I still dont have repetier running, but i took the plunge and bought simplify3d and it's working on 115200.  So, i think that's the right baud rate and this is the right answer.

Presumably `lsusb` shows the printer (as it would be the same as `dmesg`)? Maybe try [`usb-devices`](https://linux.die.net/man/1/usb-devices), I *think* it gives you the speed. See [command to determine ports of a device (like /dev/ttyUSB0)](https://unix.stackexchange.com/questions/144029/command-to-determine-ports-of-a-device-like-dev-ttyusb0). If this works, I can turn the comment into an answer

Can you edit your question (not in comments) and post the full output for `dmesg`, `lsusb` and `usb-devices`? I'm most interested in the output of `usb-devices`. Maybe `usbview`?

Hmmm, so it is FTDI and not a troublesome CH340(G). Interesting. I guess that you've double checked that this the board, by disconnecting the printer, running the commands, and then connecting the printer and runningthe commands again, to compare the difference. Also, it seems that the speed isn't given after all... I was hoping that `Spd` was speed, but yours shows `12`. It isn't clear what `Spd` signifies.

Baud rate for Ender 3 on Repetier Host (Debian)

# Baud rate for Ender 3 on Repetier Host (Debian)

(Asked by: username_0 on 2019-08-23)

Trying to set up Repetier host for Ender 3 on Debian.
The /dev/ttyUSBx is found via dmesg, this value goes in config -> printer settings -> port.
Printer connects fine, but commands do not send. Status reads 
xx commands waiting.

I have tried all the various baud rate settings <= 250k to no avail. 
Is there something else I should be trying, or what is the correct baud rate to set?

Your firmware configuration may vary (probably worth checking what you have set), but from [The Ender 3 configuration is set to 115200 baud rate #12174](https://github.com/MarlinFirmware/Marlin/issues/12174), the standard baud rate seems to be 115200.

> I think the default Ender 3 configuration is aligned to the Ender3 official confg, which has 115200 so...

Ah, but this is Marlin, and you're using Repetier. Hmmm, maybe ignore that then.

According to [Recommended baud rate?](https://forum.repetier.com/discussion/1455/recommended-baud-rate):

> Normally 115200 or 250000 baud should work find and usb->serial latency is the bottleneck.

Apart from that I don't know. Sorry. I might delete this answer, if it doesn't help.
