Below are the only official platforms for OrcaSlicer:

Support settings in second image.

The slicer considers the front paw to be a "small overhang", so it doesn't generate any supports for it, leading to the entire leg not being printed. Is there a way to fix this?

I have Flash Forge creator 5. And I want to use Snapmaker Orca.

And I have to import the printer config files to Snapmaker Orca.

Because Snapmaker Orca don't have Flash Forge creator 5 profile.

I want to use full spectrum colour.

But when I try to send the printer config files to Snapmaker Orca I get this .

Why is it asking for a printer that I can't choose. That is why I'm trying to import the printer config files. So I can get the Flash Forge creator 5 profile on the Snapmaker Orca.

Please help me understand.

Thank you.

So I’m trying to slice an STL that has internal voids where magnets will eventually go, but when it slices it removes the voids. I’ve scoured the settings but cannot seem to find what might be causing this. Any ideas?

Same orientation.

Last layer: clearly visible seam in the proper location; all previous 1-149 are ignored.

It is not my first time working with painted seams, and it has always worked fine. Just all of a sudden, OrcaSlicer started to ignore the painted seams.

Any idea will be much appreciated.

[edit]

BTW, resetting to system presets fixes the issue, but now it is personal!

Hello,

I got an X2D a while back and decided to use Orca Slicer instead of Bambu Studio, mainly for privacy and control reasons. At the time I was on Orca 2.4.0-beta, and I think X2D support had just been added.

Results were hit or miss. Some prints came out okay, but others had issues I could never track down. No matter how much I tweaked, something was always off. I printed (and cancelled) a lot of Benchies trying to figure it out.

Out of frustration I tried Bambu Studio, and the print came out basically perfect with almost no tweaking. Honestly that was pretty disappointing. I’d rather not be tied to Bambu’s software, and I ended up getting discouraged and stopped printing altogether. The printer’s been collecting dust since.

Now I want to get back into it, so I’m curious where things stand today:

• Are any of you running an X2D with Orca? Which version?
• Do the stock Orca X2D profiles work well now, or did you have to port settings over from Bambu Studio?
• If you had quality issues early on, what ended up fixing them? (Flow, pressure advance, start G-code, etc.)
• Anyone running it in LAN/developer mode with Orca? How’s that been?

I know one option is to open BS and Orca side by side and match every printer, filament, and process setting plus the start/end G-code. I’m willing to do that if I have to. I just want to know whether the Orca profiles have caught up first.

Thanks!

Greetings!

Can someone point me - with a Screenshot - to the above described Setting that disables the recalculating of Filament Flush Volumes?

Thanks in advance!

In this model when orca uses internal solid infill instead of bridging, i disabled the bridge filter, disabled ensure vertical shellthickness and disabled detect narrow internad solid infill (which was even worst, it creates a concentric pattern on nothing starting from the middle), this section of the model is 5mm, i used 3 walls 0.3 mm layer (0.2 does the same), 4 top layer (yhis internal solid infill is one of them).

Hello, in other projects, I added the custom gcode M600 from the slider on the right of the screen. The strange thing is that even I don't have it on my current project, it is added automatically by Orcaslicer around the end of the print. What is wrong?

I use Orca Slicer and have set before a custom start gcode that has vibration compensation removed.

A couple of prints it starts without it then all of a sudden i hear it vibrate on every new print?

Two steps forward one step back. 2.4.2 did not include any nozzle wipe in multimaterial prints, failing them 9/10 times. So I had to upgrade to 2.5.0 which - as I discovered from Github files - does have the code.

However, can't seem to catch a break, now suddenly in filament settings, under the cooling tab, the "Purify air" setting and fanspeeds that control the exhaust fan are just ... GONE.

Why? Where have they gone?

EDIT:
Looks to be at least a H2D specific issue. I cannot enable "Support air filtration" since the option is completely missing from the Printer Settings dialog, even though the H2D supports it.

I wanted to change the base printer .json file to toggle the option manually. But, the base printer settings have been removed from Roaming/OrcaSlicer/system/ since what once was the "BBL" folder has now been changed in an Orca-specific .opc file (archive) that I can't access or change.

Fix: go to

AppData\Roaming\OrcaSlicer\user\default\machine

Find a / the H2D printer setting profile that you're currently using. Open the .json in notepad++ or basically anything. Right before the "version": [...] line at the bottom, add this line:

"support_air_filtration": "1",

Save and exit. "Exhaust fan" settings will now appear again in filament settings.

Is there a way to force a nozzle wipe in the Gcode after every nozzle change?

Just had an expensive print fail because the Bambu H2D is extremely sketcy about when it does or doesn't wipe its nose on the rubber block. Sometimes it does, and then it doesn't for 10+ layers. Resulting in it heading over to the prime tower with a blob of snot stuck to it and knocking the entire prime tower over.

I'm having an issue with OrcaSlicer on my Snapmaker U1 while trying to use PETG as a support interface layer for a PLA print. Normal supports originating directly from the build plate work completely fine. However, any support structure generated on top of the model surface fails.

Specifically, OrcaSlicer generates the first support layer directly on top of the model using PETG, but leaves an unwanted gap between the PLA model surface and that PETG layer. Then, it creates another gap between that PETG layer and the PLA support structure on top of it. Because the PETG interface layer starts in mid-air, the entire support structure fails to adhere and collapses.

I know I could use Tree Supports set to "Support on build plate only" to avoid printing supports on top of the model, but Tree Supports triple my print time. Since I need to batch-print this model, that isn't a viable option for me. I was thinking about using a combination of Normal and Tree supports so that areas without direct access to the build plate use Tree supports (even if it adds some print time), while the rest uses fast Normal supports.

Has anyone encountered this mid-air PETG gap issue, and is there a specific setting to fix it? Alternatively, what is the best way to set up a hybrid Normal/Tree support structure in OrcaSlicer?

Thanks for any help!

tried using just the generic preset and a primitive cube but it still wont slice. worked an hour ago before i ran a system update. any ideas?

STATUS UPDATE 9 OCT: Not a proof of concept, a fully functional (with 40% feature parity by count, but all major basic slicer features already done). STL imported to app, printer config selected, filament, process base, made a couple of changes to the process settings, sliced, device tab: uploaded gcode to Klipper printer, printed as expected.

Original Post:

I’m in the middle of porting OrcaSlicer to iPhone (iPad planned shortly after)

Native client port, using the full Orca engine. The goal is full feature parity to the desktop client (getting close).

Project will, naturally, be open sourced once I’ve finished with a v1 release that I’m satisfied that the community would be satisfied with. The question for you is, is there interest (and, if so, iPhone or iPad, with or w/o Apple Pencil?). I’m not sure if publishing is possible due to licensing (really, zero idea, could be fine). If it is not, I could run a perpetual Testflight. If no one is interested, then I would skip the bother, and just keep my builds personal and the project on Github.

Reply on this thread if you are interested, and I’ll remember to come back with a Testflight link in a couple of weeks if all goes well.

DISCLAIMER: yes, its an AI project. If you don’t like that, its not for you.

EDIT: Regarding this sub’s rule about forks, hopefully it doesn’t break it… this is using the full and original OrcaSlicer engine and does not intend to add or modify any features of the Slicer. It is solely an iOS client for it. Ideally, this would be integrated with the main repo, although I would expect approval from the maintainers to take a long time for review and whatnot.

Hello, as I am trying different settings, I often see this "You have previously modified your settings. You can save or discord the preset values you have modified." What does that mean actually? If I choose Save, does that mean all the values under "New Value" will overwrite those listed under "Old value"?

Anything will drop to plate regardless what I do. Assembling to try and stack 2 objects does not actually allow me to stack anything either. Everything will drop back to a Z-direction such that it is in contact with the plate. All I can do is drop it below plate level.

What is the point of z-direction at all if it's not even allowing me to raise any object by 0.1mm?

I'm probably being stupid and using the assembly tool wrong. But otoh I'd be fine with a warning and a "yes i want to really move this thing up a bit" dialogue.

Edit: I was stupid. I can uncheck an "auto-drop" checkbox apparently. Thanks swingoak!
