Remora - ethernet NVEM / EC300 / EC500 cnc board

As far as I know , only quadratic encoders are currently supported with remora and rt1052

I'm not sure about the ec300 but the ec500 has the ability for hardware counting but you have to bypass the optocouplers as they are shite. 

Thank you both,

Andy, I was meaning using the remora encoder module, but I appear to have misread/missed the part where it would not support count mode like the LinuxCnc one. I will have to stick with the LinuxCNC one, which is working, but only up to around 1900 rpm on one of the RPi pins. likely a base period issue.

Murphy, thank you, that is unfortunate that the 500 is needed for hardware. I don't mind bypassing the opto's or replacing with a faster digital equivalent even if external to the 500. but all that can wait until I sort out a quad encoder of some description.

You will have to confirm , ec300 may still hardware count by modding the same way the ec500 is done. It also has the rt1052 ic ?? 

Yeah the EC300 is the rt1052. Its become a slightly null point for the moment as I've managed to fix the issue temporarily. the pull up on the schmitt trigger for the opto interrupter sensor was too high off the shelf (cheapo Chinese modules) so the pulse width was way too wide, so above around 1800rpm it was just giving a logic high instead of pulses. now got a nice pulse train up until around 4500rpm so for now, i think this will work.

Anyone else able to get a spindle encoder working In CSS mode with the RT1052?

Hi Murphy
No but I will start my lathe project as soon as the mill is done. Was it you that posted a picture of the octocoupler bypass, I wanna try rigid tapping with the mill but I can't find the picture of the board modification.
