Very briefly:

In the hal file (use the sample: basic7i97 or use MesaCT to generate the basic configurations)
The PID output pin connects to the PWM value pin. You would change this connection to 
add the abs component so you have:

PID output --> abs in --> abs out --> PWM value

That is, for example, in the basic7i97 hal file you have:

net x-output     => [HMOT](CARD0).pwmgen.00.value

This would need to change to:

net x-output     => abs.0.in
net abs-x-output    <= abs.0.out
net abs-x-output     => [HMOT](CARD0).pwmgen.00.value

 

 

i'm not even close to being done but got the viewer hooked into a custom .ui file. i think i am on the downhill side of things now but this seems to be the hard way to do it but since i have so much time in teaching myself this i will finish what i started. but basically, it's done in OpenGL.

I understand, thank you! The duplication was unintentional. My apologies

Hallo Franz,
hast du die Kombination ServoStar - EL6751 in der Zwischenzeit noch zum Laufen gebracht?

Schöne Grüße,

You posted the same question twice, and that is not good as it makes it impossible for us to follow what has been answered, and for users to find the correct info when they need to.
Duplicate post was deleted.
Thank you.

Thanks a lot for the answer.

Good message: it is doable and I can use the RS Pro amplifier. Unfortunately the Mattke not. In any case, I have to forget the Tach function of the motors.

Sorry for my further questions - I`m an absolute beginner and not an experienced programmer. This are my first steps in learning to run.

Below I have formulated my questions in red font. I need to understand, whether the I/Os on my MESA are sufficient by number and by functionality.
 
Thanks a lot and best regards

Sorry, I didn’t quite understand what you mean by "without double posting". Could you please explain?

hello,

what is the common routine of AX5YZZ homing please?

regards

No double posting.

Thanks for your reply.Oh man, I thought that with the move to Python 3, turning operations would finally work.  :/

LinuxCNC is an incredibly powerful tool, and on top of that, it's freely accessible to everyone.The situation with cloud-based CAD/CAM systems is both a blessing and a curse.
On one hand, I’m glad they exist and that we have relatively affordable access to them.
On the other hand, we are completely dependent on big corporations like Autodesk, Onshape and others,
and at the mercy of their decisions. That's not good if we have to rely 100% on them.
Plus, there are all the usual pros and cons of the cloud.With NativeCAM, the developers gave us a tool that’s quite close to industrial-level technology,
like Siemens ShopTurn/Mill or Heidenhain Klartext.
Only a few small features are missing.Is there some kind of working group or active community taking care of NativeCAM?
Am I in the right thread here?From what I could find, the original authors are no longer active.
(If you’re reading this: I hope you’re ok, and thank you for your amazing work!)I'm not a programmer, but I know open source lives from community involvement.
Everyone pitching in is what keeps it alive.
I'd love to contribute in some way.My first experiments with AI and LinuxCNC have already helped me a lot.
In the past few days, I've learned more, and could help myself faster with problems without annoying friendly people with my inability.
Five years ago, I would have been completely lost without help. Today its still the same but i can do 90% of the job und and just need help for the last 10% lol :DMaybe this (AI) could be a way to develop and revive the project,
even with noobs like me involved.

Hello,I have a Mesa 7i90HD connected via LPT and a Mesa 7i85S daughter card.I need a firmware for this combination with the following requirements: 3 step/dir generators (for 3 axes) 3 encoder channels (for linear encoders) 1 PWM output (for VFD spindle control) some GPIO for external control panel (buttons, signals)  I could not find a ready 7i90_7i85s.bit file on the Mesa website.Could someone please share a suitable bitfile or point me where to download it? Thank you in advance! Best regards,Aleksandr. 

If anyone knows the source file where the 'Queue is not empty after probing' is coming from I'd be glad to look myself.

Likely these:

github.com/LinuxCNC/linuxcnc/blob/master...s274ngc_pre.cc#L1470
github.com/LinuxCNC/linuxcnc/blob/master...s274ngc_pre.cc#L1545

By the way, I used chatgpt to generate that code. I had to prompt it with multiple corrections.

It did not have any safe Z move to start with
It did not go back to X0Y0 between Z passes, so would have ended up out of limits / moving further and further in X and Y

(The point being that it is worth having some understanding of Gcode)

AI can generate code but dont blindly trust the output. This applies for other languages for AI. It can be a good starting point but often has issues requiring additional prompts

Hi Tom,

No one is using NativeCAM with Python 3 on Lathe because it doesn't work as is. Sort of ironic because it has a much more practical application on lathe than mill in my opinion.

In relation to canned cycles, G71 is only recently supported by linuxcnc and wasn't avaliable when NativeCAM was written. The latest bug is supposedly fixed in 2.9.4 as without this fix, the can cycle is limited.

Due to priority and time, I haven't tested it yet.
Cheers
