Title: Tool Offsets being turned off
Post by: dec@rocketmail.com on May 01, 2013, 06:46:24 PM

Hi all,

I am trying to get my head wrapped around tool offsets (we just installed our first ATC). 

When I go to the Offsets screen and set the "Tool Offsets on/off" to "ON", I see the DRO display the correct Z value.  But when I start a toolpath, it goes back to the standard fixture coordinates.  I have added a Tool_Length_Offsets = YES line in my post processor, but no dice.

Any leads?

Does your g code issue a G49 during the initialization?

This turns off any current tool offsets.

Hi Paul,

Yes, in fact.  I removed it and added a "G43 H__" after every M6 command (where H matches the preceding T__).  Does this look right to you?

Your code appears to be correct to me, single step thru it to make sure.
