Manta M8P with Biqu H2 500c

[kishmj]

Hey everyone. Hopefully someone can help me out. 
 

I am using the Manta M8P with the cb1 and I’m trying to set up the klipper printer.cfg file so I can use the Biqu H2 500c. This is a fresh build so I am building my file as I go.  I am unable to configure the max31865 driver properly.  I keep get an spi error. Can anyone point me in the correct direction or share their config file with me if they have this set up? 
 

Thank you in advance. 
Your name always comes up Tony so maybe you can help?

Kishmi,

 

I struggled for a while with this issue also.

 

Here is what I found out.

 

I put my Max31865 in motor 8.

I changed the jumpers from uart mode to SPI mode  (see attached Picture)

 

Make sure that when you attach the thermistor to the board, you connect it to the 2 center pins  (as shown in picture)

My printer.config file looks like this.

[extruder]
step_pin: PC9
dir_pin: !PC8
enable_pin: !PD1
microsteps: 16
rotation_distance: 3.4334
nozzle_diameter: 0.4

heater_pin: PE3 # HE0

sensor_type:MAX31865
#   One of "MAX6675", "MAX31855", "MAX31856", or "MAX31865".
sensor_pin: PD10
#   The chip select line for the sensor chip. This parameter must be
#   provided.
spi_speed: 4000000
#   The SPI speed (in hz) to use when communicating with the chip.
#   The default is 4000000.
#spi_bus:

#   See the "common SPI settings" section for a description of the
#   above parameters.
#tc_type: K
#tc_use_50Hz_filter: False
#tc_averaging_count: 1
#   The above parameters control the sensor parameters of MAX31856
#   chips. The defaults for each parameter are next to the parameter
#   name in the above list.
rtd_nominal_r: 100
rtd_reference_r: 430
rtd_num_of_wires: 2
rtd_use_50Hz_filter: False
