Then it's most likely noise, and the cap should help.
In this case, I favour trying a pullup on the input first. This is often enough to overcome false triggering in this case.
Remember that there is no spindle running and little axis movement when auto zeroing as opposed to a limit input.
A limit input is watched all the time by Mach while there is lots of electrical stuff happening and a capacitor is often the answer.
Auto tool zero input (probe), is only watched by Mach while G31 is in motion and not much else electrically is happening.
The tiny signal delay introduced by the capacitor is less desirable when wanting an accurate zero routine. On a limit it does not matter.
So sure use a capacitor if you must but try a pullup first.

I think I will try both the capacitor and the pull up on the board (whichever works first wins). I think I also will upgrade the cabling to shielded as well. Thanks for the help.
Update: Capacitor worked. Everything now works great. Thanks! What a great upgrade to my system!
I would upgrade to shielded cables first.
It it is always a good idea.
Another happy customer.
I am a bit confused as to the tool setter procedure. I load my G code, initial zero (zero's both fixed and mobile touch plates), and hit cycle start. Almost immediately I am asked for a tool change. I hit cycle start (since this is the first tool and tool I zeroed with) and job starts cutting. Mach is not stopping or asking for the next tool change, it just keeps cutting with the original tool. I am using VCarve Pro 5 to create G code and have tried Mach inch and Mach inch ATC post processors. What am I doing wrong?
Thanks,

As there more than one M6 in your g-code?
Are you selecting multiple toolpaths when you export your g-code?
It sounds like you're only exporting a single toolpath.
The default Vectric post outputs a toolchange (M6) at the start of the code. This is needed for a machine with an ATC, but for use with the Big Tex macro's, I modify the post to remove the first tool change.
The only M6 command is the one at the beginning and yes I am selecting multiple tool paths. With Mach inch it gives a warning with multiple tool paths but I ignore it and write code anyway and with Mach inch ATC it processes normally (I tried both and only 1 M6 code in each) Are those PP's the ones I should be using? If necessary, could I insert a M6 command before each tool change and what code should I enter ?
Do your toolpaths use different tools? If so, the ATC post should include the tool changes. If it's not, you might want to ask on the Vectric forum. They'll get you sorted out pretty quickly.
I am so close! All goes well until I use second button to zero tool. Tool moves to fixed touch plate and touches off and moves to zero and does not wait for cycle start, router pauses and then goes right to tool path and starts running. Is there a setting in Mach I am missing. In gen config I have set "Stop spindle wait for cycle start", "Stop on Mo1 command".
Thanks,
Stuart
Thanks
Post the beginning of your GCode file.
I don't have the current Big Tex version installed, but I think it's supposed to do that.Quote:

Go to Operator > Edit Button Script, then click on the Tool Change Zero Setup Button. When the script editor opens, delete the 2nd from last line:
Code DoButton(0) 'Cycle Start
Then File > Save, and close the editor.
It should then work the way you want.
Gerry,
That did the trick. Thanks very much!
Stuart
That would be correct, it's supposed to do that.Quote:

When you load g-code and M6 comes that makes machine ask for tool change.
I have tool changing location indicated so machine comes to that location.
If my tool is zeroed I hit cycle start if not I hit tool zero (Alt+Z) and off she goes. I did this for a reason to minimize actions required by an operator.
Garry got you in the right direction.......
Thanks for the reply. It really is an excellent screen and set of new tools making my machine a more consistent and accurate setting z.

That is the pointQuote:

Current is fine.Quote:

Simple as that
