I will have to look in the log file for the offsets. But the Axes are still where they were paused. I am not entirely clear how to open the log file but will attempt to poke around and look for it when I get home this evening.

Hey B.

you can open the log file /var/log/bbctrl.log with the usual text viewers installed on all unixoid systems like [less](https://en.wikipedia.org/wiki/Less_(Unix)) that has a search function that highlights matches like “offset”, or text editors, and of course you can search for strings with [grep](https://en.wikipedia.org/wiki/Grep). The text editor [nano](https://en.wikipedia.org/wiki/GNU_nano) is installed that also has a search function.

The axes moves that the g-code makes usually look this way:

```sh
I:Comm:> {"xp":20.987,"yp":10.052}

```

After you pressed pause on your g-code program:

```sh
I:Web:200 PUT /api/pause (192.168. ***.** )
I:Comm:> {"xp":21.124,"yp":10.06,"v":0,"xx":"HOLDING","xc":71,"pr":"User pause"}

```

In this example, 21.124 and 10.06 are the X and Y positions after the program was paused.

Regarding the offsets, the last XYZ probing or G92 occurrence usually looks this way (these are the offsets in the offsets column then):

```sh
I:Planner:set(#58, offset_x, -15.0)
I:Planner:set(#59, offset_y, -20.0)
I:Planner:set(#60, offset_z, 15.0)

```

Note that /var/log/bbctrl.log is subject to [logfile rotation](https://en.wikipedia.org/wiki/Log_rotation). Should the file be empty, you find the older log under bbctrl.log.1.gz (view with zcat, uncompress with gunzip)
