Thanks for the information - I will have a look into these. We were thinking the same thing about the max temperature for the cutoff, that it should be the desired heated bed temperature (for example 150C) plus 20 - 40 degrees -as you say, it is a safety measure and we sure hope it won't be triggered every day!
