This is a common issue. And we need to clean up how this is configured. (But that won't happen until after the Release Candidate goes Golden.)
It is being caused by a mis-understanding on your part how to configure the Z-Probe. The firmware doesn't know to be watching where ever you have the probe plugged in.
Do you have a Z-Min endstop? If so this complicates things (but it still can be configured). If you are just using the Z-Probe then the easiest way to get running is to enable:
Code:#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

I only have the one capacitive sensor. i had before, the servo and microswitch. Its working in the sense that I have the sensor basically zeroed at the print height. had to adjust and raise and drop many times but, its there.
Will there be a way in the future to use the sensor in the endstop format but, disable its use after homing or running a G29?

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.Last edited by Roxy; 06-01-2016 at 03:17 PM.

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!

Typically, the inductive and capacitive sensors are mounted above the nozzle. But they trigger before the nozzle touches the bed.
Do you realize this? Is this what your sensor is doing? Because if it isn't doing this, you probably want to change its height.

i just adjusted the sensor to be at the right height.

Following up, I know its been quite a while. The sensor I bought, has proven, at least im my usage, to be garbage. Tonight, I was trying to print somehting in PLA. Nothing would stick, the bed didnt seem level. Fixed that, the nozzle height seemed to change from one print to the next although the print is starting int he same position. I think I am going back to a servo and micro switch. The sensor, during a heating cycle of the bed, would light up and go out, telling me that the probe was not close enough, level, etc. It was right in sync with the bed relay turning on and off.
I cant wait for the wife to approve a complete rebuild. Friend of mine is goiing to help me make a TAZ clone. The current printer is a Makerfarm 12" i3v. Wood sucks mmmkay?
