still awaiting it in college tomoz but gonna nip down to rep shop and see if they can help me. get one form there [no charge] and then give them this one that i ordered.
I always struggled to keep the hot end up to temperature until I read a few things on here and took some advice and realised I had way too much substrate over the mat and was stopping the heat coming through. You could put more substrate over the mat until your stat arrives, although it would be simpler to turn the mat off if its only for a short time.
