Need Help adding 3D Touch Auto bed leveling to RepRapGuru Prusa I3

I have a RepRapGuru Prusa I3. It has an Arduino Mega 2560. I am trying to add a 3D Touch auto leveling sensor. I have the connections that I need made. However, I need help with the Marlin V2 Sketch software to use the sensor.

If it is indeed a 3D TOUCH instead of a BLTOUCH, then you bought a cheap, Chinese knock off of the Bltouch, which violates their patent. They are notorious for not working and they will not be supported. That being said, the latest marlin firmware 1.1.0 RC8 works fine and supports the BLTOUCH directly. You still have to do some work like the x, y, and z offsets though. That's in YOUR hands.


Folger Tech 2020 i3 and FT-5. Both running the BLTOUCH.
Great kit. Having fun and running the heck out of it.
Running Marlin 1.1.0 RC8 on the i3 and 1.0.2 on the FT5.

Thank you for the information. I did unfortunately get sold the 3D Touch instead of the BLTouch. I have already fixed that by ordering the real thing. I am currently running the RepRap_Guru_Marlin_V.2 firmware. I will need to dive into changing over to the root Marlin 1.1.0-RC8 version as i can't find code in the RepRap version to handle the sensor. The offsets shouldn't be too killer to deal with after that. Again thank you for the information.

What did you use to mount your 3D Touch? I'm considering buying a BLTouch, for my reprapguru prusa i3, and if you already have a bracket designed, that would be great.

Thanks.
