Custom Bart Dring FluidNC controller

USB-C is newer, higher current, faster (potentially) and much easier to source the cables. Seems to be better suited to most of V1 design goals to me…

That said, I probably wouldn’t use the USB connectivity much, I would be far more likely to use wifi.

That is the nice thing about the esp32, wifi, bluetooth, or wired (I have not tried wired yet).

I went for it and bought 100 USB-C style. Large test batch. I got the cp2102 style, that should mean easier connectivity if you do use that. Although we do have update from the SD so I suspect some people might never plug them in.

I run my existing 6 pack almost exclusively over wired. The PCB antenna on my ESP is kind of crap so the WiFi is a little slow. With that said I would absolutely favor an external antenna connection on your board.

The ESP is easy to swap for the external version but I think I will stick with internal for at least the first few rounds. That little external antenna seems pretty fragile.

Personally experienced, and think we may have seen a few folks on the forum experience Wifi issues with ESP-01s that use internal PCB antennas that struggled to compete with other Wifi signals.

Another possible benefit of external antenna is that it allows for the controller to be housed in a metal heat sinking/dissipating box, providing external antenna is threaded out a port opening. Would that help reduce/avoid fan requirement?

Looking forward to see external antenna support later on if/when you/someone has time to mod.

The only benefit to USB uB is that I have a bunch of the chargers and cables around. The USBC is in high demand. But each year that goes on, that is less and less of an issue as I keep collecting more usb c cables and chargers.

Mostly worried about the connection. It is very fragile. Anyone that uses a metal box is going to need to mod the external antenna to add length anyway, $7 for the External antenna version. I can easily add it is a option when you check out but That last round of feedback was clear that I had far too many options everyone wanted a clear path, less options.

I am concerned about connection issues but with wifi or bluetooth direct connection should be easy, connecting to your home network is where you might need some extra power but that is not how they are going to ship, and considered “advanced”.

I can’t please every use case so I make sure to make every use case possible even though it is not shipped that way.

Those little MMCX connectors aren’t too bad, in my experience. Main thing is to provide strain relief somewhere nearby. I think their saving grace is that there is very little retention force in them, so it’s very hard to accidentally damage them through manipulating the cable etc.

It’s always something someone can replace themselves relatively cheaply and easily, if needed, in my opinion.

I have a growing pile of Micro B cables from devices where the connector failed. It’s generally not worth me replacing the connector or re-flowing the solder and then staking the connector down with epoxy which is what we used to do to ‘harden’ these connectors when used at work.

I have seen a USB-C connector fail, but it was on a really crappy device with an equally crappy USB-C cable. I didn’t think it was possible to cheap these out like that, but apparently there is no limit to the depths of junk which cheap manufacturers are able to produce.

I’m trying to move my collection of devices over to USB-C, or lightning on the Apple devices- which I would prefer went to USB-C as well.

OHHHHHH Buddy!!! So close now. I hope I wake up to a “shipped” email.

The nice thing about my 6 pack is the functionality with the wifi. I even use the smb1 file server from the router from my wifi access point and have no need to upload files using my pc (but it adds one step to the workflow)

I don’t understand. Without wifi, are you using the USB or bluetooth?
