Remora - Rpi Software Stepping Using External Microcontroller via SPI

Doesnt come out of estop for me with the new remora.c with lpc1768 and stm32f407vgt6
Just curious are you using a rpi3 or a rpi4 ?

Hi, thanks for the feedback. I've fixed a logical error in the SPI comms. Tested on LPC1769 and pushed to the develop branch.

I use both RPi3 and RPi4, but use RPi4 for my large printer so as to handle million line g-code smoothly in the Axis GUI.

same for me : Bad SPI payload = f6fdfffd

"stm" is for 168mhz and "STM" is for 180mhz ?

Edit : it works on the lpc1768 but not on the stm

Hi, please download the latest firmware and remora component. I pushed some corrections today and have confirmed on both STM and LPC boards. The "stm" and "STM" is just to make the command line more forgiving and nothing to do with the version or speed of the STM32.

Hi All, What are the chances of remora working on a STM32F401? These Dev boards are like $4 on aliexpress.  I think they only 72Mhz though. or otherwise the ESP32 via SPI? ( The ESP Vroom) boards are also a nice dev board.
Thanks

 

This subboard might be ideal STM F 3 Driver slots with TMC support IO and most important SPI header and cheeeeeeep
