Re: Experimental MAX31865 on Marlin

Hi, i have a MKS GEN L v.1 board, which is basically a RAMPS 1.4

i have tested my MAX31865 board + PT100 3 wire version with Arduino Uno and Adafruit example file and all works fine. Therefore I can exclude an error on the MAX31865 board

1. I have wired on MKS Gen L Aux 2 top row = GND, 63[sdi], 40 [sck], 42 [sdo], 65 [cs]
2. copied temperature.cpp in Arduino folder
3. install Adafruit library MAX31865
4. in configuration.h
#define TEMP_SENSOR_0 -2 // MAX 6675
#define MAX6675_IS_MAX31865

I have disconnected my before thermistor from MKS Gen L, therefore Pin 13 is empty

Compiled, upload is ok, but directly Marlin throws the ERR: MAXTEMP

My intuition tells me, that the empty PIN13 makes the problem.

Do you have an idea how to troubleshoot?
