I believe the firmware will stop extruding once the temperature hits 160 to prevent damage to the hotend. Since 170 is quite close to that, maybe it's briefly dipping below the cutoff temperature? This can be overridden by enabling "cold" extrusions with the M302 command, though that's usually only done during maintenance.

Is the measured temp actually dropping under 170? If so, do you have a part cooling fan that might be cooling the heating block?

How did you calculate the optimal temperature? Normally this is done by a test print.

Are you really certain that the relationship ship between the displayed and actual temperature is changing? That is not impossible if your Duet or thermistor is faulty, but is certainly unusual. Can you check using a multimeter with thermocouple probe? Are the thermistor leads secured so that the thermistor cannot move within the heater block?
