Remora - ethernet NVEM / EC300 / EC500 cnc board

Hi Scotta,
Were the master branch implement C Axis? I tried XYZABC configuration and saw C Axis pulse/dir were not there.

Opps, yes there is an error in the master branch, line 259 in main.cpp. Looks like a hang over from testing. Not to worry. I'm going to merge the develop branch into main hopefully today. This will make using the configuration file the standard way to set-up the NVEM.

For those monitoring the dev branch, I've pushed a new update that includes a default configuration. This implementation presents 3 joint stepgens and no IO so that people can know the board is up and running when first set-up. Alternatively this could be a full config if people would think this is more appropriate. The intention is to merge dev into main and create a release now that bugs have been resolved.

Remora-NVEM 1.0.0 has been released. Thanks to everyone for testing and helping with the beta bug fixes.

github.com/scottalford75/Remora-NVEM/releases/tag/1.0.0

For those not wanting to worry about the source, the bin file is  github.com/scottalford75/Remora-NVEM/tree/1.0.0/Firmware

I have received another NVEM board (I killed the PWM output on the test board) and will use this to make some short YouTube videos on how to flash the firmware and get LinuxCNC up and running with the board.

I'd like to step through the LinuxCNC configuration setup (ini and hal) for the different features such as setting up and e-stop, end stops, spindle etc. If you have a running config for some of these, please share them here so we can consolidate into a working example to help people get up and running.

For those want to run B and C Axis.
Not sure if all NVEM V2 are the same in pul/dir pins, for my PCB,  B and C Axis as following:
 B step: PE_7 
 B dir: PE_6
C step PE_5
C dir  PE_4
I downloaded this config and all XYZABC were running fine.
 

Scott,

Spi vs Ethernet.
I have a Ethernet module that I could connect to my 3d printer main boards. Any advantage vs using spi?

The main one I can think of is the com is less sensitive to interference. And not limited to devices with spi support.
Any other reasons?
