Remora - Rpi Software Stepping Using External Microcontroller via SPI

Getting back to the topic of Remora SPI, I have pushed some updates to the repo to give command line options to specify the SPI number, CS number and frequency of the SPI interface for the RPi 5.

loadrt remora-spi SPI_num=0 CS_num=0 SPI_freq=20000000

Default frequency is 20Mhz, which is happily running on my Octopus, with Cakeslob's latest compiled firmware, without communication errors.

We'll need to update all the firmware to the latest. Thanks for your patience, but if there is a priority please let us know.

scotta thank you,I'll try to understand, I see that you explained the initial steps in a nice and photos way, so I'll see how far I'll go..thanks

hey scott, with the ability to select the spi channel, do you think it possible to do multiple instances of remora using separate spi channels?

What would be the best 3d printer board to use with remora spi and raspberry pi 5 please? For k40 style co2 laser, so I dont need too many motors.
