Orca Slicer cannot open "Exported Sliced File"

[NikosSprocket]

I want to save a "project" that includes filament changes at specific layers applied at the "Preview/Slicing" step.

Saving a project does not save the sliced information, as I had used to do with PruseSlicer and SuperSlicer.

So I tried the "Export Plate Sliced File" function, but Orca cannot open this file and gives an error "No Geometry"!!!!

Any thoughts/solution on the above?

You probably just have to run the slice in Orca and insert he pauses again. If it were me doing this, I would have both slicers open so I can refer to the old project to know which layer to move to.

I have already created the "PAUSE" commands for the layers where I need to make the filament changes and I can generate the Gcode to print it; as I have done already.

The problem is how to save with Orca the information for PAUSE at the same layers, so I can "Open" the 3mf file, slice it with the existing PAUSE locations and print without having to re-create the PAUSE points. 

If I just save it as a Project it looses all the PAUSE information. With PRUSASlicer and SuperSlicer the PAUSE infromation are saved to the "Project" file 3mf format.

Strange. I just did a quick test and "Export Sliced File" works for me with the pauses.

I have noticed that if I use "open project" it imports correctly with pauses, but if I "Import" the 3mf file it shows the error of no geometric data

Thank you!

Is it "Export Plate Sliced File" or just "Export Sliced File"?

I will try it.

No worries,  I will try to open it with Project option.

Thanks guys! Very valuable info.

@mvdveer It does not work yet. The interesting part is the same 3mf file from the "Export plate sliced file" operation could not be opened by PRUSAslicer 2.9.2 either. I think I hit another ORCA bug ...... Still "we" pushing PRUSASlicer team to bring back a future that is removed two versions ago, Toolhead clearance area is not shown anymore when moving objects on bed #14240 so ORCA it is for now.....

Unfortunately, I am not a software developer and cannot do anything about these .... annoyances

There is a new alpha version released which is what I used.

Here is your project file that I opened:

I got the alert from Orca last time I launched it. A couple of the new features are really interesting, but I figured I'd wait a week or so until it gets to beta.

Have you found any glaring issues with the alpha version?

Wow! Thank you!

I guess I will try  .... alpha. Hopefully will not explode my Voron (not lol).

From memory lane:

The old days there was an unspoken rule that all even numbered software releases had more bugs than odd versions.

Of course with AI all bugs are eliminated
