RaspberryPI, no USB connection to ch341 arduino nano with GRBL

[Geeklab3D]

Hi I followed the installation instructions on the website and installed the latest Raspian on a new Raspberry Pi 3. I also enabled Serial connection in the Raspberry Pi configuration. The webinterface work, except that the connected arduino nano ATmega 341 with GRBL don't show up in the machine connection.

In the Terminal dmesg shows me:

usbcore: registered new interface driver ch341 [ 3.115097] usbserial: USB Serial support registered for ch341-uart [ 3.115186] ch341 1-1.2:1.0: ch341-uart converter detected [ 3.117234] usb 1-1.2: ch341-uart converter now attached to ttyUSB0

....... I installed the Arduino IDE and get full access to the nano. I flashed the latest GRBL Version to the nano and still have no connection.

If I connect my W10 Notebook with Eleksmaker to the nano, everything works normal.

Any idea, why this is not working? Thank you in advance.

Check which version of serial port is installed. Also check develop tools for errors.

Hi everyone,

Any new regarding the issue? I have tried all the combinations above.

I pull the latest and install serial-port 4.0.6 ... no luck I pulled the serialport-6.2.2 branch and install ... also no luck..

I am using serialport@4.0.6. I am also trying to enable debug on the about page.. but the Toggle Devtools button is not there...

[ellisgl]

Use serialport@6.2.2 instead.

[ellisgl]

@vang1804 Did that work for you?

[vang1804]

Yes, it seem to work with 6.2.2 and the main brunch. I didn't have to time to really test it, but seems that it connected to the GRBL.

Can we close this?

I have the same problem. I found a reason and fix https://github.com/LaserWeb/lw.comm-server/issues/91

@filka96 Hi, I#m still running into this problem. Can you clarify how the fix works? Don't have a clue about node.js config and how to apply this. Many thanks

@t-richter2 How did you obtain LaserWeb?

• What platform are you installing lw.comm-server on? A Pi?
• Are you building it from source? if so; where did you get the instructions?

The discussions and solutions above are for people who download the source code and build that using npm/nodeJS. And these issues are now fixed in the latest LW versions. This is a closed issue.

Please start a new issue, and include info about what you downloaded, from where, and what you then did to install.
