3D Touch Issues

[joolz]

Hi,

I am having issues getting my 3D Touch to work with my Geeetech i3 Pro B, I have followed the documents and soldered the three pins on my GT2560 and connected up the cables.

I have used the Marlin 1.1.4 firmware with the 3DTouch settings changed and adjusted the X, Y, and Z.

When I power on the pin pops out twice and then the pin stays up and the red light is on NOT flashing.

When I issue a G28 command the extruder starts and moves down towards the bed but just keeps going and does not stop and I have to power off.

If I issue an M command nothing happens except M119 which returns open for X, Y & Z.

Also I have noticed that the Marlin firmware downloaded does not have a "pins_GT2560_REV_A.h" file is this correct?

Thanks for any help and support

Julian

Do you have the rev A+ board? There are some dedicated pins next to the heater screw terminals which means you dont have to de-solder anything. This caught me out for days.
