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?
