Remora - ethernet NVEM / EC300 / EC500 cnc board

Thanks Scott, I got it to work with:
net coolant-flood iocontrol.0.coolant-flood remora.output.6
net coolant-mist iocontrol.0.coolant-mist remora.output.7

Now I need to figure out inputs and spindle.

Mine is STM32 based.

I would have to un-wire the board to be able to remove the lid, but I could take a picture if you think it could help

Hello. How do I invert the 0-10V output for the spindle? when stopped I have 10V and at maximum revolutions it is 0V. or will someone provide a hall for the spindle? I use linuxcnc 2.8.2 and NVEM V2. Well thank you

There seems to be a few versions of the STM32 based NVEM v2, especially when it comes to the output circuit for the analogue 0-10v.

There is an example hal using lincurve to invert the output. You will need to adapt the scale and lincurve parameters appropriately.

When you say that the output is always 10v, is this the case when LinuxCNC is not talking with the board? I'm suspicious that your board might have a different circuit and IO pin than the board I used for development. A photo might help but a real pain with the NVEM not having plug headers.

So far this is my working HAL on EC500 V5.
