Could it be your SPI SCK frequency?

Multiple Devices on SPI Bus not working (TMC Steppers and Display)

Spent some time investigating with other devices today. Configured a Pi Hat SH1106 4wire SPI device via Software SPI and found a stable config. Moved pins around to be Hardware SPI and the display and TMC did not function. Besides the MKS Mini display being a uc1701 chip and the Pi Hat being SH1106, the MKS mini display has a 4050 buffer ship on the in bound SPI to the Display and SD lines. I started digging into SPI lengths, etc, and only discovered that, in theory, this “should” work. Di…

Your klippy.log indicates you used
spi_speed = 1500000
and
spi_speed = 500000

I would give

spi_speed: 4000000

a try here Configuration reference - Klipper documentation.

Good luck, hcet14
