Hello, I am missing 2 ports for the use of Helges ROME. On my Octopus Pro 723 three slots TMC 2209 are occupied by Z and 4 slots for X and Y with 5160. I was given the tip here to use the BTT Exp Mot as a solution to my problem. After reading and testing, I got motor port 2 to work. After further research on the Voron pages, I had the answer to my problem. The pins#s PA7, PA6 and PA5 are used for the SPI bus. After I had commented out miso, mosi and clk in the aliases, the two extruders worked. But of course not the motors for X and Y. As far as I know, the Octopus has 2 SPI_Bus old: #stepper_spi_mosi_pin=PA7, stepper_spi_miso_pin=PA6, stepper_spi_sclk_pin=PA5, new: stepper_spi_mosi_pin=PC3, stepper_spi_miso_pin=PC2, stepper_spi_sclk_pin=PB13, However, this did not work. Is there a solution to my problem?
