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.

Oh yeah I fully get that.
I have a foot in both camps.

I really like this Opi Project.

If Linuxcnc supported the PRUSS on the BBB I'd be using it.

It does, Machinkit was an SBC fork of LCNC and is still used on PocketNC 5 axis desktops their new control is BBB based on LCNC and with full 5 axis tool center point control. I'm hoping they will release the code per LCNC lic

Although it was based on Linuxcnc MK development has taken a different path than mainline Linuxcnc. There has been a lot of lowlevel changes made as well.
Machinekit development has been broken it 2 code bases, machinekit-hal & machinekit-cnc. There is also support for web-based interfaces & control, along with machine-talk which is a kind of sever-client model.

I have used Machinekit on the BBB, but switched to Linuxcnc for various resaons.

could you give me these reasons, just out of curiosity, i have never used machinekit but i have heard a lot about it and i would like to know why it has returned to the official linux CNC
