Hello @ll, I just added a "E3D Titan Aero" kit to my Acrylic Prusa I3 Bro B - it looks fine so far... After all the needed changes the first prints showed a problem with the extrusion and after a few investigations the situation is as follows... The new hotend uses a 104GT-2 termistor. I saw it and changed it in the Marlin firmware as documented in configuration.h (5). If I measure the temperature now in parallel externaly i have an about 20% lower temperature as shown on the display (or in software). I already searched around a lot but found nothing... has someone of you an idea? Nice greetings, Martin
Hello everybody, I took some measurements and here is the result. My multimeter will not be 100% correct, but I think you can already see that we have deviations of 7-8% in the upper ranges that are relevant. From my point of view this is way too much, or do I see it wrong?
Hi @ll, Problem solved - the 104GT-2 is broken! I installed a spare sensor, performed the measurement series again and as you can see in the picture everything is fine now. The always exact deviations of about 3 degrees Celsius are either due to a blurring of the sensor or to the inaccuracy of my multimeter but in this case it is irrelevant as 3 degrees are perfectly sufficient in my opinion. So, I didn't find any support here for my problem, but I solved the issue myself and thats cool. Maybe this post helps someone else who has a similar problem.
