Reading data from Arduino

Hi everybody,

I was wondering if it is possible to send the gcode from Arduino to Linuxcnc?

For example, can I send the gcode via Bluetooth to Arduino and then this will be read by Linuxcnc?

Can someone help me?

Thank you very much

Currently - definetly not.

What purpose of such kind of work Bluetooth > Arduino > linuxcnc?
Why not Bluetooth > Linuxcnc for example?

You might like to connect your Linuxcnc to the network and use axis-remote
Or just transfer files using the Operating system tools.

I was thinking that It would be simpler to connect bluetooth to Arduino.
However, if it is possible to connect it to Linuxcnc, it would be perfect!

Any suggestions?

Your main deal is to load G-code by Bluetooth or you need to remotly load G-code to PC by any way?
As was written above by Rodw, you can use possibilities of OS to load file to needed folder and then to open it in linuxcnc

Yes, my purpose is to load G-code by Bluetooth. I would prefer not to use the OS tools because the machine is thought to be portable, that's why I was thinking of using Arduino.

So, the plan is Bluetooth onto Arduino RAM (is it big enough?) and then to LinuxCNC (USB? Serial?)

I guess if the Arduino was configured to look like a USB drive that might work quite neatly.

An ESP32 dev board might work better, then there is the option to use WiFi too. I have found it easy to make simple web front-ends for ESP32 too.

Seems to suggest that looking like a USB Flash drive is not possible for ESP32 (and probably not for Arduino either)

I am not clear what you mean by "thought to be portable".

Let me explain: I have a touch probe connected to a robotic arm to scan the surfaces of bodies. My purpose is to send my data from LinuxCNC to another PC via Bluetooth to make this task more real time.

I have a non-motorised version of the same idea, an old Faro Arm.
(It's a stalled project, I got stuck trying to work out the D-H parameters of the arm in a format that a serial kinematics module from the internet understood)

If you want to send commands to LinuxCNC then linuxcncrsh might help:
linuxcnc.org/docs/2.8/html/man/man1/linuxcncrsh.1.html

It seems that, as long as you can get the bluetooth connection to look like a port, it should work.
