Offseting TWP (G68.2)

[Ebannaw]

Is there a way to offset "Z", away from work in order to dry run new programs while G68.2 (TWP) is active?

I am new to this function and I am used to working with g54.2.

Really depends on the machine and the way your kinematics are laid out before I can say yes or no. Could you cheat by adding length to your tools? I would worry again on what kind of machine and how are the kinematics of the machine. Really need tons more information before I would say what is the best way to help you out.

With G68.2, the Z axis of the TWP should be the approach/retract. So you should be able to add/subtract your tool length offset. Just add your "offset" to the TLO, and then set back to actual when you are ready to run.

Thanks Gents,

There are over 130 tools in this program, so I used your offset suggestion with a twist.

I wrote a MACRO to handle the tool length adjustment then return to original number at end of tool use when wishing to dry run.

Thanks again for speedy replies
