ToolClamped input will be available for Acorn/Acornsix in V5.40.00. Hickory already has the input.

Though adding a check in the current v5.30 macros to check whether the input is made or not is very simple as well.

Thanks for the heads up. Now I can put that extra proximity sensor to work!

no preprogrammed wizard input is needed to do this.

Marc,

Thanks for the great tip on the rectangular, top sensing proximity sensor. It totally saved the day. Here it is working perfectly.

I can't say thank you enough!

You made my day!

Nice. That was a quick turnaround to get the new arrangement up and running.

Yes, I was rather unhappy when the initial design did not work. After you sent me the link from Automation Direct, I downloaded the 3D model of the proposed proximity sensor. By the time I got the new sensor, I had already redrawn the brackets, spacers etc. It all fit together perfectly.

I am late to the party and its not what you want to hear but I highly suggest you do not put the sensor under the tray. I had mine tucked under and a chip triggered it and the mill grabbed the wrong tool. This happened twice before i put it on top, I am talking twice per thousands of tool changes but it just takes one time for a bad day. I still have the vise jaw with a 3/8 hole in it

Wow... I never would have thought about that. Thanks for the heads up. Do you mind sharing an image of how you accomplished moving the sensor up top. I can't imagine an easy fix for this at all.

The only thing I can think of is use a double shaft stepper motor and put the proximity sensor and cam on the other side of the stepper. I just need to
think a creative way to do this.

Just purchased a dual shaft stepper. Looks like a fairly easy modification. Thanks so much for pointing this out to me!
