I tried Arachne on one small print, but after printing I noticed that the support interface was not created so the overhang was bad. I double checked the settings and it should have been there, but wasn't. I think I'll wait for Arachne 2.

Hi all,
this is one of the best/most important news for my daily work with Cura. Juggling and fine tuning line widths to get cleanly printed, solid walls is one of the most time consuming and infuriating tasks for me, even more so because every other slicing software seems to be able to handle this with ease (and for years already, might I add).
I print a lot of parts for customers, so I don't really have influence on wall thicknesses. Moreover, I'm using horizontal offset to make parts more precise which nullifies any design guidelines ("use a multiple of X as wall thickness" - doesn't make sense)
finally, I just hate it when my printer tries to shake itself to death 🙂 it might work on Ultimakers with their mechanics, but it just doesn't seem healthy. And I've had the rods fall out of the clips already....
is there a rough timeline on when this might be implemented into the main release?
best, Niklas

Hi,
I tried CURA Arachne Alpha on small parts for hausemodels 1:100.
1. open in Cura Arachne an existing Project (Cura 4.8)
2. used standard values for "Variable Line ....":
3. Sliced with the same parameters I used for Cura 4.8
The result with CURA ARACHNE Alpha looks like this:
Same sliced with CURA 4.8:
Attached a 3mf file created with CURA ARACHNE Alpha.
I have to play with extrution and other parameters as soon as I have time.
Kind Regards
Raimondo

Hi, first of all, it is a pretty good update, I've really enjoyed it - until I stuck with this model
So, I've printed the model and found out some strange artifacts on the surface, when I tried to find the option which created it - I found Variable Line Strategy, and on the "Center Deviation" option, at first sight, the problem was solved, but it creates another - hole between walls. When I switched back to Cura 4.8 - there were no problems on the surface
Long story short - ATM it's pretty tricky to print this model clean on the current Arachne version

Im basically using the default settings with an UM3 on arachne alpha.
There are strange things happening, when the infill is at a narrow area there are inserted mini travel moves (e.g. these blue dots in the circled area) that cause the printer to nearly stop moving (I'd say it's below 1mm/s in these areas). Regular infill works, it only happens when the infill area is quite small.
An option for the "order inner walls by inset" that affects only the first layer would be good. I had some issues on the first layers with an object with many holes, the printhead combed across everything and pulled some of the printed single lines away by doing so.
Overall I like the strategy the slicer uses, it's especially useful for small objects the have areas where walls are not a multiple of the line width. I made some replacement caps for some connectors that came out perfect with a 0.25mm nozzle, though they have walls that are only 0.4mm wide.

Ohio State is up by 3 touchdowns at the half and an Arachne print has finished.
Same model, same settings, mirrored using Cura. On the left we have Arachne and on the right is 4.8.0. The printer is an Ender 3 Pro.
There is some Z-banding on the Arachne print up to about 1/2 way up and then from there to the top they are really close to being identical. The 4.8.0 version was printed first. I will let the Cura Team analyze the banding. The parts were printed one after the other. The color makes them tough to photograph.
The movement of the layers of the base of the Arachne version went down oddly. One loop on the right hole, one loop on the middle hole, and one loop on the left hole, then start over on the right hole, until the inside wall was built. The outside walls went down normally with 3 loops around each in turn before moving to the next hole.
Those of you who know about such things will recognize that the Honda Goldwing in my profile is fitted with dual Weber IDF carburetors and topped with velocity stacks. These are my take on old style Stromberg ram stacks from early V-8 drag racers of the 1950's and 60's. I thought they would make a nice change of pace at shows. Nobody will ever notice the banding since a light must be held at just the correct angle to show them. My luck will be that the sun is at just the right angle when the judges come by.

after trying a couple of prints, in terms of quality, 4.8.0 produces better results if you disable 'fill gaps between walls' and 'compensate wall overlap', which i have had to do for a long time as they are not good.
Clearly Archane looks to address the issues these settings have, but for now there are many surface artifacts with Archane and in reality it's not much better than 4.8.0 in terms of visual quality with these problematic settings enabled.
Obviously once Archane does what it is meant to it will fill any gaps between walls (should make stronger prints, although that's debatable if those gaps make much difference) and corners etc will be sharper as the overlap compensation will be sorted out. However for now i would rather put up with gaps and rounded corners to avoid these surface artifacts.
Looking forward to trying another build !, i am sure it will be great in the end
