Assuming you were raster engraving, what speed were y'all running at?
Try reducing your speed and power proportionally to reduce this kind
of error.

Also note there is a wealth of information about this 40W laser
engraver on Full Spectrum Engineering's forums:

Nota  Bene:
Please consider contributing to Noisebridge if you are a frequent
Laser user. You can do this in a number of ways, by monetary donation
or by creating something with your engraver time or other skills that
can be used at Noisebridge.
It's a lovely resource and quite a feat for it to remain fully
operational after 1.5 years.   It will not be cheap to replace 'the
Tube' when it comes time to do so.
