Homing for Absolute Encoders
« on: November 12, 2023, 06:03:38 AM »
Hi

Following this thread, https://www.machsupport.com/forum/index.php?topic=47822.0

I wonder what is the procedure when you have absolute encoders for homing operation.

At the moment we do not home the machine as the absolute encoders remove the need for a physical limit switch.
In fact, the Origin is set as an offset. Whenever we need to go to "home", we put G53 x0 y0 z0, and it goes to place.

We have tried to "home in place" when the machine is in its origin, but it tries to move and makes a bad noise.

Just wondering if our approach is wrong. Maybe I am overthinking it.

kind regards

Pablo
