Fluid NC - WiFi Problems with ESP32

Hello,

I'm having trouble connecting an ESP32 running FluidNC to my home Wi-Fi network.

I'm currently building a custom CNC machine and wanted to test whether FluidNC runs smoothly and to take a look at the web UI. The problem is that I can't get it to connect to my Wi-Fi because the SSID contains an exclamation mark - it's just the default FRITZ!Box network name.

I can't realistically rename the Wi-Fi network because I would have to reconnect a huge number of IoT devices afterward.

Here is what I tried so far:

- Setting the Wi-Fi credentials through the web/UI config: the exclamation mark disappears after saving the config.

- Setting it through the terminal: either the "!" triggers terminal behavior or I have to escape it using "%21", which also doesn't work.

At this point I'm getting pretty frustrated.

AI suggested editing the config directly, but from what I understand, "config.yaml" is mainly for hardware configuration like motor definitions, pin mappings, etc., not Wi-Fi settings.

Does anyone know how to properly use an SSID with "!" in FluidNC?

PCB Review: CAN Transceiver

Hello, this is my first PCB ever I'm actually going to order, and overall one of my first pcbs. I already asked the AI to rule out some dumb beginner mistakes, which it did by the way. Now I wanna hear what the experts have to say.

The PCB was designed in KiCAD and is intended to be used with other pcbs. I used horizontal header Pins, so you can plug this into other pcbs, then screw it in like a M2 SSD.

I attached the Schematic and PCB Layout.

I would be really thankful if someone could review my work (also electrically).

Btw, is 40€ shipping from JLCPCB to Germany normal? I selected Global Standard Direct Line, and it said 8€ or something like that. But at checkout, the total was 40€, although the item price was only 10€.

Thanks!

Hello, does the esp32-p4 have good rust support like all other chips? I read some blogs/watched some videos saying they wrote their program for the P4 in rust, but I don't see it listed under supported chips on the ESP HAL GitHub Page. Does somebody have experiences with rust on the P4? Does MIPI DSI and CSI work? Is there a Stepper motor library by any chance? Is there a servo library?

For Context: This would be my first embedded rust project, and one of my first overall big rust projects.

I would probably need to use the library with the std support, because it's easier right?

Thanks in advance.
