willing to give this away for free now

now offering this Free to a keen linuxcnc developer

i did try to reload parameters but the PLC board does not boot, could be as simple as a voltage issue on the PCB.. i dont have the time to fix it, but i am willing to let this go to a good home and more so to someone who can use it develope linuxcnc to such a machine and give back to the community

i can load to transport,
can give away a magazine bar feed with machine also that will need interfacing (LNS BRand)

I am working through retroftting a motionmaster. I kept all my relays. My goal was slightly different, I wanted to keep the wiring as stock as possible because there was a chance of the whole upgrade not working and I would want to sell it stock, but I think I'm far along enough that its worth more as a linuxcnc box now.

For what it's worth, I contacted Copley Controls sales. They said they couldn't help me on that obsolete model, but provided a datasheet on a similar 4113 model. If it can be proved the pinout matches this might help.

You should be able to build a PREEMPT_RT image using Armbian for the OrangePi and install LinuxCNC and XFCE on it. I have done this with a Odroid N2+. I would go that way and ditch the PC out of the equation.

In the build process, you just need to run menuconfig to configure the PREMPT_RT flags.

Yes running Linuxcnc on the OrangePi would be easier. And the board would probably run it extremely well. But again, that’s normal. 
if I’d opted for the w5500 on the SKR, I’d have to have ported the code over from the stm32/rp2040 side of things. Not hard, but not as challenging as this.
So I opted for this. Means I still have the main pc doing all the hard legwork, and the OrangePi just bridging the traffic over to the SKR. Which I think long term, is the best option, performance wise. This was the SBC isn’t doing a lot of work at all.

the last time I did anything challenging, was when I originally bought up Armbian for the OrangePi 3 LTS. This was nearly 5 years ago, and it’s the same board I’m using today! Never found a use for it! I had it running klipper and a 3d printer for a while 

I wouldn't do this, but I'll follow the topic as I'm sure I'll also learn something. Personally, I would have tried to run LinuxCNC directly on the OrangePi3. Or added a W5500 to the SKR.

A couple of months ago, I did some tests with Remora and a RP2040; I watched Rod's video on Youtube to achieve real time performance on the ethernet connection between a Pi400 and the Pico. My guess is that you'll have to compile a real time kernel for the Armbian OS too (did it last year for a Radxa Zero 3E, worked more or less).

That retrofit seems to use individual drives. The real issue if you want to use
you combined 3 axis drive is to obtain/determine the pinout of the 25 pin interface
connector on your drive (or controller).

Old but still valid:



And some nice tutorials:

Go for it!
Despite Tuxcnc being right about the time and effort, humanity would not reach very far if it did not try stuff that may or may not be "standard".

You can download the support zip file from Mesa's webstore:

(in the specification tab for the product)

Hello pcw,
many thanks for your answer. Where i can get this file, I am looking on the Mesa page and in Github?

If you have a 7I96, it can support up to 4 MPG encoders directly on the isolated inputs
with the right firmware ( 7i96_inmd.bin )
 

Hello everyone,I am new to LinuxCNC and would like some help with the installation process.I would appreciate guidance on:

• The recommended Linux distribution for the latest version of LinuxCNC.
• The installation steps for a fresh system.
• Any prerequisites or dependencies I should install.
• Common installation issues and how to resolve them.
• Whether there are any official installation guides or tutorials for beginners.

Thank you for your assistance!

Well I’m always up for a challenge!
I reckon I can get this running as reliable as ever.
This was the best solution I could think of, as usb isn’t an option. Then realised, this has the potential of actually being quicker and more reliable than usb.

You're wrong.
You will waste a lot of time (that's also money) and you will reach a wall that you can neither get around nor jump over.
Short time ago I have removed four Remora EC500 from working machines, because this project has no future.
I spent many hours with this hardware and not solving some troubles (stupid 3,3V differential outputs not fitting motor drivers and not working spindle encoder).
I bought four Chinese 7i92, because it was cheaper and better, and now I have many time for other projects...
