General Mach Discussion / termine tool length

« on: May 01, 2011, 12:52:19 PM »

hi
I have little experience with mach3. I like to determine the tool length automatically. I read a few threads and some vb scripts but not with the success I expect. I have the following in mind:
-Moving spindle down in z; -hit some switch; -determine the tool length.
what I did so far:
-I found some input in the Break Out Board which is not used and connected it to a switch.
-when i move the z axis and hit the switch then there is a e stop and I get a correct z value in the DRO but I have to press Reset to continue to work.
-the diagnostic shows input on Input4 and LED is turned on
-If I run one of scripts using G31 then the script runs on a exception (unexpected return from script (Reset))

I understand so far what is happening but how can I make that the switch on x-- on input4 is not going into an e-stop. Can I set some event handler to input4 to handle the switch myself or is there a simpler way.
I am glad to get an answer from somebody fighting with similar problems. thanks
