Thermometer purchase...?

[BestGear]

Guys - thanks for the replies and ideas!

My lead in to this was clicking extruders, so I questioned the temps.

The thermistors are K type and I ave ordered some new ones. My guess is that they are over reading the temperature... causing the restriction to feed.

I just wanted a thermometer so i can be really sure, and with Sailfish, understand there is no way to calibrate them unless I use washers between the thermistor and the heat block (which seems to do the trick!).

I had not thought of black paint - thats worth a shout... not sure with the Ir I would have a big enough "black" target though....


Will let you all know...
