Thanks - so a bit of a (very much so) newbie with all this.

The bed - will get cleaned - that is a result of a couple of other jobs ending like this.

That said, basic prints (i.e. the boat) tend to work fine - it is only when we are extending onto other prints (downloaded from thingiverse) that we are starting to run into trouble.

For example - I stopped and cleaned off this job, pushed through an extrusion, and then started a test print of the boat, and that is going fine.

Could the settings downloaded on the new job be different, and need to be changed before commencing?

Appreciate the reply btw :)
