Ok so here’s my dilemma. Im going to try and explain what wrong as best as I can.
I have the X5 mini and I’m using to control a cartesian style printer. I am using a inductive style probe like printrbot uses. I have it hooked straight up to the probe port in the X5 mini. Im not using any voltage divider as the probe port can supply 5 volts although I may change that as the probe says it needs 6 volts. I dont have z endstops. In fact I changed the gamma end stop to use the same pin as the zprobe. If I shouldnt be doing this please let me know.
Here is where my problems start. the z offset function in the config file has no effect what so ever. No matter what I try, whether it be negative or positive values nothing changes. I really honestly have no clue what I should actually be doing regarding how to get the probe working properly because zprobe documentation is frankly awful.
If someone could give me like a step by step guide on what I should do to calibrate the probe or how to properly set it up that would be greatly appreciated. It is imperative that I get this working because a group of people and I are developing a printer to bring to the market in the next month or two.

Hey !
I’m not clear on exactly what the problem is.
Can you describe in more detail what works and what doesn’t ?
Thanks !
Ill give it my best shot. So I have the probe hooked up to the probe port (or E-stop in my case) and I can run the G32 command just fine and it will probe in three different spots just fine. I changed the pin the the gamma-min uses to be the same pin as the zprobe so I can hit the Z home in repetier and home my z just fine. My problem is when it comes time to print. It prints the object in mid air. I tried setting my Z offest in order to compensate however when I do that nothing changes. It still prints in mid air. I get the feeling that Im just misinterpreting something here and not setting the right value in the right part of the config file but I’m not sure.
On a side note, thanks for developing such an amazing product Mr. Wolf. Your help really is appreciated.
A little update. I tried setting my homing offsets too and my gamma min value to negative values and its still printing in mid air. I don’t have a g28 command in my start gcode however. Not sure if that makes a difference or not.
You definitely need a G28 at the beginning of your file, or everything you have been doing means nothing.
So how should I go about calculating the z offset then?
Well first make sure you use G28 in your G-code file.
And then you can find the right offset by trial and error.
Cheers.
