M code for thermistor type?

[pmazz850]

I upgraded to an e3d and need to change the thermistor type in the firmware. Having trouble figuring out how to do that. I know I have to edit the configuration.h file but after that I don't know what to do. I guess I don't really know how to upload the change. Will this also rest or all my previous settings I'Ve made?
Is there an m code to update the thermistor type? I read it some where but don't know if it works with repetier firmware.
Any help is appreciated...

You'll need to change thermistor type and the max temp from 240 to 300. Check out the seemecnc channel on youtube. Oly walks you through the firmware process.

Afterward, you'll need to reset you PID values for the hotend. You can do that in the eeprom. Setting up the PID is in the manual. Follow the instructions. Only takes a few minutes.

My main concern is this, if I load the firmware up in the arduino ice and make the change to the configuration file, and upload it, will all my settings revert back to initial settings? Essentially starting over?

If you don't save your eeprpm config files from repetetier. If you open eeprom config in retier, at the bottom are two buttons, one to export the settings, and one to save.

So I want to export and save the settings, edit and upload configuration file(firmware) then import my saved settings?

Yep.

Ok , so I did as stated above and after went to run the autotune pid and the hot end heated up, and then the autotune failed after some time. Now hot end won't heat up. It is showing temp readings on LCD so I think thermistors are ok. Could my heater cartridge have burned out??

Ya I burned out a heater cartridge. I mistakenly changed ext pid max to 300 instead of max temp . New heater cartridge and it back to normal. Now to try out my new e3d. Thanks for the help.
