It's pretty much the same. It's actually fairly straight forward once you get the hang of it but I guess that's true for everything and I must have made a couple dozen sim models by now.
ProbeBasic has machine simulation that can be setup using a yaml file (similar to what some CAM systems have) but it is quite limited compared to vismach.

 

Your kinematics setup seems to be wrong:

Should be 5 joints and probably XYYZZ

Just a reminder (it's way down the list of repos now) but we did previously use pi-gen to make LinuxCNC images.

Bitrot has probably set in, though.

I don't think that "curve geometery" was ever a built-in LinuxCNC component. Did you install it from a comp file? 
If you have the .comp file then it will also work with 2.9.x once installed, but if you don't have the source file then you may be a bit stuck. 

If you have 2000ns jitter then you may be using the RTAI kernel? It is possible to run LinuxCNC 2.9.x with RTAI, but it's been a while since I created an installer package. (they have to be built by hand, as the buildbot currently has no RTAI builders, and it needs modifications to the Makefile) 
Having said that, I have a PC that gives 3-digit latency with both RTAI and Preempt-RT. it appears to be entirely random.

These are different questions and topics. In those topics where the authors forgot to say the main thing, I inserted the necessary pieces to make it easier for new users to search.

That's very pretty.

Is it any easier to comprehend than Vismach? I find using Vismach rather confusing (and I wrote the docs!)

I did something a bit like this using resolvers (with the difference being that resolvers are single-turn absolute)

You probably need a realtime HAL component (or set of standard components) that zeros the absolute portion of your adder when the index is seen. This is because of the way that the joint position feedback is used in the home offset calcuations.

There is an example .comp here:

github.com/LinuxCNC/linuxcnc/blob/master...ivers/mesa_uart.comp

Or if the PktUART is a better fit (it probably is) have a look at:
github.com/LinuxCNC/linuxcnc/blob/master...sa_pktgyro_test.comp

This works for me:

 

Which user interface are you using? And which version of LinuxCNC?

#### generally means that the parameter doesn't exist, but that doesn't make any sense for #5181.

You are typing (debug, #5081) not (for example) (debug, #<5081>) ?

Here is now a modified cia402 component together with a complete example on how to use PV (Profile Velcotiy) for an EtherCAT spindle drive.

Hallo,

ich habe mit einem usb linuxcnc live den rechner gestartet.

dann linuxcnc damit neu installiert. mbr wurde auf der entsprechenden festplatte

neu installiert. nach fertigstellung, neu gestartet. mein Linuxcnc und die maschine laufen wieder.

It opens a blank site but should download a .zip file (or open a popup about downloading a zip file with all the source files).

This is what I get when I click on the link in your last post:
 

A Mesa webáruházban, ha a támogatásra kattintok, csak egy üres ablakot hoz fel.
(www.mesanet.com/software/parallel/7i92.zip) vagy bármilyen más.
Csak a letölthető PDF.
Or is it just me that the download from the MESA site doesn't work?
Ezért kérdezem, hogy hol érhető el még a teljes kód.
