No, I have an Ender 3.
1. No, Ender 3. The XYZ has always been at the center for me, unless I'm losing my mind and never noticed it. Or I mixed it up with the XYZ for the actual object.
2. That's tough, 4 days a week I use it on Ubuntu 20.04, and 3 days a week I'm on Windows.
But I ended up unchecking it to test, and it's back to normal. Kind of misleading, especially if only Delta printers use it, why is it available on an Ender 3?
