I’ve installed bCNC on RaspberyPI3 as follows:

RP3 running Python 2.7.13

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update
sudo apt-get install python-tk
sudo apt-get install python-serial
Downloaded bCNC from github
Extracted bCNC to my RP3 Desktop
cd bCNC
sudo python bCNC

bCNC opens, but I can’t connect with available ports.

Possablity I missed a package to install?
Maybe I need to manually type in a different port?

Attached are screenshots of what I’m seeing in bCNC

Baud: 115200
Controller: Grbl

Any thoughts?

Do you have tkinter installed?

3

Type and paste here the output from:
ls -l /dev

4

Have you tried running bCNC with sudo? Its possible that without being root you do not have access to the serial ports.

5

tkinter can be installs under the name python-tk (tkinter not available with apt-get)

6

sudo from terminal doesn’t seem to change behavior.

Here is the output from ls | /dev:

Try /dev/serial or /dev/serial1 as your port.

This may, or may not help, but I found this link to a prebuilt Raspberry Pi image that has bCNC (and others) all ready loaded.

https://wiki.protoneer.co.nz/Raspberry_Pi_CNC_-_Quick_Start_Guide#Download_the_pre-configured_Raspberry_Pi_image

10

Found the source of the problem - my E-Stop switch. Leaving it unplugged for now and bCNC shows “Connected”.

11

Guess its never easy - went to Control and tried to jog X-Y-Z independly, I get an “error:9”.

I am assuming you have not installed Python? Can you start a new thread?
