The thermistors are "interchangeable" only in 0-150C interval. After that point, each thermistor has its own mind, even from same lot. If you really want accuracy you have to calibrate the thermistor with a thermocouple attached to the hotend, and change the values in firmware table in the temperature column. You issue a command to heat up to a temperature in the table row, that heats up untill the adc comes to that value, then read the thermocouple value and next update use the real value for that place in that table row for that adc value. No way around this: you either calibrate your own thermistor table and you can say your 230C= real 230C, or you have to settle to "some" reading that represent "some" level that starts and stops the heating, and read values can very well be +/-20C or even more error from real temperatures.
Congrats for your print :)
Can we assume that its all working ok -or there are any other problems left?
