at what temperature does it start to become a problem with cutting. I have some pieces at the end of a run that are barely touched. my temp gauge is at 28c
I read some tube tech spec -> temp range is 15-35°C
well im welll with in that then. just testing it again in the problem area and now its cuttng like butter. strange
realised what it was. one of the elements were copied from a previous file and I didnt realise it has placed it on a differne layer with different settings. all is well now
SO it was a keyboard --> chair interface error? 
Indeed
