I am struggling. I want to make sure I get this right. first time investment casting.

I need it to go to 300F hold for an hour. then raise to 700f hold for 1.5 hours. then raise to 1350f hold for 2 hours.  then drop to 900f and hold for 2 hours. then shut off

C01=90 T01=1
Co2=300 To2=60
C03=300 T03=1
C04=700 T04=90
C05=700 T05=1
C06=1350 T06=120
C07=1350 T07=1
C08=900 T08=120
C09=900 T09=1

You put all the ramp up or ramp down timers to be 1 minute. I'm not sure if your heater is powerful enough to reach the target temperature within one minute. You may need to process a test run and adjust those timers accordingly. By default settings, the timer will not be paused if your reading temperature is still far behind your set temperature. If you want the timer to be paused, you can use safety start feature. You can find the description on its manual. If you are using safety start feature, you can put all the ramp up/down timers to be 1 minute.

Also, please put -121 as the timer for the last step.

Here is your example:

C01=90 T01=1 // T01 is the time to ramp up from your ambient to 300.
C02=300 T02=60
C03=300 T03=1 //T03 is the time to ramp up from 300 to 700
C04=700 T04=90
C05=700 T05=1 //T05 is the time to ramp up from 700 to 1350
C06=1350 T06=120
C07=1350 T07=1 //T05 is the time to ramp up from 700 to 1350
C08=900 T08=120
C09=900 T09= -121
