Hi Makers, I did some mesurements today concerning the nozzle temperatures. I took a high temperature mesurment device (-50 - 1300 °C) and put it into boiling water and guess, it shows - exactly 100,0°C. I placed it very near to the nozzle under the silicone wrapping with some termalpaste. Then …

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 aroun…

Your right, these are no excat mesurments. But the original thermistor is not nearer to the nozzle as mine was, and sure there where differences but I never thought that there will be 40° difference. Can you tell me where the temperature must be on point if not on the heatblock? At least after a ho…

[image] stefix: But the original thermistor is not nearer to the nozzle as mine was But it is embedded inside the part. Yours is “only” touching it and on a different location. So there is a real chance that the actual temperature is different. It only has to be a few mm further away from the…

Will try to put the probe in the hole of the heatblock together with the original sensor. Lets see I will post the data when I have it. And metal pots are typicaly designd to do not transfer to much heat to their handels.

[image] stefix: Will try to put the probe in the hole of the heatblock together with the original sensor If you’re pulling the original one out, you could also just dip it in a glass of hot water together with the other one and see if the gap is smaller than you expect. (if you’'re water is …

There is definitley a temparature discrepancy… see my thread. I was printing with Silk PLA which is very temparature sensitive in terms of keeping its silky finish. On all my other 8 duet wifi based properly calibrated printers the material loses its glossy silk finish if printed at much more tha…

@stefix out of interest have you secured your thermisor with thermal paste or similar. As I wonder when snapmaker team first calibrated the tables… if they did it with a loose thermistor in the heater block… i.e. as supplied from factory then it wouldnt get as much heat transferred to it as it doe…

@chazr33gtr Will have a look to that, but not sure I have one thats not prepared with termalpaste

@stefix Have you seen Calibrate Hot End Thermistor? The numbers there seem roughly similar… Anyway could you send me the table in a processable format, I want to do some curve fitting?
