Remora - Rpi Software Stepping Using External Microcontroller via SPI

i hope this thing works
my super cheap shit board with the following buzzwords
linuxcnc remora raspberrypi stm32 blackpill w5500 ethernet ........ shield


 

it could but i dont know if it would work

SPI via RPI or ethernet w5500

I can make the thread work but nothing with data transfer, the h743 configuration seems to be more difficult than the F407, I am not able to exchange data.

I would check with some of the grblhal repos as reference, I think there is an H7 implementation. The H7 does look significantly more complicated than the F407.

I do hope you share your repo when your done.

looks promissing, will wait for the real, i will build those to change my old chinese bob, can we add axis to multiple z axis?i have plant to add my machine with diode laser and plasma cut

for that board specifically I ran out of room for a 4th, but it is more for small desk stuff. made to be cheap , easy and accessible. But yeah I would wait until they arrive and I can test them. Im not an electrical engineer and Im not too good with computers, so I expect several revisions.

I do have 2 other boards should arrive here by next week, you might be more interested in the other one. It is a DB25 RPi/Ethernet board, similar to the other one. 

 

I also made an ethernet adapter for BTT/3d printer boards. They almost have a standard wifi socket that can be used for ethernet

the one with db25 port looks good, just need plug and play..greath wait for real test

Hello - first post in Linuxcnc forum!   I'm very interested in this Remora stuff and ended up here via the millennium machines discord as I'm following their progress.  I have a noob question- is there a way to use an older RPi3 with a remora based system ?  Are there any sites/links where I could go to read more about it ?  Thanks.

Hi Lewis,

The original SPI version of Remora was actually developed on a RPi 3B, so yes it can be made to work as long as you can get LinuxCNC installed.
