Hi everyone,

As promised in my last update, I’ve just released the v1.0-eval package, including the driver, the Arduino firmware, and full documentation.

I’ve set up a dedicated project page to host the quick-start guide and the wiring diagrams to make the setup as easy as possible.

What’s included in this release:

HAL Driver: The core engine to interface your USB panel with LinuxCNC.

Evaluation Firmware: Ready to be flashed on your Arduino Uno.

Technical Docs: Wiring schemes and HAL configuration examples.

You can find everything here: Project Home & Documentation: bobwolfrst.github.io/io_decoder-linuxCNC/demo_mode.en

Quick Links:

Direct Download (.zip):
github.com/bobwolfrst/io_decoder-linuxCN..._decoder_eval-v1.zip

Technical Demo: Evaluation Mode & HAL Test Video (showing the real-time response of the physical buttons and MPG in HAL).

I’ve also recorded a short technical demo showing the driver in action: you can see the real-time response of the physical buttons and MPG selector mirrored instantly in the HAL pins.


I’m really interested in your feedback regarding the setup process and the latency you experience on your machines. Let’s break the "USB dogma" together!

From what I can see, different modes can live side by side in the cia402 component without problem.
They already do today. Different pins, yes. For example PV needs two accelerations and a speed pin.
Homing, probing etc their own set of pins. And possibly some small piece of logic, like "at-speed" indication.
And then handle the switching of modes with the position feedback, a bit optimistic this can be done in a general way.

Thanks for the reply! I’ve done all that so I believe my G2 is optimized for LinuxCNC.

However I’m a bit limited by the low ram (8GB), low disk space and etc.
 

This is nonsense! 4 gb RAM is fine for LinuxCNC but it will tolerate 8gb without ill affect. Linux is more memory efficient than Windows.....

What program does not recognize the card?

The ip is 10.10.10.10
I can ping it.

I just "finished" converting an Axiom AR8 Elite from RichAuto controls to LinuxCNC. I have quite a few details left to tidy up, but it's working.

Configuration and wiring notes are on GitHub , and I made a YouTube video out of the project.

I'd appreciate anyone pointing out stupid mistakes I made.

What IP address is selected on the 7I97T?

What does the command:

ip a

return?

 

Hi 
Coming from my safe world of Mach 3 and 4 I have now made the jump into Linuxcnc. 
OMG its complicated!
I have spend almost a week trying to set up Linuxcnc 2.9.4 (and a couple of other versions) on the mesa 7i97T card. 
Is there anybody out there who has made this work?
I can make it ping but thats as far as I can get. From here there is only "board not found"

Is there any known challenges in this setup and will it ever work?

Best regards

Nicolaj Hvid

I tested the signals on the rotary control.
The pins for feed.selected light up depending on the selection.
whb.halui.feed-override.scale always remains 0.
whb.halui.max-velocity.value always remains 166.666. 
 

    Use this xml file instead. There are all the ios configured.
Also you have to program on each drive the following:
P2-18 -> 0x0130
P2-19 -> 0x0131
P2-20 -> 0x0132
P2-21 -> 0x0133
P2-22 -> 0x0134
P4-06 -> 0x0000
Or use the attached parameter file if you have the asda-soft.
Rename the *.txt file to *.par

Rod asked you to post the result ofin a terminal.

also i have issues accessing the analog and spindle part, don't know if it is linked to the framework or something else.

I don't think I've lost the network.
I've selected the pci card to connect to my network (in fact, I can normally access internet).
BTW, this evening (here's almost 6 pm) I hope to make another try (if my wife allow me  )

Sounds all sensible to me but I really don't feel competent to comment on the proposed path.
I certainly like the structured approach of your initiative, that is something that has been sorely lacking in other attempts.
I think/hope that Rob will be able to give an educated opinion on it and shape it into a concrete roadmap.

Note that Mitsubishi SSCNET requires a servo cycle <= 222us

defenetly is great to have something faster then 1ms .. ethercat can run at 50us with 16axis but this complex calculations are far slower for now 

I think 250us is very pretty goal (common industrial standard) at any hardware and then reduce it based at used hardware 

HAL file (with @andypugh suggestion) attached, as well as current ini file
