Ultimaker reading consistently ~20°C temperatue off

· Ultimaker reading consistently ~20°C temperatue off
This is definitely useful info, Sander. In the past I've measured my hot end temperature by using kapton tape to attach an external thermometer's thermocouple probe to the side of the aluminium block, adjacent to the nozzle, and then also wrapping some insulation around it.
I found I got temperatures that were very consistently 5% below the temperature the UM was reporting, across the entire 180-260 working range I tested. I'm not sure if this is explainable solely in terms of thermal gradient from the inside to the outside of the block, or whether one or other measurement is really off by 5%. Based on my tests printing some plastics with fairly narrow working temperature ranges, I suspect that my printer may indeed be reading 5% - roughly 10-15 degrees - too high.
Has anyone else compared external/internal block temperatures and can give me a sense of whether a 5% difference seems legitimate?

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
