I had to replace my original GT2560 Rev A board and received an Rev A+ board. I'm trying to connect the 3D-Touch to the new Servo pins (next to the temperature sensor pins) and cannot get it to work. The 3D-Touch on does 2 of the 3 extensions and can't be controlled by the M280 commands. I had this working before so I know how this should be acting. I purchased another Touch sensor and am having the same problem with the new sensor.
This is making me crazy! Please help.

Re: GT2560 Rev A+ / 3D-Touch Problem
Hi William.
The issue has been resolved but the solution is not correct. As it turns out there is not a problem with the self test. What is the the issue is that the A+ board maps the SERVO0_PIN to 11 instead of 32. Since the A+ board leaves the ZMAX_PIN available there is no need to use its connection. It would be great if Geeetech would update the Marlin setting on the 3D-Touch with this new information.
