lathe home pos in x8

I tried putting a value in the boxes but it still outputs g28 xz 0.s it the post doing this?

im using the standard mplfan post.

Yes, the standard MPLFAN post will output a machine home move for the Tool Change. What are you trying to get for output? Do you want "G28" with a machine location? (G28 X-10. Z-10.)

 

The easy option (if your machine has it) is to use a "User Defined Reference Position", which defaults to "G30". To enable this output, just turn on Misc. Integer #3 in the toolpath dialog box.

 

That would give you "G30 X0. Z0.", which would correspond to the tool change position you set on the machine.

 

Anything else would require a post processor modification. There is a "Home Type" option, that is set with Misc. Integer #1, but this would also alter the output for your Work Offset output, which you probably don't want.

this is on a haas toolroom lathe. I rarely ever want it to go all the way home in z so I usually modify the code mc outputs to goo x 8. z 5. or something close to this.

I was hoping I could just create a point on my screen and click it when I define user defined home position.

I think g28 will send it all the way home regardless of if there is a value or not after it.

thanks,

ive never use the misc value page in lathe.ive used it for sub repeats in mill though.ill give the g30 a try.
