Remora - ethernet NVEM / EC300 / EC500 cnc board

Hi Scott,

Question about the NV-MPG. Do I need to compile the  nvmpg.c  and install it in to linuxCNC? I see the HAL file for the NV-MPG. I got 5 axis working on EC500 V5. Probe_basic is up and running. I have 3 devices to play with, NVEM V2, EC300 V3, and EC500 V5. Probe_basic lathe looks pretty cool. 

Yes, you will need to install this component with halcompile.

Hi Fintech,

Just looking at one of your videos and you have the same NVEM version that dec077 has. Did you get the analogue out working ok?

That one is currently running mach3 in my CNC router. My NVEM was the first one I started playing with. The original idea was to put my EC500 V5 into my router with mach3. Use the NVEM to play with LinuxCNC. My messed up EC500 V5 forced me to sit down and learn LinuxCNC. The more I play with LinuxCNC the more I like it. I'm pretty close to pulling the trigger.

Hello, I need your help!
I am trying to play with LinuxCNC on my EC500, but not success. I follow these steps:
1. Flash Firmware with Pyocd=> Successed
2. Install the lastest LinuxCNC on my PC, then do halcompile the "remora-nv.c" => OK
3. Set the PC ip to: 10.10.10.10, netmask set to 8, Gateway set to 10.10.10.1 then try to ping IP with good respond.
4. Copy the basic config from Scotta to Linux config folder.
5. Run LinuxCNC fine !
==> But no lucky that the LinuxCNC always at ESTOP state so I cant do anything with it. Try to use NO switch as Emergency button, connect one wire to COM- Pin, another wire to IN02 then test for sure but nothing.
I go through page to page to find out anyone have the same problem but till no luck, as Scotta said seem my board have not successfully connected to PC. 
Please help me how to check where the problem come from, correct me if I wrong, Thank all guy.

P/s some picture of my state if you need some more clearly info.

10.10.10.10 is the ip address hardcoded in the firmware, you should set the ip address of your pc on the same subnet but with a different ip, i.e. 10.10.10.2. If I'm not mistaken, the netmask is /24 instead of /8; you don't need to set a gateway.

As things are now, at best you are pinging yourself on the pc network interface instead of the ec500 card, at worst there is an ip conflict on the subnet: it's not surprising LinuxCNC does not want to come out of the estop state as it's not really communicating with the card.
