Good morning everyone!! I have a Geeetech 3DTouch installed on my machine with a GT2560 card configured according to manual and firmeware .It works perfectly in your readings, but during printing the sensor shaft falls on the desk and risks breaking over the part that is printing, someone knows Tell me how to fix this problem. "The LED is lit and the axis falls on the printing table" I will be very grateful if someone can help me !!

Do you screw the axis tightly? and do you add the sensor to printer by this fixture seeing on the picture.

Good Morning !! I think I could not express myself right !!. When I am printing the sensor pin lowers on the table as if probing and does not retract with a risk of hitting the part I am printing!

Hi,

I understand what you meant ^^ I configured from scratch Marlin 1.1.4 (<-- see my link) to work with 3Dtouch (or original BLTouch) and I had the same issues at first tries. You have to configure pins in firmware and Z-min connector way (direction black white wires) for old boards (not Rev A+), you have to set pin numbers (where is connected your probe for your ATMega board) in firmware to the value 32 , so #define Z_MAX_PIN -1 and #define SERVO0_PIN 32 in source code... For Rev A+ boards, Pin value is 11...

Regards.

Maybe your probe is not well calibrated... Watch my thread here to see how to fine tune and calibrate it... When top screw is not at the right place you can have such behaviours...
