Current height doesn't change

What is the problem?

Started a print this morning and for the first 4 layers, OctoPrint reported the current height as 0.3mm. It was only when it got to layer 5 did it change to showing the correct height.

What did you already try to solve it?

Refreshing the browser

Have you tried running in safe mode?

No

Did running in safe mode solve the problem?

Please do so.

Your Pi seems to get quite hot.

And please attach the systeminfo bundle to your next post.

The temperature of the Raspberry Pi is 51.0°C

Anyhow, the Pi reports Soft temperature limit has occurred

There are issues with Obico:

You are running Obico and OctoEverwhere side by side.
For functionality, only one is necessary.

And please avoid restarting the Pi by pulling the plug:

2023-02-25 16:47:45,557 - octoprint.plugins.obico - WARNING - Server WS ERROR: Not connected to websocket server after 5s
2023-02-25 16:47:48,310 - octoprint.startup - INFO - ******************************************************************************

2023-02-25 16:47:48,317 - octoprint.startup - INFO - ******************************************************************************

This can lead to corrupted a file structure on the SD card in the Pi.

I haven't unplugged the Pi:
pi@octopi:~ $ uptime
10:04:50 up 24 days, 2:15, 1 user, load average: 0.38, 0.30, 0.34

This might've been when one of the plug-ins had an update yesterday.
