hi all  
Unboxed my new TAZ4 yesterday.  
Have an error message: MAXTEMP  
I measured both thermocouples. they are around 135K  
Checked the wiring connections, but the error message remains.  
Any advice would be welcome

Stripped the motherboard thermistor wiring and stuck a 100k resistor in them  
Traced the problem back to the nozzle and guess.

The nozzle motor and heater wires are interchangeable.( maybe a to be avoided design ?)  
My color recognition skills where nowhere to be found when i plugged them all together.  
End well all well. Cheers
