LinuxCNC + Orange Pi (allwincnc)

Been following this thread for a while now and been having a play around with a Opi PC, originally I tried a OPi One but that was DOA.

After looking at the OPi schematics I noticed that the majority of the camera connector pins are connected to port E (PE0 - PE15), 2 are connected to port G (PG11 & PG 13) and one to port a (PA17). So that would give an extra 19 pins.

Has anyone tried this yet ?



I've ordered a cable & connector on a breakout board to give it a go, but waiting delivery. Whilst I could probe the pins age is catching up and I don't want to break the SBC.

I got a little sidetracked on my OPi project. Have been using it as I had it set up for the mill but have been playing with my new 3d printer and other projects. I still have intentions of using this with 2 MPG wheels for my lathe. Ordered 2 new MPG wheels to test things out.

Yep I'm looking to use mine with a lathe as well, have a couple of encoders on the way as well as a 2nd MPG.

I have been testing with the BoB I made for my BeagleBone black, I think the way forward if the camera connector is usable is a custom board to plug into the aforementioned board.

I have the H3 board with 2GB's... based on the build a few months ago it would run but choked when a real 3d gcode was loaded. lots of talk about video drivers... has something changed?

Orange Pi Plus 2E ?

The reality of it is is for best performance an x86 platform and MESA is hard to be beat.
That's what I'm using for my mill.

As I had breakout boards I designed for my beagle bone black the OPi looks like a good option for the lathe, as that will be more likely used via the MPGs, threading a taper turning is where I'll see the most use of the full CNC capability.

Remora is great if you are using a 3D printer board, everything is there, but if you intend using a stm32 dev board there is still a lot hardware wise that needs taking into account.
Same as this project, the hardware (level translation) needs to be considered.

The beauty I see in going the MESA route is that you buy a board that is ready to be wired into a system.

If you're into tinkering and have a good basic knowledge of electronics these "side" projects are interesting to get involved in.

I've had no issue with video.....except when running X Axis via an ssh connection.....but that is due to drivers used on the remote machine.

@ cncninja I only have an old Opi with 512MB of RAM. Boards and time are hard to come by. I expect the situation to be different 6-12 months from now.

@ ALittleOffTheRails yeah many of us have thousands or tens of thousands in tooling. A few hundred $ extra for Mesa is not a problem. This project like some others using very low budget hardware are for those applications where they might have a few hundred total or so in the machine and tooling. They might be exploring how to move more smoothly using LCNC after running their *duinos for a while.
