2 Jobs tested and in production :) 2nd one much less stress ;)

2010 screen-set, tool change routine...

On this job I did exactly the same as before but the first cutter seems to have run about 0.2mm lower than it should, made a bit more mess out of my bed but i'm not worried about that as it's buggered anyway ;)

The next two tool changes worked perfectly and did not gouge the bed.

Anything that can cause this?

I have verified the code and all parts are cut to the same depth.
