Thanks for the replies everyone! It is very helpful.
I am actually making a touch plate already, the touch probe is something that interest me as well. This is less about what is needed, and more about what am I good enough to make. Self challenge if you will. I’m currently enrolled in an program and have access to big machines so I’m trying to take advantage of this by having projects on standby.
I’m currently designing a touch probe and I have it around 2’’-ish in length, so next step is to 3D print and test.
This is probably 4th on my list, behind a wall of workholding things for the nomad.
