GT 2560 Rev a+

Hello everybody,

I am trying to connect an inductive sensor on my GT2560 rev a + card with the "servo" connector.
Can you tell me how?
What is the signal to receive "S"? And how to activate it in the firmware?

Thanks a lot for your help.

Did you notice the 3-pin connector?

The "S" pin is a servo pin and connected to the pin11 of the mainchip.

Good morning,

I installed the wiring as indicated in the photo, I made the changes in the firmware and it does not work. Sending GCODE manual code and no response.

What could be the problem??

I have done many tests and the problem is that S connection is not enabled. How could one enable ??? Is there a bridge on the GT2560 that enables it? Or maybe the firmware ??

@i72rugoa
Did you modify the code in "pins.h" correctly?Maybe you can attach this file.

I have the same issue and have tried all firmware from 1.1.3 to 1.1.6 and the 3D Touch will not engage at all other than when printer is powered up. I have an accual programmer that will help if I can get the pin mapping of this board. Anyone have this?
