[BUG] Axis coordinates don't show in the control tab

[Liger0]

Describe the bug Axis coordinates often don't show in the control tab.

To Reproduce Steps to reproduce the behavior:

1. Activate the position check (I have it to 10 seconds)
2. It will show the coordinates and update 1 or 2 times
3. It will stop showing coordinates.
4. After this no matter what you do, it won't show coordinates again.

Expected behavior Keep showing coordinates instead of blanking them

Do you have screenshot?

It will show the coordinates and update 1 or 2 times

What did you do to change position?

After this no matter what you do, it won't show coordinates again

What did you do? How long ?

I don't have a screenshot now, I will do it later when I finish the long print I am doing. I can't do it now because always, mid print, the commands tab just keeps throwing echo:busy: processing multiple times and never connects to the printer again (same happens after a print is ended, it stops communicating and I have to restart the control box (the screen still shows the IP correctly).

I didn't change position. Just started a print. I just tried to enable and disable the checkbox of the coordinates showing (leaving a minute between any click), but with no result so far.

Print from sd ? Or from usb?

[Liger0]

SD

Busy: processing come from Marlin https://github.com/MarlinFirmware/Marlin/blob/9badd2b664463557d17449878b91ce84d5eec676/Marlin/src/core/language.h#L177 Seems it does not accept commands there nothing ep3d can do

[luc-github]

Any update?

[Liger0]

Nothing so far. I guess it should be closed?

[luc-github]

Ok as if Marlin does not allow any command when doing SD print - ESP3D cannot do anything Anyway Marlin has auto temperature report to follow temperatures, so no need to poll and it works with ESP3D- but I do not think it has same setting for position.
