Is there a video anywhere that shows how to use the KP-3 and TT-4 together to perform tool setup.

Specifically how to use them together to auto calculate the tool offsets such that those offsets are then applied when i use the KP-3 to find the part??

Acorn & ver 5.06 CNC-12

For milling not turning

i recommend you first understand how to perform these tasks manually.


once you have that solid. then you can begin to use the probes to do the same thing. once you get that down then you can (if you like) move onto more automation.

which method employed when using tool touch offs and probes is highly dependent on the machine it self (mill, knee mill, router, ATd? etc) and the work flow and even types of parts you plan on making.

Thanks, but thats not what i need.

I understand how to do thew manually and with the each of the probes separately. I'm trying to understand how they interact within the software, if they even do, such that using them together can eliminate any manual "touching" of a part or tool

I don't think that your question is being understood.

Many, if not most users are using a Probe and Tool Touch Off to set tool heights and offsets.

Setup would be nothing more than measuring the length of the probe via the normal tool length setting process.

Are you referring to the optional Auto-Measure and Batch Auto-Measure functionalities? They are described starting on page 60 of the manual.

Auto-Measure will automatically measure the height offset for a single tool. Batch is useful if you have an ATC because it will automatically measure the height offsets of the list of selected tools. That means it will pull them from the ATC and measure without the operator having to manually jog or switch tools.

Tool height offsets are then often called out in the G-code program with toolchanges. The applicable codes are G43, G44, and G49.


KP-3 stylus tip diameter should be stored in a tool offset. Typical Centroid procedure is to use T10 and offsets H10 and D10 for the probe. You can then use the automated probing cycles to set part zero. Tool height offsets and cutter compensation can be applied in the G-code.

If you are looking to include part probing as part of your CNC programs, AFAIK, Centroid does not directly support this, but you could easily call the probing programs as subroutines in your CNC program.

Centroid does provide "probing" g-code support: see M115/M116/M125/M126 in the operator's manual. If your CAM software supports this, you could add part probing there.

I think this answers my question

If you wish to include Probing within your Gcode programs at each tool change, take a look at Swissi's ProbeApp on this forum which includes a modified M6 (mfunc06.mac) precisely for this purpose.

Cool, I just think people don't know exactly what you're asking which is why the replies are all over the place. If you are asking how to use the 2 items in conjunction with each other, that is simple, and as expected.

Tool Offset Library - Start with your Z reference. I recommend the top of travel (True Z0/home).
Then measure all your tools.
Then measure your probe the same way.

That's that. Now probe the part for Z, and Acorn will adjust the heights relative.

How do you setup the probe if both the Probe and the Tool Touch off device are Switches? My Z Ref is Home, if i use the Probe to set Z WCS then how does it offset the tools? If i try and use the TT device to set the Probe Offset it trips them both, or one or the other first which would be inaccurate.if i want to use the Probe to setup part, how do i do that in a way that it offsets/changes tools accordingly? Thanks
