Thank you I got it working. Today I attempted to probe a top left outside corner and noticed that when the routine went to probe the "Y" side the probe does not move over enough to the positive X to probe the material.  It does like it should when it probes the X.  It does the same on all outside corners.  It probes the center position just fine.  I attached a pic of the probe start position and where it fails to move over enough. Any ides on what to look for?

I'll try to have a look at the '9D' branch later. Thanks.

which I got not much feedback..


Just as a word of caution from my own experience:
You mustn't expect to much from a forum thread like this. Few people will even read a post that long, fewer still look at the code and hardly anybody will even try to understand it. I know of at least one long time contributor, since retired, who got quite bitter about trying to get sustained and involved feedback here. Even from the very people asking for the specific feature.

I will do it because I want to, don't need cheering up much, although it is nice, it is more about doing something that I can share with everyone, and we are all roughly on the same page, as to what has to be done, but I will do it regardless, and then it can stay in a fork, or merged, we will see...

Does mesaflash see the card ?
Usually in these situations it is help to attach your ini & hal files and the error reports from when Linuxcnc fails.

I am not sure I understand your question?
This is my last attempt to make it work after having spend days trying to figure out how to configure Linuxcnc to work with my Mesa 7i97T.

So far it has been a nightmare -expensive in time and money.

I opened another thread and have them posted there.

I was wondering if someone could take a look at my hal and ini files and tell me why i have not encoder count on my halshow but the at speed light is green.  All of this worked in uccnc before i switched over.  I set the encoder to 1024 ppr.  I have 5volts going to encoder.

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 

Note than many ethercat drives are also limited to 1khz in position mode. lichuan is, stepperonline/jss i think is and Im pretty sure the delta b3 is. My omrons I think are restricted to 2khz in csp mode.

For 4khz or 8khz usually you are restricted to other modes. At least in the drives I have. There definitely are (much) faster ones, but they are more specialised gear vs generic milling cnc applications.

Point being, 250us sounds great, but I don't know it needs to be any sort of priority cause only few people could use it. But then maybe those few people are important (like the people I know wanting to nanometer scale optical things and MUST have the higher "loop" speed so can't entertain linuxcnc right now)

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!

ciao
Roberto

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?

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
