Did this ever get figured out? It has been awhile since I have been on this thread. I also have not been able to play much but I did decide to try a part today and the same trouble. Todd's response works fine but I was hoping to use my now old toy.

Not by me. It kept crashing on the side of the dime no matter what I tried until I just gave up. The other posters may have had better results.

Hey guys,
A different Joe here with the same or very similar problem, When I try to use smartprobe.ngc, it starts probing fine but inevitably, I get a "probe is already tripped" error. It mostly occurs in the same place but sometimes it'll go for a while before it throws the error.

I found a reply from a while back where someone suggested adding "debounce" to the HAL file but I can't figure out how and I'm not sure that will help my problem.

Forgive my ignorance but would it help to modify smartprobe.ngc to raise the Z another fraction after the probe loses contact with the object? If so, how?

I can use gridprobe.ngc but it is painfully slow, I'm just looking for a better way.

Any help is appreciated,

Thanks
Joe

I found the answers I was looking for and am adding it here to help others that may also have this problem.
I found that someone had already solved this problem by modifying smartprobe.ngc to Probe-on-Steroids.ngc but I kept getting a different error when running it. I simply copied 2 lines from Probe-on-Steroids.ngc and pasted into smartprobe.ngc and it worked great!
Copy the following

G91 G01 Z0.2 (Lines added to the SmartProbe.ngc)
G90 (Lines added to the SmartProbe.ngc)

paste these between lines G38.5 Z#7
and
G38.3 X#11
Change the Z.02 to indicate the added distance you wish Z to travel after the probe loses contact.

I hope this helps
Joe

I just added the two lines and am running it right now. It does seem to be working. My machine is homemade and real slow but it has not failed yet. I really need to learn G code so I can do more. A perfect find by you. If this works out I will be ready for Christmas this year. More understanding of the parameter will help me fine tune and speed up my probing I hope. I will try to study some now since I see the light at the end of the tunnel now. Thank you Thank you Thank you.

Update, I began playing around with the height after touch to try to speed up my macnine. I believe I have found that you should not set it less than half the height of the part you are probing. I am using a trailer wire clip as the part because it has rounded top and odd shape. I will keep up with this. I have been searching to see if there is a way to dynamically change the variables with a text screen instead of having to adjust the program each time and re-save it the run again but this is just me once I make sure of the thresholds of the variables is true it will be easier to set it up first time and leave it. Thank you again.
