In process multiple work offsets

[marcmt88]

Hi.

I am trying to automate probing multiple pieces from G54 thru G56 before cutting each part with each tool. 

I am encountering Error Code 1086, Path Obstruction (Haas NGC) on line #N50.  It error out right before probe entering the first bore.  Please see code below.

Hi @marcmt88,

A path obstruction error means the probe has triggered when it should not have. 

There are 2 things this could be, an actual trigger of the probe because it has hit something. 
Or a false trigger caused by the machines movements and a sensitive probe. 

One way to find out is to run the positioning moves slowly reducing the acceleration and deceleration of the machine and hopefully eliminating any false triggers. 

Once you have established that the NC code will run we need to solve the false triggers. 
Things to check. Is everything tight, I have sen before loose probe bodys and loose sytli causing issues. 
I'm taking a guess you have a renishaw probe, these have built in filtering to stop this kind of thing and it has multiple settings. 
See section 4.1 on "Trigger logic" this can take a while to get the hang of how to do but it will allow you to set the inbuilt filtering higher.

Give those a go and let me know how you get on.
