Thanks! I will try it out and give feedback!

Does this help? You are right...I wasn't able to remove that grid-like stuff starting at layer2 😞 CE3MAX_V2_6_ALL.3mf

I post 4 screenshots here. Standard Profile with Tree Support 45° or 60° Overhand Support. 60° is plenty enough for this part. First two screenshots Layer 1 and Layer 2 with 45° Next two screenshots Layer 1 and Layer 2 with 60° All screenshots show, that the ZigZag support starts with Layer2. With 45° there are at least a few dots of support, the Layer2 ZigZag can bind to. With 60° Overhang Angle, there is ZERO support for the first layer to which the ZigZag cound bind to. Switching off Skirt to 0 Lines or turning it off completely doesn't help: https://www.reddit.com/r/ender3v2/comments/125yq7p/support_not_printing_on_first_layer_cura_530/

I think I now understand. Because of the angle it thinks this is mostly TOP, so it prints it filled.

CE3MAX_object.3mf

See attached picture. The back of the model is printed correctly. Two walls and infill. As you clearly see, there are other parts in the same layer, where yellow lines are printed. This is Top/Bottom, correct? Why are they printed...there is no Top/Bottom for MAAANY of the following layers. I attached the STL. Used Cura 5.6. Standard Profile. object.stl

Hi, is there a general guide as to how to tune Cura's printer profiles to get maximum speed with acceptable quality? I noticed that you can increase things like print speed to a point where the textfield turns red. Does this mean you can go to "yellow" and it is still okay? I assume print temperature should be increased as well since extrusion is much faster. I dialed up Print Speed to the highest value until it was not red. When slicing the print duration was much smaller. Then I also enabled "Print acceleration" and doubled the "Print Acceleration" value. When slicing, times did not increase. Very odd, no? Anyways, is there a good way to max out the speed of your printer while keeping the strength of the part mostly intact?

Sorry. I am an idiot. I meant Top/Bottom Line directions but then I changed Infill Line Directions. Duh 😞

The titel of the post says it all. Per model settings: changing Wall Line Count works. Infill Line Directions is just ignored. I am printing a single object and instead of changing the profile itself, I wanted to override certain settings via "Per Model Settings" > Mesh Type: Normal Mesh. Why is "Infill Line Directions" simply ignored? If I change it directly in the profile it respects the angles I am providing. Thanks, soh

Thanks! Can somebody suggest it. I have no Github account and am no developer - so have no clue as to what to say or where exactly to post. Cheers!

Would be nice to occasionally get a fixed Appimage with the current Cura version. Currently 5.4 Do you think it is possible? Highly appreciated. Some people are still on the old GLIBC

Thanks! I wonder how difficult and powerful the Add-On/Plug-In API of Cura is. Could one easily modify such things via this extension mechanism?

Hi, I love setting a different print speed for the first (initial) layer. I can even restrict this setting to just the first layer via "Number of Slower Layers" = 1 Now I want to do the SAME for just the visible Top layers. If I choose the setting "Top/Bottom Speed" to my preferred speed value it changes the speed of ALL the Top Layer (in my case 6 layers). 1. I only want to set the speed of the VERY TOP layer. 2. I also want to set the Wall speed of that TOP layer. "Top/Bottom Speed" only affects the area within the walls and not the walls itself. Similar to "initial layer speed" can I somehow set the "final layer speed"?

I experimented a little and it seems to be optimizable by keeping the branch distance and overhang angle value similar and high. Does anybody have other suggestions? Thanks!

Nobody has a clue?

The title already gives it away: How to encourage Tree Support touching the build plate to reach far away parts (and avoid support touching the printed part). I don't want to select "Touching Buildplate" since this will just leave out important support when it cannot reach an overhang that needs support. I would rather change my settings, that as much support as possible is touching the buildplate. Thanks, shoe

Maybe you should add a feature in Cura if a certain model is not listed to add one OR be forwarded to the Github Issue where the community could work on the new profile together. That way Cura could add the profiel in the next release and mark it as "Early Bird" or something.

When I bought my last new printer it took 1.5 to 2 years for its profile to find its way into Cura. Before that, I copied a different printer model of the same manufacturer, with the same print bed size and manually adjusted it a little bit. During that time I was always wondering, if the community couldn't throw together a little BETA profile program that offered me to side-load a proper profile for my printer into Cura? Or if the Devs could just simple add a profile (mark it in the list as Early Bird, ALPHA or BETA) for my printer which would be 10 times better then what I came up with. Also it would make setup so much quicker! Hence my question, shouldn't we make this much quicker? Why force people to manually tinker around if they buy a printer that is not in the list YET. Even popular brands take forever.

No. The print surface is good and everything works. Usually it just works. Still, in few cases it breaks. Maybe just a little dust that makes a corner of the model not stick. Then this sometimes snowballs (since parts are close together) and the filament-spaghetti of one part disturbs the other parts. The point is, I happily wait at the beginning of the print a few minutes for it to print ALL outer walls. This is super quick! What takes time is the infill. I don't want to wait over an hour for every object to finish its first layer. Thanks! @GregValiant I will look into the workaround! You truly are the king of workarounds! Did you try it yourself? Maybe you still have your three files, so I could look at them?

P.S.: I already tried fusing all objects into one. It works. One STL with all the parts inside. Still, Cura, figures out that we have many "loose" unconnected parts and prints them one by one and not ALL the walls first. I would probably need to physically connect all parts in order for this hack to work.

I wonder if I am the only one who sees a huge benefit if this were possible?

Hi, I print huge numbers of simple models (all 1mm high, 100% infill). If the print fails, it fails in 100% of the cases because the first layer has a problem for one object. If it fails, the root cause is, that the two outer walls detach immediately after they are printed. It's immediately obvious. Sometimes only this one object fails, sometimes its surrounding neighbors and sometimes the hole print fails and I only notice when I return 10 hours later. The problem is, to make sure the print is a success I have to wait until it printed the whole first layer. Why? Because it prints the walls of the first object and then prints its infill. This takes up to 2 hours. If it would print the outer walls of ALL objects and THEN the infill, I could monitor the print for 10 min. until the outer walls of all objects are printed. It they are printed solidly and there is no detachment, the print will be a success. Always. The question is, how to tell Cura to first print ALL walls of ALL objects before it prints ANY infill? Can another slicer do this?

With Poster you mean the Github issue? Can you post a link for completeness?

Thanks. Wasn't me on Github. I am not sure I understand everything you said about thickness being exactly .96 but at least I have a place to start experimenting. Cheers, shoe

Hi, I am printing a christmas tree (1.png) in vase mode. It has some cylindrical cavity (not really a hole) (2.png). In vase mode in Cura 4.13 (3.png) this prints as a hole in the bottom layers. In Cure 5.21 the hole is not printed (4.png) See screenshots. tree18.stl
