### How to home KAP and KTH:
- Start PI software and make sure that servos are on
- #Note that if an axis will not move, check soft limits
- First zero KAP (417005588) stage. Starting from a position where the sample is facing up, the limit is located around -44
- To zero, open expanded view axis window and click on home with negative limit. When it reaches the limit, it will set the value to zero
- Before homing KTH (417005589), move KAP to 44 which will move the sample back to facing vertical.
- #Note: Watch the cooling braid during homing
- Open expanded axis view window and reference using negative limit. Is located around outboard 10CF window (ie KTH ~ -40). At limit it will set KTH motor to 0.
