Using the same connection for the KP-1 and TT-4 <Answered>

[Cogswell]

To whom it Concerns,
I recently installed the KP-1 and used an aircraft style 5-pin male/female connector to install. I wired the female connector to the Acorn board per the Acorn_rev4, KP-1 Probe Drawing Filename:S15262.DWG. I will be purchasing the TT-4 soon and would like to be able to use the same female connector to plug either Probe into. The drawings show both the KP-1 and the TT-4 utilizing the same inputs of Input 6 and 7. When in the Wizard it shows selecting the TT-4 Input drag and drop for Tool Touch Off Detect as Input 6 and the Tool Touch Off signal as Input 7, however these inputs are already occupied with the KP-1 Probe Detect on Input 6 and the Probe Signal on Input 7. Please help.
Very Respectfully,
Steve C

You should be able to use the same input for the trip signals for both devices.

You have to assign, and wire, their detect signals to different inputs so that CNC12 can tell which device is plugged in.

So you need a total of three inputs. They can be any three inputs. INP6 and INP7 are just examples. You choose which inputs you are really going to use in the Wizard.

If you want to use the same input for both devices they would have to both be normally open triggers. I have my small router set up with a movable tool touch off and my probe wired to a single input set as "probe tripped". Both devices are NO. I've never used the KP-1 or the TT-4 so I can't speak for their trigger types. You'll need a second input set as "probe detect" so CNC12 knows which device is plugged in to the machine.

It can be done with only two inputs but the devices need to both be NO. Otherwise you'll need three inputs but you can still use the same 5 pin connector you have. When you plug in the probe you'll need to have it short the "probe detect" input to ground.

I am wanting to purchase Swissi’s CHIPS for the Acorn setup for my Mill. I see an advantage to wiring them as two separate devices to be able to utilize both together for calibration etc…I have open inputs, so it will be simple. Thank you both cncsnw & ShawnM for your inputs.
