I have just fitted my heated bed and heated it up for the first time.
I was pleased that the temperature increased pretty quickly and got to 50 degrees within a matter of minutes.. But when I felt the bed, it was luke warm at best, but underneath the heater was too hot to touch
I left it for 10 mins and the bed got pretty hot, but clearly the thermistor is affected by the temperature of the heater, rather than the bed.. And to be honest, this isn't really a surprise based on the design, as the thermistor is just sandwiched between the bed and heater, so its got to work like this.
Has anyone come up with a way to make it more accurate?
