Remora - ethernet NVEM / EC300 / EC500 cnc board

Every so slowly getting Remora-NVEM to a point to be able to release 1.0-rc. Good news is that the work to get step rate doubling working has been successful. This will roll into the main Remora code but it's currently running on the NVEM board. I needed to get this running as the slower clock rate on the STM32F207 and running 6 step generators was reducing the achievable step rate. Some fine tuning and we should be able to get 40 - 50kHz step rate on all 6 step generators simultaneously.

 
 

so is it possible to add the pendant to my setup using the skr 1.4 board of old?
If it will work i will order one of these.
The work you are doing is amazing.

Hmm, I don't think it would be impossible but would need some work. You would also need a TTL UART to RS232 adaptor to drive the NVMPG serial connection.

okay so to run the pendant i would need to buy something like this?

and this is the correct pendant?

I dont need to buy it but sometime in the future it would be cool to not have to use a keyboard or map a gamepad.

Yes, these are the hardware required.

For Remora we'd need to adapt the new NVMPG LinuxCNC component to use SPI and modify the Remora module on the controller board side. Maybe something I look at once the Remora-NVEM and Remora-W5500 ethernet versions are up and going.

would it be better to drive it from the pi?

Thinking out loud if it runs on a board this still allows someone to use the ethernet route with a full pc and still have the pendant correct?
