I do like your thinking!
I have been toying with putting an encoder on the spindle. (I have some spindle encoders that was salvaged off Mori-Seiki lathes in a box somewhere) Using the index marker on those should give an accurate rev counter for the MESA and HAL implementation. I would also have a solid encoder for the spindle, should I want to venture into rigid tapping...:thinking

Considering the Atom N450 is a single core CPU I'm unsure how isolating a core that doesn't exist would work.
You may get better latency if you disable Hyperthreading.
I'm assuming you are going to use the parallel port.

Thanking you kindly sir.

They all count and will be removed.  

Keep it up and you will be banned.

If you mean the GitHub link, no, you don’t need to remove it. It’s not a mirror. It’s your own work and it’s been communicated as such.

That is not the image I'm referring to. That image has been uploaded via one of the mods.
I don't not have access to any of the Linuxcnc resources. Even if I did I would ensure that the image was vetted and approved by others.

Use this ISO

Boot the PC from it and run the tests in Live mode, meaning do not install, see if it hangs.

Literally what I said in my post before it "mysteriously" disappeared into thin air.

(no offense to you)

Sigh...

Inspired by the post of the same name by unknown.

Referring to this: forum.linuxcnc.org/29-forum-announcement...unsanctioned-mirrors

First of all, does <removed> count as a mirror?

It's not a real mirror, it's an A record to the IP of forum.linuxcnc.org in my Cloudflare DNS.

Second of all, I assume <removed> counts and must be removed from posts (bla bla bla) because it's served from Cloudflare Pages from my fork of the LinuxCNC/wlo repo.

Third of all, I assume <removed> totally counts as it is a mirror in every sense of the term, and I assume this site is what prompted this notice.

However, if a link is explicitly labeled as being an unofficial mirror, is it allowed?

If I say "You can also download ISO files from my unsanctioned, unofficial mirror, which is not affiliated with, endorsed by, or in any way connected with the LinuxCNC foundation and/or its members at <link>", is that allowed?

Not near a machine so i can not confirm this, but IIRC:
Yes it does Disable the machine.
No, it does not trigger e-stop.

Near as I can tell, this is correct. It disables the the machine, requiring it to be re-enabled, but it does not turn the machine state to "OFF". This is why you see the GUI turn "OFF", and halui.machine.is-on turns False. But that's not the same as toggling halui.machine.off. I don't think this is a bug, I think this is a misunderstanding of what happens when a amp-fault is triggered. If you want this to work, I think the best course of action would be to connect the pin to machine.off as suggested previously.

I think the images you're referring to are on linuxcnc.org/iso

linuxcnc.org/iso/image_2025-11-10-raspio...7-6-trixie-arm64.zip

Not sure what the big deal is, but anyway.

The only problem with unofficial mirrors being blocked is that linuxcnc.org/iso sometimes slows to a crawl unpredictably, necessitating an alternate route during random slowdowns (likely caused by spikes in website traffic).

Does this mean I should remove the link to the RPi5/4 images I've been working on. Which I have no issue with if this is the way it should be.

Thank you for your cooperation.

7C81 configuration for 7I78 on P1, INM on first 12 P2 pins

The inm module supports up to 4 MPG encoders,
it also has built in input filtering/debouncing.

The last 5 P2 pins are left as GPIO so can be inputs/outputs
as needed


 

 

What exactly do you mean by: Adding second spindle control to pyvcp?

It seems very strange to me because it works perfectly fine for me on several machines where I've installed potentiometers to control those two speeds. I honestly don't know the resolution of the ADCs on the card you're using. In my case, the control is very linear between 0%, 100%, and 200%, which is the range in which I have those two overrider speeds programmed. Could you please repost your configuration so I can try to help you?
