The probe it's connected to pins 2 and 3 and the repetier response is correct when I send M119. You can see in the video that G29 don't work properly but this is not always like that. Some times the probe touches the bed and respond correctly. It start to fail and growl at the en of the g29 process losing the correct position. When g29 is done if I send G1 X0 Y0 Z2, the extruder don't stops at the center of the bed, it continues to the edge of the bed.

"The probe it's connected to pins 2 and 3 and the repetier response is correct when I send M119"
What I mean 1and 3 is as the picture shows.
And make sure the probe is assembled on the right side of the spider, not left, like this:

Yes the conection of the probe its correct and its mounted on the right side.

Here Are the pics

Nothing to do. I have change the belts, try calibration adjusting tensioners in several positions and the result is always the same. Growls and teeth skipping are impossible to solve. Money and time wasted.

Why not forget about G29 these days and start print without it, it will make you feel better.

I´ve try to print lock ring for auto level probe. The printer loose the head position when skips teeth and start to print 10 or 12 above the bed.

following your advice, I decided star to print. After some adjust with belts and tensioners I have get to print if the pieces to print are small. I start with the lock ring of the probe. I will send you a picture for the result after 11 min of printing....
I´m sending too a platform printed with Prusa I3 that I have built for a friend.

Is your extruder jammed or temperature too high? Do you have a video here?

I don't think the extruder be jammed this was my second or third try to print. I´m trying to print at 200º-205º using the PLA sent with the printer.
