A new Compact opto-servo probe. This time starting from Japim's idea of using 3.7g micro -servo I have reduced the height to BL Touch height and I have adapted the flag and spring from my Compact opto servo probe.
Assambling instruction in the pictures. Spring is optional. In the video I didn't use the spring.
Wiring and firmware modifications are the same as explained in "Compact opto servo probe".
The accuracy and repeteability is the same as previous version ( standard deviation around 0.0015).
A short videos: Accuracy  and ABL test
3d model view.
I have designed in Designspark free and export to step file it is not available.

With #define DISABLE_M503 active in Configuration.h, Linear Advance can be activated in Configuration_adv.h .
