Yasnac I80 groove finding help.

[K Battenbough]

Trying to use the groove feature on yasnac I80 and can't figure out where I am going wrong? I am getting to point 1, pressing WRITE, getting to point 2 pressing WRITE, and then a huge random number populates the offset? Am I doing it wrong? tried it in both inc/abso with the same results. Any pointers would be great.
Thanks

I been through this. It is when end move is not in the opposite direction. It not only takes position but also axis drive direction before write. So you dont back drive axis before writing. So if you overshoot, you drive back, and go forward again for 1 click.

So I get to one side of the groove press write, jog to opposite side of groove then write, is that correct?

Yes. As well as outer side of the part. Center of rectangular stock works as well. Machine does not care that X+ and X-(or Y+ and Y- as well) are reversed

Tried it today and it worked great!!.. I have a habit of deliberately going past zero by .2 say and then go back to zero on the haimer on the the first reference to take out any possible backlash, but did it like your way earlier and it works perfect!. Many thanks.

Ballscrew machine with backlash comp does not need that.
