Re: [CAD_CAM_EDM_DRO] Home Switch Setup

Hi,

The setup would be:
1. The limit switch position is NO ( normally open). When it hit home
position/overtravel, the swithces closed.
2. The Bit transition: High to Low.
3. The Limit switch active : High
4. My set up do not use any pull up resistor. One goes to the pin, one goes
to the ground.

Hope it helps.

Fortino
