Wirering raspbery pi 3 (bcnc) to arduino (grbl)

[bjao1]

I loaded bcnc to raspberry pi3 & grbl to arduino uno. connected them using usb cable Problem is: I can not get them to communicate. The serial port is not available in bcnc. Do I connect the tx-rx pins of both boards? Please help Thanks

[lalo-uy]

NO, since you conected them with USB cable, in bCNC look for USB serial ports like /dev/ttyUSB0 may be a raspberry user have no access to them, try "sudo bCNC"

On my Pis, those ports hve Names like /dev/ACM0 or /dev/AMA0. Look for those.

[bjao1]

I installed the bCNC image from http://wiki.protoneer.co.nz/Raspberry_Pi_CNC_User_Interface_SD_Card_Image Using file manager, I see the dev/AMAO file, but in bCNC the only option under connection icon is Hard Reset. I run the RPi3 Serial config according to the instructions. Still no serial port. I am new to Raspberry pi and Linux, so please bear with me. Thanks for your help

[Protoneer]

The serial config in the instructions are related to the hardware serial and should not effect USB devices.

Might be worth trying to connect to your USB device via a terminal app like Minicom. On 21/05/2016 3:57 am, "bjao1" notifications@github.com wrote:

Yes, I used minicom and it still could not fine a serial port

[bjao1]

Can I connect the tx-rx pins of both boards to make it work?I just want them to communicate so I can wire the arduino uno grbl to my stepper driver Thanks for your helpRobert

Raspberry Pi is a 3V device and Arduino UNO is 5V device, you may damage the Raspberry

if this is the way to go, I can make the txd & rxd pass through a voltage translator. how is your setup with bCNC RPi3 and grbl arduino uno? I mean how are they connected? Thanks

[ghost]

I use a RPi2 and RPi3 with USB to grbl with no problems. You may have to setup your user as a member of the dialout group.

Assuming you are using the default login then for user pi:

sudo usermod -a -G dialout pi

[bjao1]

Hi nfz I tried your suggestion, still not change (can not communicate with arduino grbl Are you using bCNC image from protoneer wiki site? If not can you share what bCNC you are using? Thanks

[ghost]

I should have mentioned you would probably have to reboot your pi after issuing the usermod command as it would not take effect until the next time you logged in.

I use bCNC from this github, usually do a daily git pull to stay up to date with the latest changes.

Also make sure pyserial is installed but if you are using the protoneer's image then that should already be setup.

To make sure that the arduino board is actually powering up when you plug in the USB cable, do lsusb before plugging the board into the RPi3 and then after. List the results here. lsusb will list all the active USB devices plugged into your RPi3.

Then do: dmesg after you have plugged the arduino into the RPi3. We are only interested in the last 5 lines and list those here. dmesg will list all device messages in the kernel ring buffer and we are interested in the device messages for the USB driver that gets setup when the arduino gets plugged into the RPi3.

Here are the last few lines of dmesg output on my RPi3 after I plug in the arduino board running grbl:

[lalo-uy]

can you post the result of diss comand in the PI:

ls -l /dev

Looks like your arduino board is using a HL-340 USB serial chip and its connected to /dev/ttyUSB0 and belongs to the dialout group. You should be able to connect. You may have to type in /dev/ttyUSB0 in the Port setting although the drop down list should show it.

After changing the port you will have to left click on the open icon to the right.

HI NFZ A million thanks for your help! It is ALIVE!!!!!

Now the real fun begins.
