same "glossiness" at different speeds, as normally with increase speeds the material "glossiness" changes.

Every 5mm the speed changes

Custom brims using modifiers make a lot of sense. And would be easy to use to create "ears" where needed (just add a cylinder!).
I'm currently adding parts to improve adhesion where needed, but since this causes the first layer to be sliced along with the extra parts, the perimeters will "bleed" into them, making them harder to remove.
I know I can get mouse ears by adding a cylinder but I don‘t like this solution as this will also change where the perimeters are running (its rather changing the geometry of the part than having a custom brim somewhere). After removing them it gives a oddish look to the part
I often have several parts on the bed but only one or two need a brim. It would be nice to be able to add a brim to only the objects that need them.
Brim blockers have been requested already in https://github.com/prusa3d/PrusaSlicer/issues/3554
@GeekDad63 Brim per object has been requested in https://github.com/prusa3d/PrusaSlicer/issues/286
@nils-kal How do you expect a
possibility to place custom brims with a modifier.
to work?
For helper objects acting as brim you can check the Prusa Forum. e.g.: https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-how-do-i-print-this-printing-help/how-to-print-brim-ears/
Came to post this request. Hopefully it does get completed at some point. This would make things easier for a lot of my models.
I need this feature as well. I want to leave a print job with only some items that need the brim. Others definitely not, for cosmetic requirements.
Add me to the list of users requesting brim for only certain models! Thank you so much...
I would like to be able to enable a brim for selective models on the build plate too.
Would be nice to have an option to selectively add a brim for some items on the build plate, but not others.
Here's an example where it would be useful to add modifiers to selectively block brims. Here, there is close separation on the interior of the print.
+1 from me. I need to print narrow pillars that are as wide as the print bed is. They would need a brim to make sure they don't warp, but I cannot add them, as the brim would be outside the print bed at the sides. If I could add a blocker to these sides and still have a brim on the remaining two sides, that really would help a lot.
this would be amazing to be able to easily make production files with multiple parts
This item is about brim blockers (already requested in #3554) and custom brim, not about brim per object (requested in #286 and implemented in 2.4.0 [1]).
Please clearly separate feature requests and avoid +1 comments (use :+1: under the (initial) post instead). That way it will be easier for the development team to follow the discussion.
[1] See release notes of 2.4.0-alpha1, look for Brim and skirt enhancements.
Hello
Could definitely help a lot for "print in place" , or "flexible" models ... to get the benefit of the brim , but not blocking the "articulated" parts ( see the yellow arrows in the picture )
Yes, please.
Just an example. having narrow edges i would like to have also an inner brim, but do not need it on the circles.
Some of the posts in this thread are older, however this has been possible in PrusaSlicer since Sept 1, 2021. for those that posted after that time.

Hello Snuff1eupagus
2021 in Prusa ? What was the version of Prusa that had this option ? I remember I had to go to Super Slicer to have this
@cryoglobe it ended up just being a matter of knowing how, Prusa gave this to us years ago, this user has shown how to do this, and we have been able to since PrusaSlicer 2.4 alpha 1
Hopefully this will help you. watch the whole thing, it's good stuff.

I learned a lot from this, I hope to see more from this guy.
