As an old Chilipeppr fan I know there is surface scanning functionality built in. So I wanted to share a small 3USD probe tool I made during the weekend. It enables probing without attaching conductive tape to the workpiece. Hope you like it!
Thank you. I am going to try it for carving some curved pieces.
Which cnc controller is used? Great project!
Hi Frank 
I use Estlcam as controller for the moment. http://www.estlcam.com/
No, i mean the hardware: grbl or tinyg?
Actually none of the above. I use Arduino for HW but Estlcam has it’s custom controller firmware
Awesome! How does the chilipeppr surface scanning thing work - are there perhaps any links to a tutorial or other info for a noob please?
Not sure abt chilipeppr - but regarding the design I found and even better on. Will make a new version using this approach instead - much simpler
