EZ31865 with Octopus Max EZ?

[Alex LaVelle]

Has anyone actually managed to get this setup to work? BTT support is useless on this topic and the manual shows outdated pin assignments that are rejected by bugfix 2.1.x.

Both temp sensors are set as -5.

I commented out E4 and E5 pinouts and reassigned to:

#define TEMP_0_MISO_PIN PE13
#define TEMP_0_SCK_PIN PE12
#define TEMP_0_MOSI_PIN PE14
#define TEMP_0_CS_PIN PG8

#define TEMP_1_MISO_PIN PE13
#define TEMP_1_SCK_PIN PE12
#define TEMP_1_MOSI_PIN PE14
#define TEMP_1_CS_PIN PG7

 

I've uncommented:

#define TEMP_SENSOR_FORCE_HW_SPI
#define IGNORE_THERMOCOUPLE_ERRORS

#define MAX31865 IGNORE_INITIAL_FAULTY_READS 10
#define SHOW_TEMP_ADC_VALUES
#define M115_GEOMETRY_REPORT

 

I've tried forcing HW SPI and conversely tried forcing SOFTWARE_SPI.

 

I have 2 EZ31865's plugged into EZ slots for motors 9 and 10. I have 2 PT1000's plugged into the 2 middle pins on the M9 and M10 motor slots.

 

No matter what I do, the board won't connect. I assume due to a temp error forcing it to shutdown.

If I revert back to temp sensor 1047 for both sensors, it connects fine but only displays 1 temp. The other temp says 0 despite both sensors showing identical resistance. There seem to be no guides or support post anywhere so I'm at a loss here.

 

Will absolutely venmo anyone who knows of a solution $50 to stop me from ripping out more of my hair.
