Remora - Rpi Software Stepping Using External Microcontroller via SPI

It can be made to work most likely, with SPI. I dont know about the ethernet though, or if the GD-407 will work.

Cant do this anymore bye all wrote:

Would Remora work with this ?

The STM32 Remora-EC500 code base would be a very close starting point. The EC500 uses a different version of the F407 so pin assignments would need to be checked.

Cheers mate.

What version of STM32Cube would you recommend ?

Hi cakeslob,
I have used your repository github.com/cakeslob/Remora/tree/nucleo_staticZE .
Thanks for your implementation for Nucleo 446ZE.
I am sharing the video for the issue.
In MDI I hit 5 mm, the stepper moves slightly over 5 mm then it retracts to commanded position of 5 mm.

Hi cakeslob!

I'm finally at the wiring and controller stage of my build and so I'm picking this back up.

Still trying to use the Spider king board and big TMC5160s

I put the firmware.bin file on an SD card and popped it into the spider king. Flash led (red one on the core module) flashed on off for a while then stopped. On reboot there is lots of something going to the serial port but none of it is human readable? I used an Arduino to read the pass the serial to a terminal on my pc like you would a UART to usb adapter.

Is 115200 the correct baud rate? I'm connecting to the Rx/tx pins on the raspberry pi connector on the spider king (I remember that it doesn't use the usb ones by default)

How do I debug before trying to connect the SPI?

Cheers for your work!

hey viren, add these deadband lines to your ini and hal for each axis. you may need to adjust the values a little
