Remora - Rpi Software Stepping Using External Microcontroller via SPI

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.

my super cheap shit board with the following buzzwords
linuxcnc remora raspberrypi stm32 blackpill w5500 ethernet ........ shield

 

 

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
