Hello,
I am working on a UR5e with SW 5.13.1.
I tried to change the first tool ~~actual “Tool Flange”~~ properties under the Safety “Tool position” settings.
I logged in with safety password.
From the first tool (the one where I want to change an value) the properties are **read-only.**
I am able to add a second and third tool and change the properties (and delete the tool afterwards).
The first tool I could also not delete.
Best regards
Jan

Hello Jan,
You’ve never been able to change the tool flange settings. 🙂
The flange will always be a safety “point”.

Thanks for the reply.
But I had already changed the “first” tool some time ago (also some SW versions before). I set a position to X 0 Y0 Z 80mm and a radius of 50mm. Now I want to change one of the values.
Sorry, it’s the first tool (in the “English” documentation it was called “tool flange”, could be a custom name).

Hm, that sounds weird. Well. I might be wrong, but I don’t remember it ever being editable.
You can clear it by making a new installation. 🙂

Here the screenshot of my settings.
I think I have to do a complete new installation of my robot ☹

A complete new installation? As a new PolyScope? I don’t think that’s necessary. 🙂
Have you tried making a new Installation? Go to New (Neu) → Installation.

No, just a new “installation” file, not complete setup. This worked.
Thanks for support.
