[BUG] Polling command does not check response

[sstefanov]

Describe the bug

I have Anet A8 printer with added ESP3D. Added is filament sensor. Marlin is updated to 2.0.4 with filament sensor support.

I set polling every 5 seconds with M105 command to display temperatures. The problem appears when printer is paused for filament change. After change and resuming print, there is message "Click to resume ...". I found this is due to buffer overflow caused by M105 command.
https://3dprinting.stackexchange.com/questions/7217/what-triggers-marlins-click-to-resume

Seems that ESP3D does not check command response and blindly send next commands. This produce buffer overflow in printer controller.

To Reproduce

1. Start printing
2. Click pause printing or remove filament to start Change filament procedure
3. Wait couple of minutes
4. Resume print

Expected behavior

After resume print this message should not be seen and print should resume without additional operator input.

buffer overflow from who ? Marlin ? => Marlin Issue, it should handle
And no, polling command do not wait for response, this is by design

if you want workaround set Marlin to do Auto repport for temperature and disable polling command in WebUI
