Is there a program for scanning surfaces on a 3D printer?

Question

3D

You need a program for scanning the surface on a 3D printer, Marlin firmware. The foil wraps around the scanned object, a wire is connected to it. Another wire to the probe. The probe is released onto the scanned surface. When closing, a signal is received, the probe stops, rises, goes to another point and the actions are repeated. The result should be the coordinates of points and heights with the required resolution.

In general, coordinate measuring machines (CMM) are used for this, which work a little differently. Under them there is the darkness of everything: Siemens NX CMM (there is an SDK for it, by the way), Nikon CMM Manager and so on and so forth.
On the topic of building a CMM based on Arduino, there are huge forum threads, I haven’t seen anything ready-made, and even more so universal, really. Perhaps now someone has already vouchsafed. I suggest rummaging through the forums on the Arduino CMM.
And if you figure it out like that, then getting an array of coordinates for building a point cloud is not so difficult by directly making changes to the firmware itself. For example, by rewriting the procedure for handling the operation of an additional limit switch. Not a model, but building it on the cloud is not a problem, moreover, it will be possible to correct the normals at the points at the construction level and trim the extra points right in the process.
