Here is a link for the mini proximity sensor I use:
http://jimou.en.alibaba.com/product/...ty_sensor.html Type 10-30V NPN N.O. with a switching distance of 0.8mm
I also noticed (especially when using mechanical switches) that slowing down the second and final probe movement increases the accuracy significantly. I therefor patched the ‘homing_feedrate[Z_AXIS] ‘ lines within marlin_main.cpp to be divided by 8 where the default is only 2. This makes a notable difference. Even for a non-mechanical sensor such as an induction proximity sensor.
