Amen.

It is showing default for a second extruder except for the current, that's the point I'm making. But, when I see something change with it i.e. the current, it would lead me to believe there is a bug or something that needs cleaned up.

So for me, I don't have a U, but drive 4's current matches drive 2s current as it should as it is mapped Z2:4, but none of the other values do corresponding to that drive. I would expect drive 4 to be a mirror image of drive 2.

It is if you really follow it, in my example, it maps the drive current to that field. just nothing else. My Z axis is 2:4, so if it is truly just axis based, then the current shouldn't update, if it is drive number it should match, but it shouldn't be a combination of both. Maybe the web control should be updated to only include configured Axis.

0 No 0 mm 224 mm 15 mm/s 100 mm/s 1500 mm/s² 1200 mA
1 No -22 mm 202 mm 15 mm/s 100 mm/s 1500 mm/s² 1200 mA
2 No 0 mm 180 mm 1.67 mm/s 20 mm/s 300 mm/s² 450 mA
3 Yes n/a n/a 110 mm/s 36.67 mm/s 600 mm/s² 1350 mA
4 Yes n/a n/a 2 mm/s 20 mm/s 250 mm/s² 450 mA

This was the same thing I reported. the acceleration settings or other bits don't show up correctly.

I am using 1.20. David, 2:4 are my axis. It displays the current correctly, just nothing else. I don’t use the info for anything, just figure it would pull setting for what was mapped for those drive positions.

Was worth a shot, but a no go.

it certainly was unexpected! Now, what about the settings tab issue?

No, it was all removed after I learned about E3. I've posted the entire config below sans wifi setup

I mean the other properties of the same axis should match i.e. accelerations, speeds, current is about the only thing that matches.
