Hello! I have a ramps 1.4 and an RRD fan extender is taking up all the servo pins. I would like to be able to control a servo for Z-probing. Where can I connect the servo instead of the "servo section"?
Or you could use my IR Z probe - as used on the E3D BigBox printer and the T3P3 Mini Kossel - which is smaller and lighter than either a servo probe or an inductive probe. See [www.escher3d.com].
