Warning: Spoiler!

Alright its starting to look like the inmates are running the asylum. Everyone just hold on for a moment, breath in and out, and cool our heads. I know english or linuxcnc isnt everyones first language, but it looks like everyone is working off each others confusion, and you guys are spiraling out. I think there are some core concepts we arent all understanding completely. Its clear that you guys are smart people, so lets hold on for a moment and regroup, and always read the manual. If you atre getting frustrated, just start from page one and read. If there are things getting lost in translation on the documents, letting us know would be great, and we can change some of the wording. I know the docs arent perfect, but the core concepts are the same for the whole of remora.


Also, if its a remora specific question, it is best to ask in the thread. remora isnt really a big wide linuxcnc thing, it makes it harder to find your thread.

  

 
First of all thank you so much for your interest in the problems of all of us newbies. And yes I can't speak English at all, I only understand a few technical words as the little I know was learned by myself. I'm sure that the things you wrote in the following posts will solve all my problems even future ones and I will keep these posts as documentation.

I have one last question, is there a specific post of remora? Could you kindly link because I thought it was this post here! Thanks again infinitely!!!

a little help links for NVEM RT1052 pins1      NVEM RT1052 pins2 

Hallo Hans, bei deinem ersten Post - meitest du Hartberg in Österreich - Stmk?   Falls ja, bin aus Rohrbach a.d.L.
Eventuell könnten wir uns gegenseitig etwas helfen.

Where can I find an example of how to connect and integrate a handwheel (MPG)? Is it possible with Remora to use both a handwheel and an encoder for the spindle, or is only one of the two possible?

The background is that I drive the spindle with an AC servo, and this should be controlled via step/dir as a C axis. In the Gcode, the spindle should then work as a C axis, depending on the call, or rotate as a spindle. For the C axis to function correctly, not only the index must be evaluated, but also the angle via A/B.

EStop tested on NVEM board, works with mushroom button. In the GUI, EStop can be released and the machine started if the switch is not pressed. If it is pressed afterwards, the machine goes back into EStop.
Thanks to the "stupid" AI, I now seem to have managed to get a command to be issued on Joint2 with G0 C10 or with an M3 S300.

Wow, something I actually know something about on this forum.

For anyone wanting to explore FreeCAD I would highly recommend using the latest development versions. There are nightly builds available through a ppa but I personally would (and do) opt for the near weekly builds of the AppImages from here - github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds - Linux, Mac and Window$. No worries about dependences and if any given build has a showstopper bug, you can still have the last weeks to keep going until the next build that will, 99% of the time have that bug fixed. Lots of advanced and more complete features keep showing up. Especially in the CAM workbench. 

FreeCAD is my daily driver and unlike this LinuxCNC stuff, I took to FreeCAD like a duck to water. I personally find it very easy to use but I know I am amoung only a few that do. There are a vast number of vids on youtube and a forum every bit as active as this one to help get you started.

For the money, you won't beat it, and before you know, you will be knocking out parts left and right.

I am a beginner in linuxcnc ethercat I am waiting for your help
.4 Chinese drivers work without any problems in the same system operating modeLs servo ????? op problemsethercat slaves    ?????????
 I couldn't find the reason why it was switching to op mode and not switching to it.I am adding demesg and other outputs that you can askI couldn't find the reason for this, I would be very happy if you could help me. I bought 10 of these servo motors, but I couldn't solve the problem of whether it was connected or not.
