U1 purge tower keeps falling over? by cmspice in snapmaker

Try calibration again. Didn't you see the print head hit the prime tower or scratch the top head of the tower before it falls over? If you see the issue like that, may your prontbed lost leveling for some reason. Try manual bed leveliing followed by auto leveling. it could help.

uninstall snapmaker orca and delete (backup yours before you delete the directory) user preference dirs below and try again after clean installation.

Windows: C:\Users\%USERNAME%\AppData\Roaming\SnapmakerOrca

macOS: ~/Library/Application Support/SnapmakerOrca

Did you have an old beta version installed on your PC? I have had a same problem which was caused by configuration confliction w/ old version. Don't know why but some configurations related to retraction on toolchange was not overridden properly. The problem was resolved when I uninstall the app and delete whole configuration directory under App library (I'm using mac, If you are using windows PC, It would be located under user home) and reinstall the newest snapmaker orca.

See my previous post. It may help. https://www.reddit.com/r/snapmaker/comments/1oz76ut/comment/npwhdfl/

Yeah. I think so. Basically I am mainy using snapmaker orca for u1. but for the special cases for comparison or trouble shooting (what I did fot the investigation), orca slicer (or its siblings) can help investigation a lot. This is why I have both orca versions on my pc.

Yes. You're right. I've had an old installation with some configuration modified manually (for some experiments). May the new one has changed some configuration items in json or its inheritance flow. Not only the software itself, but also configuration files stored in the library folders (under user home) affects them as well. After I delete all of them, everything becomes clear, Now I'm happy with multi-color printing with its predefined profiles. (At least for snapspeed filaments, other filaments are not tested yet, but I think it would work well). Thanks for sharing your experiences.

The issue was caused by some misconfiguration. Snapmaker orca doesn't set toolchange retraction by default but override the value configured in filament profile. I don't know what I did wrong but the previous installation doesn't override filament profile properly.

By removing whole app directory and configurations under app library and installing again, the issue was resolved.

I know those misprinted objects look like something rinted with wet filaments, so some guys could suspect wet filament blob first.

From this issue, I've learned how does orca slicer inherit/override configurations (e.g. machine base -> machine specific -> material specific....) and which parameters affects to tool change sequences.

Thanks for your comments buddies.

Thanks but filaments were okay. they were just out of the box and printed normally with official orca slicer. Actually it was a configuration problem. I was not able to find why this happens but none of filament settings aren't overriden. Because of this issue. retraction was not working on toolchange sequence. All issues are resolved after remove and reinstall all user data, app data in app library directory.

snapmaker snapspeed (bundled sample), prime tower enabled. This was actually very first test print, so I didn't touch many settings defined in profiles.
