Replicator 2x nozzle calibration temperatures

I have print settings dialed in pretty good and getting reliable bed adhesion. I can get dual nozzle prints to build and are starting to look good.

It seems my nozzle calibration is a bit off resulting in a shift in x.

I want to run my nozzle calibration script to correct this, however, I want to run this script at my preheat settings rather than the fixed settings in the script, which seem to be set for abs.

these hard coded settings will not work for me.

Does anyone know how I can change the temp settings for the nozzle calibration script? I could edit the .gcode if I knew where it lived...

thanks for any advice.
