Remora - ethernet NVEM / EC300 / EC500 cnc board

Has anybody got these working on a lathe with index and threading working correctly?

i think, encoder with index-pin will not work

I had a test working with the spi variant of remora.
I used the 3d printer main board that has support for hardware encoder input.
I coupled it with an axis to test rigid taping on my mill and it worked.

Hi Fintech, what's your proposed setup? Encoder + Index input?

Current firmware does not have an encoder module because of the static config. I'm still working on getting the C++ version of the code working on the RT1052, which would allow for dynamic configuration. Like for the RP2040 which I've just got working.

In the meantime, it would be possible to create a special static config firmware version with software encoder on a couple of pins.

I was thinking something simple like one HAL sensor like I have it setup in mach3. One pulse per revolution. I know this not a good solutions in case the RPM drops under load. I've seen some setups with Dual HAL sensors.

Should be possible then with the current firmware.
