Remora - ethernet NVEM / EC300 / EC500 cnc board

Hi, what we've learnt is that there seems to be no difference in hardware between the boards. They are limiting the number of axes in software. Great news is that Remora allows a "3 axis" board to have all 6 axes available.

Currently the firmware has the IO and analogue out working. I'm trying to get the C++ version of the firmware running on the board which would then allow the inputs to be configured for other functions like encoders (software counting). There is an existing Remora encoder module for the 3D printer boards which should just drop into the code once I figure out the Ethernet issues in the C++ version.

Hi guys, I just wanted to tell you that I have received my CH32V307-EVT board, these past few days I have been looking at some openWCH examples in their official github repository and I have seen that they use a non-opensource library for network control (WCHNET) , from Scott's previous developments I have seen that he uses (LWIP), I have also searched for information on how to port LWIP to WCH MCUs specifically to CH32V307 and mmmmmmm, I have not found much, although it would not be very difficult to do it through WCHNET since there are examples even for IAP, Scott if you have any thoughts on this on the way forward you would be welcome.

My CH32V307-EVT board also arrived on Friday. I haven't started to play with it yet.

Hmm, what are the rules about using closed source code in an open source project...?

Looks like someone has started a LWIP implementation.

WCH looks to be sharing a LWIP example to members in their online forum. I've had no luck registering (with the help of Google Translate).

Any native Chinese LinuxCNC forum members willing to see if you could obtain a copy??

I have managed to register in the forum www.wch.cn/bbs with the help of google translate and I have asked for a portability of LWIP without an operating system, from what I have read they usually respond by email, so let's wait for an answer.

你好 是要下载这个文件吗？
