@lasertechs the Messy workshop was uncomfortably full of smoke this evening.
@StudioNelle used it yesterday and it was fine.
I think it needs to be put it out of action – you don’t want to be breathing smoke. Could have been atmospheric conditions blowing smoke back in? As when I first looked outside there was no smoke coming from the vent, then later there was: so not a blockage. Possibly a leak?
@lewisss you have experience of the extraction system, @joeatkin2, you built most of it?
