This isn’t about a bug but a question about how it works, and I certainly won’t file a ticket as long as I’m going in circles with support regarding the MCU issues!
A group of software engineers just joined this week. I think the product manager’s focus will shift back to the slicing software. If you have any complaints or experience issues with the slicing software, you can post them here directly or submit a support ticket requesting optimization, and I will help relay your concerns.
My understanding of the scenario you described is: when you import an existing 3MF file, for example one downloaded from Makerworld, into the Snapmaker Orca software for slicing, are you confused about how to configure your colors and print head? If you could describe your specific confusion in detail, for example with screenshots or videos as references, it would help me better understand your scenario, and then I can convey it to the software team and urge them to optimize this workflow.
