New Release FluidNC v4.0.4 2026-08-05

Has anyone attempted to install the latest version?

Is it safe to start updating JP3?

Regards

I don’t see any reason to change to it yet. Best to stick with the know good versions for now.

4.0.3 is working fine for me. But 4.0.4 has a major telnet bug which won’t allow MillMage to control it. But as Ryan said, there isn’t any compelling reason to update.

How’s the remote file upload work with 4x? I’m tempted to update so I don’t have to sneakernet SD cards the full length of our property every time I need to change a file.

That v4.0.4 version probably should have been a v4.1.0 version. They made significant changes to allow it to work on other hardware. I wouldn’t go past v4.0.3 until later versions get more thoroughly tested.

It works great for me.

I successfully updated the version to 4.0.4..

Hmmm

How do you save any changes to if there is no save /write button?

That was fixed but not sure what version. Try the latest 3.0.10 version here. Just replace your index.html.gz file.

I did too, then realized there was a telnet bug and couldn’t use MillMage to control the LR4.

Is the same version - I have installed.
