Fanuc 11M O return procedure?

Any of you may be able to give me standard procedures for zero returning my mill.

Thank you

Turn rotary switch to ZRN. If close to end of travels press - buttons for each axis. axis will move about 2" from end of travel then return a little bit. Then hold down + for each axis until the home lights light up.

Thank you, will give that a try. Currently mine just runs into limit switches and stops and i have to play with it to get it back off them.

Worked...Thank you

I had a machine with a 10m that didn't like zeroing when an axis was within about 3" from its 0

Zero Return behavior is determined by the machine builder, not so much by Fanuc.

Some builders do not allow the - direction buttons to function when in the ZRN mode. Some builders "latch" the + button so it does not have to be held during the ZRN operation. Some builders allow only one axis at a time to be referenced while others allow multiple axes to reference simultaneously or a mix of both. for example, on a machining center, Z can only be referenced by itself, but X and Y can be done together. Some builders have an "auto ZRN" function. Just put the machine in ZRN mode and press cycle start.

For machines equipped with incremental encoders, the distance that the machine travels or needs to be away from the reference position depends on the length of the dog for the reference limit switch or sensor, but it will always be more than, at minimum, one pitch of the screw.
