Need Recommendations for a simple non-contact Z-Axis probe

[bzmotoninja83]

I finally got it working. Black wire from probe goes to the first pin on the plug. Now, i need to find out how to disable the probe after leveling...... Other wise, the print will not start at the desired height.

Perhaps Roxy you could assist with that?

Decided to just adjust the sensor to where zero is right where the print height starts.

I've only just read this post thought I'd share a distance sensor I was planing on using its an omron ee-spy302 it is a phototransistor senses up to 4mm and has a very wide input voltage range (5v to 24v) they are quite expensive if you get them from mouser, farnell, RS etc. however you can find them for a couple of quid on ebay if you get them shipped from china, I have a couple but haven't got round to using them yet.. I'm not a fan of the resistor divider I think I'll use a relay and optocoupler to interface with my control board!
