That's cool. I had tried both Gemini and Copilot, and I didn't get anything close to as useful as that. Thank you again.

I'd like to eliminate my dependence on the "mill PC", which is still running Wheezy and some ancient LinuxCNC release.  So I'm considering a 7i96, so I can do things across the network.  But to be sure I'm not blind-sided by some bad assumption, a couple of questions:

I have custom code in the servo-thread currently.  (My X/Y axes aren't square, and the code corrects for that.)  Will this continue working, i.e., does that part of motion control remain in linuxcnc, and not in the 7i96?

Will I still need a real-time kernel?  Can I run linuxcnc from...  anything?  My laptop?

Will things like surface probing, and probed touch-off, still work, assuming the right configuration of a couple of the 7i96 inputs?

Anything else I should know about this transition?

e.g. touch tft or "waiting" for a analog value.

I have seen cases where the clothoid fit result looks like overfitting.

What exactly do you mean by 'overfitting'?

Just so we are on the same page here is my version:
 

Constantly forcing index-enable low would explain the issue with G33.1 in the post above:
forum.linuxcnc.org/10-advanced-configura...sues?start=20#282461

Have you tried using spindle synchronized motion (eg g33 or g33.1)?

So I modified the orient.comp such that it has an index enable cmd pin (i/o).

This allows it to start the orientation with indexing, once done, it will disable the automatic indexing.

It can still be activate again by setting the index enable cmd pin high again (eg. via custom M code).

Only software signals can enable the automatic indexing before spindle orient.

In hal i then use:setting this high manually (or via logic: for example put this high after an M3 command has been issued), it will make the system home once and do a spindle orient.

Hi everyone,

Since I haven't made much progress with the inverters and electrical hardware (i try to get the SIEMENS S120 running but its hard with linuxCNC ;( ),

I've been working on a concept for the hand-control-panel in the meantime. I dont like the original one that much, so I'm trying to build a new one and keep it as compact as possible.

I like the idea of it being mounted to the bed carriage, similar to a conventional maschines. I plan to design the lever for forward/reverse operation in a way similar to what was done with VDF. In the neutral position, it will lock in place, and to activate it, you’ll need to push it slightly towards the negative Z direction first. Then, you can move it up for left rotation or down for right rotation. All three positions will have a locking mechanism in the center, as mentioned. This is for safety and prevents unintentional movement when you have your head near the spindle and might get caught on something like your clothing.

For the keys I'm thinking about adding a Stream Deck instead of real switches. So i can programm different functions to the setup in the future. Could be very handy.
   

Best regards,
Tom

Hmmmm....
That's a sticky situation!

Here's a suggestion:
Go on Kijiji or Kleinanzeigen or Ebay or a thrift store or something and buy an oldish reasonably good PC for very cheap.
It'll work fine with the 5.4 kernel.

Maybe you have an older PC in your basement or your garage or something, try it out, see if it works.

Ask your friends and family if they have an oldish PC thay don't use.

Maybe it'll work!

Please post output of lspci and lspci -v

Perhaps lspci -vv too

A newer OS might not work well on older hardware,

For example, old graphics drivers for old GPUs are often broken on newer kernels.

Hi all,

Today i did a test using the clothoid algo.

It turns out, when doing a fast clothoid fit, (using deviation as trim dist) this takes around 0.5ms.
Everything is going well.

When using the excact clothoid fit method, it takes time up to ~200ms when it has difficulties to find a fit.
I will find a solution for this later on.

Most off time the clohtoid fits are ok. I have seen cases where the clothoid fit result looks like overfitting.
This could be investegated later on.

Here some 3d clothoid fit examples. Using look ahead = using endvel.
So far i am happy with the results.

 
 
 

Github is updated.

Newer versions are not always better.

Newer Java versions are generally always superior and usually come with no real drawback.

However, not everything is like that.

I hate everything about Windows 11, I think it's ugly, unintuitive, annoying, and the GUI is a bad rip-off of GNOME and macOS.

Oftentimes, new versions bring good things and bad things.
The improvements, reduced familiarity, and regressions often almost cancel out.

For example, Ubuntu 24.04 LTS is not immensely better than Ubuntu 22.04 LTS; upgrading is not worth it.

Was kann ich von der alten Konfiguration weiter verwenden, was muss ich anpassen und was muss neu erstellt werden?

Um zurück zur Frage zu kommen würde ich wie schon erwähnt mal probeweise die neue Version auf eine zweite festplatte installieren und deine jetzige Konfiguration mal laden dann kann man auch gleich auf konkrete Fehlermeldungen eingehen.

@scda

The only thing I changed is: uncomment "is_oriented = 0" (otherwise I was not able to run multiple M19 commands in a row).

After digging out my config from back then I notice that I made the same change.

Yes that's the issue with the M19 command. But could probably be changed in a new release ??

thanks for confirming that as I thought I was missing something and yes that could indeed be changed.

What makes me wonder is why  constantly forcing index-enable low does not cause a problem for you.
