Suddenly unable to select machine in setup

AtomicGumball — Thu, 18 Sep 2025 21:01:17 GMT

One of our machine definitions recently stopped working. When selecting it in the setup, we get "Cannot perform select operation on invalid machine asset!" as an error. To my knowledge, nothing has been changed in the definition to invalidate this machine.
What should I be looking into that might cause this issue? Is there a way to view version history on this machine?
I did not see the machine in the assets folder when I went looking for it.

The machine will only be in assets if its stored in the cloud I think

Can you export the machine and attach to a reply here?

We may be able to see what wrong with it

Here's the machine file export.
It shows up as a cloud machine when I go to select it, but I don't know why it's not alongside our other machines.

Hi @AtomicGumball .

Postprocessor currently supports only 2-3 primary linear axis for machining. You machine has W axis on a sub spindle, that is not currently supported for regular motions. It needs to be marked as "Supportive" to make machine valid for selecting in setup.

Why did it work previously then? Was there a change in the last update that would affect this?

Yes, sure. Previously Fusion checked only main spindle kinematic chain for validity. In the last update it started to check sub-spindle chain too. And because it has an issue, you now see this error.

I am curios, how do you use these machines? Do you have any post, that uses them, or you use them on Fusion side only? As I remember, we don't have any official turn-mill post, that can use machine definition from Fusion yet. Dual-spindle machines support is very basic now.

The post we pulled from the fusion library. I added the machine definition stuff to see what fusion was capable of, but found we couldn't do anything useful simulation wise. We mostly use the machine definition to communicate machine usage on repeat parts.
The post has been handling everything thing else, after a few edits and fixes from myself. We run simulation on the machine to check for collisions.

Hallo

Will there be better support for such machines in the coming years, e.g. with machine models and 3D turning tools?

Thanks

@Christoph_360 I'm 100% certain that machine models and 3d tooling is going to be a reality in the future, and I'm not talking "years away"..
