The grad students in the lab next door have to sit meticulously for hours/days with dental drills drilling out samples from rocks. I was hoping to be able to automate it with an affordable CNC machine (and an attached scanner bed) – but I seem to not be able to find any clear information about step sizes. Here it says microstepping is bad....
I also don't really need to do any milling, just adjust to the right x-y position and punch a tiny hole and collect the dust. Milling rocks in any case is a no-no from what I understand. Maybe someone could suggest some ideas for my .. unconventional requirements :)
The samples are pretty small (maybe 20cm^2 at the most) and I don't need to do it fast... And I prolly don't have a huge budget
