Hi all. I have had a string of problems trying to get my GT2560 and Geeetech Aluminium Prusa i3 working but have gotten so close. I found someone who had the same config as mine but with custom firmware here >[www.geeetech.com]

The problem is, they have BLTouch enabled and I don't have that. If I upload the firmware anyway, it looks like its running fine but the x axis controlls the z axis and the y seems to be the only control that is working.

It's mentioned to comment out the touch part of the code but all I get are errors when trying to compile again! Maybe this is interfering with the pins??

This is the firmware I downloaded: [www.geeetech.com]

I'm using the latest Arduino IDE on Windows 10 (Version 1 did not want to compile at all).

The firmware you linked has a ultimaker board defined in the config.h, i think this has a totally different pinout than a GT2560.

So the boards.h I have does not include GT2560. The newer version of Marlin does however, so I copied over boards.h from there and the pins file for my GT2560.

I changed the motherboard to GT2560 in config.h file but now when I go to compile it says;

* Require some kind of probe for bed leveling and probe testing
*/
#if HAS_ABL
#if ENABLED(AUTO_BED_LEVELING_UBL)
#error "Unified Bed Leveling requires a probe: FIX_MOUNTED_PROBE, BLTOUCH, SOLENOID_PROBE, Z_PROBE_ALLEN_KEY, Z_PROBE_SLED, or Z Servo."
#else
#error "Auto Bed Leveling requires one of these: PROBE_MANUALLY, FIX_MOUNTED_PROBE, BLTOUCH, SOLENOID_PROBE, Z_PROBE_ALLEN_KEY, Z_PROBE_SLED, or a Z Servo."
#endif
#endif

The original poster said to comment out BLtouch if not using but every time I try this it doesn't work. There's plenty of youtube videos on how to get BLtouch working but can't disable it in the code I don't use auto bed leveling?

I have solved this problem by finding another firmware, the 1.1.8 firmware now uploads to the board fine. Thanks for helping anyway.
