Hello all … I´m new in this forum.
I have problems to get MAX6675 to work on the following configuration:
Marlin 22.214.171.124 on REARM board with Ramps 1.6 addon … REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is connected and enabled, SDSUPPORT is diabled, TMC2130 at X-, X2-, Y-, Y2-Axes.
I tried all combinations for connecting the MAX6675 to the Ramps i found on the internet but everything i found was for Mega2560. I didn´t found anything for Ramps in combination with a Re-ARM. I tried to find the right pins in the marlin code, but i´m a mechanic and programming is not realy mine.
There is something about a Software (Private) SPI but i don´t know how to activate it.
Anytime i start with MAX6675 activated in configuration.h i get an low temp. error on start.
After setting up the TMCs i thinked i could use the same software SPI but also didn´t get it running.
So my main question is were to connect the SPI Pins of the MAX6675 to the Re-ARM.
And maybe how to use same SPI pins used for the TMCs.
I hope someone can give me a hint
