Does nobody really use Probe Basic Lathe?

It doesn't matter whether it's mm/rev or inch/rev, the same effect should occur with both if it's normal that you can't use a potentiometer.

I'd like your help in organizing my project.

i managed to recover a KUKA Kr15 robot but without the control bay.
and i'd like to get my hands on it and learn all about it. “Denavit-Hartenberg (DH) parameters”, ‘genserkins’ ...

After calling KUKA, they told me that only their KRC1 with old electronics was compatible with the KR15-1.

So I'd like to go with linuxcnc.

my first question is about the harware:

after several searches, i could see that the motors were siemens servos with a kuka label. the encoders seem to be cos/sin.

As for motor control, I'm a bit confused, on the motor nameplate you can see 1.5A / Uistr 146V / 6000/9000tr. they are in 3-phase AC.

after a long search on drivers, i find many with 200V -400V. I see that all the drivers have an encoder input. Is it wiser to connect the encoders to the drivers or to the mesa card? Are there AC drivers without encoder feedback?

-can a mesa card read cos/sin encoders? or do you need a card between the encoder and the mesa card?

 

Congrats to that, the debugger is a big big help, for some problems.
As you found out, the variable updates when the program is paused, or stepping.

Where did you read that in the manual?

Do you mean the image is not the full tab width in Axis?

I installed Pathpirate in 2.9.2 and when updating to 2.10.whatever, PathPilot removed it. I will reinstall Pathpirate but it would be nice to not to have to every time PP updates.

It shouldn't be necessary to use Multimedia CHEESE for AXIS data logging, right?

I think I successfully entered debug mode, but when I rotate the shaft, no change is detected in encCtn. Or I am viewing incorrect information. 



Eventually, as I tested the method further, I found that it actually counted…it worked.
 

Get Debian with the Mate or GNOME desktops, it is miles better than XFCE.
And, yes, it still has issues, Debian issues, but much less than before. Talking about 12 here.

In my case, it would be more convenient, as I only have Linux on the Raspberrry Pi 5.
 

For the Windows convenience I'd still recommend a debian Virtual Machine for the Rio, toolchains, configs, and bitstream gen. They are easy and quick to put together. Only challenge I could think of is the bit file programmer, some VM aren't good friends with USB2.0/3.0 (e.g. Hyper-v).

It's been a decade since I've VM anything and so I wouldn't know which is best to use. Bet Virtualbox does it USB nowadays though.     

You may also install LinuxCNC using the official Debian ISO. It works great.

However, I personally hate Debian.

I believe that Debian is the least user friendly, most confusing, most non-intuitive OS ever made.

Wi-Fi adapters may increase latency.

Be careful!

In general, it is best to physically remove as much unnecessary hardware as possible, then Install Ubuntu.

Just so everybody is aware, linuxcnc-uspace does not install on Ubuntu 24.04 LTS due to dependency errors caused by irrelevant Python version issues. Python 3.13 can run Python 3.10 code just fine!
