I crashed my probe the other day. I left a variable set for a part that was programmed for .750 exposed, yet i had a 1.375 part in there. Poor planning.... i usually rapid to ~1.5 above part, then m01 and eye up distance to go. g54 Part zero is usually top of part, this time g54 was programmed as g54fixture face z+ part length and then assigning z face offset to g129.

Should I insert the G31 code where i put !!!!!!!!!!!!!!!!!!!!!!!!!?
is there a code to take it out of this mode? Cleared at mo6?

Also since i am using one sub for tool postion and one for actual motion cmds, with an m01 to check variables. Should i restate g31 in the O00901 (PROBE PART) program, that moves the probe from rapid position to part for probing?

I use a generic tool approach subprogram to move within z1.5 of part face then my controlled f10. ipm moves are setup like this :

Just needed verification that g31 will stop the machine hits something with the probe.

G31 on haas vf-2 = feed untill skip fucntion.


Saw this on another post.....
"I don't understand that if you have the Renishaw 9000 macro's it should include a protected move routine, i.e. you should never move any axis with the probe in place without a G31 in the routine, which the protected move has.
If a rapid move to initial position is performed and a probe collision occurs, all axis will stop.
If Fadal have modified the probe routines, to my mind they should supply comprehensive documentation on usage.
Whats with the uncontrollable Rapids?
A Renishaw crash can be Very expensive.!"

Not relevant but if anyone can use it to learn parametric.
Here is the MATH SUB that is assigning vars based on the family of parts :

I think that was a reference to one of my posts, normally when the probe is mounted, you should never move it without a G31, the protected move is for any move that takes place other than a measuring cycle.
IOW, if you are rapiding to the measuring position, the G31 detects if a collision occurs and takes steps to prevent damage.
The G31 should stop feed on all axis immediately and fall through to the next line.

would the machine be able to respond fast enough during a rapid move?

While studying the renishaw macros, I always see G31 on a line with a F value for feedrate. I didn't even think it would work on a line with G0.

[Haas_Apps]

I would use a M78 followed by a fast g31 to try to avoid a crash.

PaintItBlue...

It looks like you are using the easyset or VQC (9023) macro for running in automatic mode... It obviously works but the intention was for it to me used for setup. To program in automatic mode it is much easier to use the Inspection Plus calls. Call Renishaw and they will email you an Inspection Plus Manual for Haas machines. The protected position macro is 9810... Here is a skeleton program I use and you can adapt it with the variables and settings you like to use....

Hope this helps.... but if you feel more comfortable using 9023 you should continue what you are doing.

Will give it a try, i am always willing to learn the right way so the wrong stuff doesn't appen again:P

you could write it like this:
the G31 only applies to the block its on
