Setting tool setter offset (for large bits)

I’m wondering how I can set the tool setter in masso to offset the probe location based on the bit diameter.

I have to set on center which works for small EMs. However, for larger bits, such as a 2-1/2" surfacing bit I use, it doesn’t work at all at this location as the cutting inserts are out on the edges outside of the tool probe touch area.

How can I set this up properly so it adjusts the position so that the tool touch probe is centered over the bit outer diamter?

Masso does not allow for multiple programmed tool setter locations.
When I want to determine tool offsets, I just change one axis value in the auto tool zero popup - the Y axis position in my setup. It takes a few seconds to change and save, then again to reset to the preferred coordinate for regular use.

Not ideal, and in my case less of an issue as I have an ATC and only need to do it once to establish offsets for all my tooling.

This seems like a bit of a miss to not have some kind of functionality here, such as allowing a programmed offset for a specific tool. In this case, to use this tool in a program (without an ATC), I have no idea how you would do it as I don’t think you can manually change that setting mid program when switching between a larger dia tool and a smaller tool.

For example, I have a job coming up to machine some 4x4" mortise and tenon posts, which would be surfaced with the 2-1/2" bit then the mortises hogged out with a 1/2" EM. It seems like the only workaround would be to move the tool to a different program, change the setting for every bit change, then change it back and load the remaining ops?

You should request this on the Masso forum. Masso does not monitor this forum.

I need to embed my Onefinity tool setter in a very specific location on my spoilboard, which will require some machining that I’m not quite ready to do. So as a workaround, I configured my Masso controller to use the standard 3D touchprobe for a tool setter. I got the idea from this CNCNutz video, in which he uses a simple rectangular block of aluminum as a touch probe.

If that approach would work for your large-tool jobs, it’s easy to swap the tool-setter function back and forth between the two sensor devices. Here’s how I configured mine:

  • Install a jumper wire between input 12 (default Probe) and unused Input 10 (default Unassigned).
  • On the F1 screen, set input 11 (Default Tool Setter) to Unassigned.
  • On the F1 screen, set input 10 to Tool Setter.

You can see my jumper wire (yellow) in the photo below. Note that, just like when using it normally, the ground lead of the touch probe must have electrical continuity to the bit. On my machine, I’ve found that I can simply leave the magnetic lead stuck to the head of a motor-mounting screw.

Then, when you want to revert to using the Onefinity tool setter, simply go to the F1 screen and change the input 10 and 11 functions back to their defaults. And of course you’ll need to revert the tool-setter location as well, unless you can place the touch probe over top of your tool setter.

Even after I get my tool setter mounted, I’m going to leave the jumper wire installed in my controller, specifically for compatibility with large bits.
