GrblHAL with Ethernet connectivity

[cheechNC]

Wondering if this board NUCLEO-F756ZG has been used with ioSender with Ethernet. I tried the WebBuilder for STM32F7xx but the connection combo box does not have an ethernet option. Surely Im missing something.

A board like this looks most interesting as it has ethernet and is apparently compatible with existing break out boards/ shields designed for the arduino Uno.

There are board maps for the Protoneer and the Uno but I have not enabled them in the Web Builder yet.
Ethernet cannot be enabled since D11 (Z-limit) is used by the ethernet hardware. Another pin could be used instead - but which? D0 and D1 (UART RX/TX) are candidates, and A4 and A5 are too? And it has to be documented somehow...

Ideas?

thanks for quick reply. Sorry not up to speed with these things. Only been looking for alternatives a bit and stumbled upon this.
The hat that I have and Like is this https://www.yrcnc.com/

I have now added Uno and Protoneer board maps to the Web Builder, and enabled ethernet for all builds.
Note that the F756 is a 3.3V device - you may have to modify the breakout board to avoid damaging it.

The yrcnc board is a better board since it has optocoupled inputs, there is also a buffer on the board unlike the Uno/Protoneer boards.
I have sent a message to yrcnc requesting information about the board, preferably the schematic.

Since the D11 pin is used by the Ethernet hardware I had to modify the board maps depending on the configuration, see the map files or use the $pins command to check the pin allocation.

Thanks @terjeio! I will get a F756 and try. Yeah that little b.o.b. was a wowzer back when I "stumbled" upon it. 2018 I think it was. All I have is the available manual PDF. The creator was Leuben Hristov. I really hope they are around and reply. He may be on Linkedin.

I wonder if it would be possible to have 4 axis off of the F756Nucleo? are there enough pins? a silly though is that I don't need the XYZ individual homming/limits input.. I normally loop my switches NC and use one input for XYZ homming;
Another thing for me would be M3 and M4 outputs. Perhaps a way to use Mist or Cool as M4. But not super important as I can trick the post processor to do that.

Ethernet is a must;

I have not yet heard back from yrcnc.

I am not any longer due to their sloppy handling of user data (email, password, ...).
If you can get hold of the schematic then that would be nice.

There are plenty of pins - most not broken out to the shield. The shield may support four axes already if it is based on the Uno or Protoneer map.

See the board maps for the Uno and/or the Protoneer for pin assignments.
