ValueError: height of box too small

I’m starting with a Draft:Shapestring to create an engraving path. Upon selecting the shapestring and creating a new job, I receive the following:

09:47:01  Traceback (most recent call last):

There doesn’t appear to be anything useful regarding “No module named ‘PathScripts.PostUtils’,” and no amount of messing with the size of the shapestring eliminates “height of box too small”, and it fails with both Vcarve and Engrave. I just want to engrave some text…

Thanks!

Thanks, but that did nothing of value.

Message “No module named 'PathScripts.PostUtils” comes from outdated estlcam_post.py. Sorry, I missed out this on first sight.
(I recommend turn off all unused postprocessors)
Could you provide a file?

The location of “PostUtils” changed during a code refactor.
With FreeCAD running you can locate the file , now called “Utils”. for my current version it is "/tmp/.mount_FreeCA1L8pXR/usr/Mod/Path/Path/Post/Utils.py "
the " .mount_FreeCA1L8pXR " part will vary according to your installation.

The post processor file is located in similar fashion ; " /tmp/.mount_FreeCA1L8pXR/usr/Mod/Path/Path/Post/scripts/estlcam_post.py "
Copy the post processor you want to use, paste into your Macro directory and edit so that the import for PostUtils comes from the new directory

You will have something like the first two lines in the following code example.
Comment out the PathUtils reference with # i.e., #from PathScripts import PathUtils
Comment out the PostUtils reference with # i.e., #from PathScripts import PostUtils
and paste line
import Path.Post.Utils as PostUtils
you may not need the first "Post. " seems to depend on the system.
You could also use import Path.Post.Utils as Utils in which case need to use the Find function in a text editor and search for “PostUtils” and change it to “Utils”

#from PathScripts import PostUtils
#from PathScripts import PathUtils

from PathScripts import PathUtils
import Path.Post.Utils as PostUtils

Experiment with the import path, it may require an alternate wording, but since you are using Debian one of these should work.
.

and no amount of messing with the size of the shapestring eliminates “height of box too small”, and it fails with both Vcarve and Engrave. I just want to engrave some text…

Have a look at this topic for this error
https://devtalk.freecad.org/t/creating-a-2d-path-job-for-shapestrings-fails/54797/1
The end result is that you need to give the stock a height

Thank you bmsaus4ax! That did the trick.
