I have a cheap ebay $100 probe. I had doubts about the accuracy, so I perfomed a test probing a precision disc from all orientations. (The disc came from a 1"-2" micrometer - it is used to "zero" the micrometer).
The results were pretty poor, with the error ranging from 0.3mm to 0.75mm. http://www.franksworkshop.com.au/wordpress/2019/03/01/touch-probe-accuracy/# results > I have no way to measure how good MY probe is. _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
