Question on lathe & post

[rdshear]

In the toolpath parameter pages, there is a box for the "Home Position". The pull down gives the option of from machine, user defined, or from tool. My question is where does mastercam get the X/Z coordinates for the "From Machine". I have looked in the machine def, control def, and in the post. I cannot seem to find a reference to it anywhere. The numbers always seem to be X5, Z10. Can I change these?

 

Also, is there any way to determine in the post which option is selected so a different output can be obtained?

 

I need to place an M91 in the NC file line when using the machine option so my control will go to a reference value instead of an actual number based on the WCS. Of course this only makes a difference if I can change the machine default.

 

Thanks,

 

Rick

I'm not sure either , but I want to get rid of that home position move completly at the beginning of my program, and the g98 in my lathe post . don't need it ...can anyone help?

You might try playing with the misc. integers. In the post I'm working on, there are 4 options for the 1'st misc integer. -1,0,1,and 2. Each one changes how the home position is placed in the final NC file.

home postion is on the first page of the edit machine definition manager. At the top it is the second icon from the far right..little blue red and green arrows...called axis combinations.

If it was a snake it would have bit me.
