MANTA M8P V1.0 CB1 + TMC5160

[Pock]

I can't start the hardware SPI for Klipper

The recommended configuration does not work:

[tmc5160 stepper_x]
cs_pin: PC10
spi_bus: spi1
#diag1_pin: PF3
run_current: 1.270
hold_current: 0.800
sense_resistor: 0.033

Error pops up:

Unable to write tmc spi 'stepper_x' register GLOBALSCALER
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

with the SPI software - works properly:

[tmc5160 stepper_x]
cs_pin: PC10
spi_software_sclk_pin: PA5
spi_software_miso_pin: PA6
spi_software_mosi_pin: PA7
#diag1_pin: PF3
run_current: 1.270
hold_current: 0.800
sense_resistor: 0.033

How to correctly configure hardware SPI?

 

 

[Pock]

I found a solution

addition:

spi_speed: 3500000

solved the problem

I have not found anywhere that this parameter is critical.

Hi..were you able to configure sensorless homing by any chance?

[Pock]

I haven't tried it yet, but I will try in the future. I have to connect "Diag Pin" with the motherboard. And it should work.

spoiler alert: it doesn't work.

I think...the SPI1 bus is used by TMC5160 and when I try to use ADXL345, the bus is busy... I thought I was using the spi0 bus on the 40pins
