Nozzle Tempeatures

I think you shouldn’t underestimate the potential temperature difference based on the location of the sensor. It’s probably not easily feasible, but if you would swap the locations of the thermistor and your measuring probe, you could validate if you see a similar delta, or just the other way around. Or if you dip the SM thermistor in the same pot of boiling water as your measurement device, do you still see that delta?

thats the post… yeah i hoped like with Duet Wifi boards could just run an auto Proportional Integrational Differential (PID) tune… but no they have the thermisor values hardcoded in a table. When i get chance I’ll recompile the firmware with a modified thermistor table… when i get chance!!
