Remora - ethernet NVEM / EC300 / EC500 cnc board

Not sure if understood the question but...

The firmware for an STM32 NVEM is different to a RT-1052 NVEM.
But once flashed & working the pinouts should be the same (with the exception of OUT1 & OUT2 which are reversed in the RT-1052 NVEM)

If you need to flash a STM32 NVEM I suggest you follow Scotts original video. Upload the correct config for your use.

If you need to flash a RT-1052 NVEM i suggest you use the pyOCD method. (Look about 3 pages back)

Once you can ping the boards setup a test config & start using halshow & look at the I/O ping under remora in the tree.

Hope this helps
Alex

Douuu,
i successfuly reprogrammed the stlink clone with the dap firmware,
Installed Python and pyocd, connected to the RT-1052 nvem and power it on. Try to read or reprogramming fw..
No response at all..
​​​​​​the stlink dapped didn't blink.. solid blu led..

What can i check??

Sorry for the previus post.. i made it works.. programmed back the stlink with the original st-link fw, programmed as dap the first st-link and bingo.. it works..
Already tried the remora fw and flash back the ec300 fw in the repo.. it works also better then before.. the limits error gone away...
I roll back to linux cnc and try well..
Did you think re remora work well with the mks closed loop driver??

Bye Matteo

Great news Matteo! Just need to keep you using LinuxCNC

Yes, already flashed again with remora.. and now i test on bench.. it's quite different linuxcnc from mach3 and i need to study a lot thanks again for your great works

Hi Scott

Could I get you to check this
I am running an NVEM RT-1052, when I activate remora.output.00 OUT-2 comes on.
And vice versa. remora.output.01 turns OUT-1.

This seems to be backwards. Is this whats intended?

Thanks
Alex

Hi Alex, I confirmed the IO on the EC300 and it is correct. So there is a slight difference between the NVEM and EC300. I have updated the source and created individual firmware versions for the NVEM and EC300. Can you please test the NVEM version?
