No need for mulitple posts, as Easel / Easel Pro is not different here.
1 - During homing the machine reference is synced to your design enviroment. It doesnt matter what the machine coordinates show, positive or negative value.
2 - Easel / Easel Pro user interface do not have a homing button. You need to issue a $H comand in the Machine Inspector Console window.
Typical work flow:
- Power machine ON
- Do a homing cycle ($H, establishing a machine/model enviroment reference)
- Fasten your work piece and jog your bit over to your intended work zero position (stored as an offset from machine reference)
- In Easel, to set work zero, click Confirm Home Position during the setup process
Home position do NOT equal homing position (switches) - Carve
