Do you get Maxtemp or Mintemp? Or something else? Usually mintemp or maxtemp is a loose, broken, or intermittent wire (moving the head around can usually duplicate the problem). But there is some other error that occurrs if the head doesn't heat up as fast as expected.
The head has enough power to melt the brown plastic part made out of PEEK. So if the readings are off by say 50C you can destroy that part and make a mess. If you are getting mintemp/maxtemp then it's probably wiring and I would change over to the spare cable (at both ends of the cable of course - both at the head and underneath at the PCB).
If it's the other error I would test that the head doesn't boil water at 95C and that it *does* at 105C and if that works I would keep my eye on the temp to see if it is bouncing around a lot and if it looks fine then I wouldn't worry too much -- well maybe I would time how long it takes to heat up and ask other people how long it takes for them. You might just have a bad heater wire that means it takes a little longer than normal to heat up. Also it would mean some of the heat is ending up at the point of higher resistance and you may be burning the connector where the heater hooks up.

In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
