Quick question about probing.

[boyd.sofield]

The last time I tried this inside a Fusion program. Something went horribly wrong, and my probe shot through my part so badly that it bent and I actually disassembled it to see if there was damage. That was about 4 months ago.

If someone wouldn't mind correcting me if I am incorrect and I have one other question: Mach 3 and I have a post that was made for probing by someone online - with thanks.

Ok so I plan to perform a second op on a part that needs to be exact for the second op (holes and a contour). This is flipping a part, and facing it on G54 approximate WCS because I am facing a larger part than the model. The Z will be precise though measured on the bottom of my part.

Then, I am calling for a probe WCS the X and Y. I have setup for a tool-change, insert my probe. Run the probing routine. I guess it will go to the current zero on X and Y, at the clearance height. Drop down, and probe the two faces I have selected. I don't have "override WCS checked" because underneath it has "WCS to be updated.... 1" written underneath.

Now, is this operation supposed to now update my G54 WCS in Mach 3 to the new coordinates the probe would have found? All automatic yes? Then will the machine ask for the next tool, and the next op begins just like that. All correct? I used to put in a manual stop, probe, continue the program.

The other question is, what does "Override Driving WCS" checkbox do?

Hope my probe doesn't crash again...... really I do.

Hi @boyd.sofield,

Sorry to hear you have had issues in the past.

In theory, Yes, exactly the process you describe is what should happen. However its all down to how its been implemented in the post and sub programs. 

Can you attach the NC code that your post will produce this might help in me doing a quick sanity check. 

Also for Override Driving WCS here is a video I made on it.

Hi. Oh we have to have these crashes once or twice - its how we learn lol.

Hey I just tried to post this program and it errored with something I have not seen before I have absolutely no idea how to fix this?
