pin EXP2_1 is an alias for stepper_spi_miso_pin

Trying to use mini12864, but when i setup it on printer.cfg I am getting the message from the tittle. [display] lcd_type: uc1701 cs_pin: EXP1_3 a0_pin: EXP1_4 rst_pin: EXP1_5 contrast: 63 encoder_pins: ^EXP2_5, ^EXP2_3 click_pin: ^!EXP1_2 Some micro-controller boards may require an spi bus to be specified: #spi_bus: spi1 Alternatively, some micro-controller boards may work with software spi: spi_software_miso_pin: EXP2_1 spi_software_mosi_pin: EXP2_6 spi_software_sclk_pin: EXP2_2 [output_pin beeper] pin: EXP1_1 [neopixel btt_mini12864] pin: EXP1_6 chain_count: 3 color_order: RGB initial_RED: 0.4 initial_GREEN: 0.4 initial_BLUE: 0.4 If I try with SPI1, I am getting the error message: pin stepper_spi_miso_pin is reserved for spi1 [display] lcd_type: uc1701 cs_pin: EXP1_3 a0_pin: EXP1_4 rst_pin: EXP1_5 contrast: 63 encoder_pins: ^EXP2_5, ^EXP2_3 click_pin: ^!EXP1_2 Some micro-controller boards may require an spi bus to be specified: spi_bus: spi1 Alternatively, some micro-controller boards may work with software spi: #spi_software_miso_pin: EXP2_1 #spi_software_mosi_pin: EXP2_6 #spi_software_sclk_pin: EXP2_2 [output_pin beeper] pin: EXP1_1 [neopixel btt_mini12864] pin: EXP1_6 chain_count: 3 color_order: RGB initial_RED: 0.4 initial_GREEN: 0.4 initial_BLUE: 0.4 I am using two tmc5160 in SPI mode for X an Y Board BTT Octopus PRO 446 Any clue?

Just use "stepper_spi_miso_pin" in place of "EXP2_1".. You'll prolly get the same for mosi and sclk. Same thing, just use the stepper_spi_whatever alias instead.
