Hello all ... I´m new in this forum.
I have problems to get MAX6675 to work on the following configuration:
latest Marlin bugfix-2.0.x FW on REARM board with Ramps 1.6 addon ... REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is connected and enabled, SDSUPPORT is diabled.
After turning on the power, the bootscreen shows up, then it shows a broken "status" screen and it is beeping, followed by a constant tone and a message on the LCD "temp. on E1 to high ... Printer stopped".
Only one Hot-End is enabled.
I searched the whole code, but couldn't find the place where the SPI pins for the MAX6675 are defined. In my opinion I have tested all SPI pins that can be found in the REARM pinout. Error also happens when MAX6675 is not connected at all.
I also tried to enable SDSUPPORT but the problem remains. With LCD and SDSUPPORTdisabled no connection to the board is possible.
I hope someone can give me a hint :-)
