using bl touch as a crude scanner

Re: 3D scanning a $2 coin with 3D printer and DIY touch probe

@CVMichael did this very cool thing turning his 3d printer into a scanner using a needle

could i do the same thing with my printer using the bltouch probe and a macro?
I get that the probe is not very pointy and that depth would be an issue as anything deep might hit the extruder, but i'm thinking something fairly flat like an odd shaped pcb would be quite useful to scan if one was making a case for it.

Or is it easier and simpler to plonk it on a fax/scanner and then do an edge detection in inkscape or similar?

@magnets99 I’d think you could do the same thing with a BLTouch for 3D shapes, as the sensitivity and repeatability is usually around 0.01mm. However, if it’s a 2D shape that you’re trying to get the outline of, like a PCB, I’d think keeping it simple and using a scanner, or taking a photo of it, would be simpler and faster.
