Surface Mapping

I couldn’t find anything on this subject nor a topic area that it fit into so putting it here.

Feel free to move this to a more appropriate topic area if there is one.

I was watching This Old Tony on YouTube and his latest video about surface mapping on the mill using Mach 4.

I know the Onefinity won’t run Mach4 but is there a way to do surface mapping on a CNC router using a probe such as Tony used in his video?

The Shopbot has a surface probe and functionality to read the results. I’m not aware of any way to do the same with the OneFinity at this time.

The touch plate basically does the same operation but for a single point it seems to me. It differs in that it requires completing the circuit between the bit and the plate, not identifying contact with the wood or some other non-conductive material.

If you took that ability to map 0,0,0 and expanded it out to a user defined array of points to me that sounds like the ability to create a surface map. The digitizer mounted in the collet is just a switch that changes state when contact is made. I don’t see why it couldn’t use the same connection to the controller as the touch plate.

Throw some aluminum foil on your surface and you’re good to go!

Hi @Bob_D yes there is a way but it doesn’t involve the stock 1F controller.

Features like this are software/control dependant. For example I upgraded one of my 1F machines to a Centroid Acorn control system and this software/control package does have this feature. Operations like this will require a more powerful/industrial control package.

2 great ones to checkout are Centroid Acorn and Masso G3

Hope this helps.


Have a look at this thread for some ideas

Thanks, I do not frequent the Carbide Create forum but I noticed
they’re referencing the same video by ToT that I did. :slight_smile:

But it sounds like what I was thinking of is possible, just not with
the Onefinity using the Buildbotics controller.
