Remora - ethernet NVEM / EC300 / EC500 cnc board

beauxnez, its probably going to be easier to setup qtplasmac first with the installer thing, then add remora to your qtplasmac config, instead of the other way around

Hello, I would like to add to this last topic about height control and the use of a QDC module or ENC software for the EC500 and EC300 boards, which, as I mentioned previously, the optocouplers that have the inputs on these boards do not allow the use of an encoder directly because they are too slow and lose pulses and the QDC module loses counting, so the hardware would have to be modified. I have made a design for a board to connect up to 4 encoders. I leave you the schematic and a 3D image of the encoder. of the board, obviously we would have to have the ENC_BOARD manufactured and that has an added cost, it would be great to find optocouplers fast enough that share the same footprint as the L246 used in the EC500/EC300 boards, I have not found them but if anyone has Anyone in mind to report, I have used RJ45 connectors thinking about crimping the same cable that the encoders of my motors have, however feel free to give ideas in this regard, the spaces located within the 4 DIPs are two 24->5V regulators/ 24->3V3 that I had before and will be assembled later, later I will see how I can share the project through EasyEDA or the *.json files on Github greetings

I launch stepconf I name my machine remora-nvem then I replace my .ini and .hall file with the one remora?

you mean it's better for me to go with an NVEM card?

Hello Beauxnez, I have never experimented with an NVEM board, I don't know what optocouplers that board uses, but I imagine the same thing happens with the NVEM board as the EC300 and EC500 boards, what I wanted to say before is that to use the QDC module the first thing would be to obtain A B and Index clean signals and for that it is necessary to introduce some separate hardware, in my previous tests I have documented the problem and since I have solved it with an ADUM1200 digital isolator, of course this solution is only for testing, we would have to make all this more robust, that is a separate connection board for the encoders, I leave you the post where I referred to the topic, problem and solution,  greetings

@rbobey1989, how fast can the ec500 optocouplers handle do you reckon? Say a 100pr quadratic encoder. Spindle at 3000rpm
