Replied by mwc on topic More advanced EtherCAT setup questions

Going back to setting drive parameters, is there anyway to set ModParam with the generic cia402 driver, by addressing the required register directly and not using a 'named' parameter?

 
I'm back working on this, and have got the drive digital inputs working, however I'm back at needing to set a drive parameter, so is the above possible, or will I have to write a driver?

cia402.comp - can't compile in 2.10-pre2 was created by tuxcnc
I am using a file from github.com/rodw-au/cia402_homecomp/blob/main/cia402.comp .
It has always compiled successfully for me in the past, and it has nothing to do with the internal homing routines of the drives.
I am attempting to transition from LinuxCNC 2.10-pre1 to 2.10-pre2.
I have managed to resolve a few issues, but I have no idea why `cia402.comp` refuses to compile.
The full output is:

The initial lines regarding the replacement of old variable types with new ones seem fine, but the parts referring to lines 139 and 140 of the `cia402.comp` file look suspicious to me.
It appears that the declarations on lines 139 and 140 are incorrect; this is likely the source of all those error messages stating that a floating-point constant cannot be assigned to variables whose types the compiler fails to recognize.
I could be wrong, but I don’t see any other likely culprits.
Additionally, there might be a type conflict further down in the code, as `hal_real` in C corresponds to `double` rather than `float`.
In any case, this problem is beyond my capabilities, and without `CIA402.so`, my machine simply won't work...

Replied by awallin on topic Tuning Steperonline A6 Servos

script for tuning the servos over the ethercat bus with the most important parameters:
github.com/shulter/biber-ethercat/blob/main/tools/servo-tune.py
 


 
Thanks for posting this! Seems to work without much modifications (I have just XYZ, no gantry config).
Is there a way of saving the tuned parameters also over ethernet? IIRC the tuned values with this script are not saved permanently to the drive?

Replied by awallin on topic Technical questions about CIA402 and homecomp.comp on A6
Can someone give an update on the current (October 2026) status of homing with the Stepperonline A6 drives?

I got my servos moving and roughly tuned, but haven't been able to get homing working.
I tried to follow some of the cia402_homecomp examples, but I just get a following error immediately when starting homing. What are the exact pin-connections needed with cia402_homecomp?
FWIW I plan to use the negative limit switch + forward movement to next index method - not that the exact method for homing should matter much for getting this working..

7I92T config for 8 encoders, 5 PWMgens, and one stepgen

Wasn't sure if you needed DIR on the PWMs so two of the PWMgens are
PWM only (no dir) due to  pin limitations, can easily change if needed.

Replied by dberegovoy on topic Lathe Spindle Encoder: What are the options for EtherCAT?
Hi everyone, 

I just received my Omron NX-ECC201 today. The first thing I did was verify that it works, and I couldn't resist playing around with it a bit—I successfully toggled the LEDs on the output module directly from a Linux terminal via EtherCAT. 

Now I am planning the next steps for my machine setup. I need to process an encoder signal, and after doing some research, it seems that the NX-EC0222 or NX-EC0122 modules would be the best fit since they support differential signals. 

However, my current machine encoder operates on a 5V TTL signal. This leaves me with two main options: 

1. Convert the 5V TTL signal up to 24V single-ended.
2. Convert the 5V TTL signal into a differential signal to feed it directly into the NX-EC0222.

I am leaning towards the second option (differential) because I feel it is much more noise-immune and future-proof for upcoming retrofit projects. 

I would really appreciate your advice on choosing the best Omron module for this setup to help me narrow down my search. 

Thanks in advance!

Thanks , so I will not use emoticons jejeje.

So, follow up: 
I will install as soon as possible the last version from...  instructions buildbot.linuxcnc.org/

so maybe errors are already corrected...

In the meantime, I'm attaching the gcode as modified by the "convers" in my QtPlasmaC. I saw I don't have the original produced by SheetcamTNG, I saved this on that one, so I only have this one (that is the one I was using).

About the error n 2, the "cutting in the air", while finishing the job (it's for a cantilever in my "borning shop"), I discovered the error is
when I press my custom button "Goto last X0Y0" before the Z axis finishes to reach the "idle height" after finishing a cut.
The button is a G0 X0 Y0 only (or it has Z0 as well? I have to check).
If I wait the Z axis to be at the idle height before pressing that button, the next cut properly works.

Bye, thanks,
have a nice day!


It did not attach the gcode, so I put it here:

Interesting to see someone working in a similar direction! I’ve recently done something similar with my linuxcncMulti project. My version is already running and available to test online.

It remains compatible with existing LinuxCNC configurations and supports a large part of Siemens NC syntax, including transformations and measuring cycles. It also includes material removal simulation.

A more polished visualization using Godot is currently in development.

You can try it here: www.cnc.gmbh

Would be interesting to exchange ideas and compare approaches!

Hi :)

thanks Tommylight for moving the thread to the correct forum section, I thought I posted it to the PlasmaC section but I mistook posting it to the general section image missing /media/kunena/emoticons/unsure.png

Thanks Snowgoer540, I will post/attach the gcode as soon as I get to the machine: I have the original gcode produced by SheetcamTNG and the modified gcode I saved by the QtPlasmaC I was actually using.

I think about one month ago' I installed the LinuxCNC last version downloaded from linuxcnc.org (Current release: 2.9.10) because the one I got was skipping some hole parts (I found a post about it)... I thought it included the last version of QtPlasmaC.

So if I understand the one included is not the last version, so I would like to install the correct one.
How can I install the last QtPlasmaC version? And, I did not understand, are there two locations where QtPlasmaC is?
Where is the most recent one and how to install it please?

Thanks to all in advance! :)

Alberto.

Thank you! :)

I have floating around in my head. I have been learning Python coding but it has been a frustrating

And as luck would have it I am thinking of using Claude Code.

1) without your gcode it’s hard to tell what’s going on.

For the others, I would say that development for the qtplasmac in 2.9 stopped in August of 2024. Any and all bugs that have been brought up since have been addressed in 2.10.

It’s one of the unfortunate parts of the project that releases take years between versions. So much has changed in QtPlasmaC between version 2.9 and 2.10 that maintaining bug fixes in both locations for QtPlasmaC was not something I wished to spend my time doing.

Before he retired from the project, Phill rewrote a lot of the conversational code so I would imagine your issue has been solved in 2.10.

Thank you so much, that's excellent news.
The pinout doesn't matter since I will be soldering the cable myself.
I'm planning to use an EtherCAT setup with discrete I/O modules, so I mostly need the encoder functions on the Mesa card.
Could you please make the firmware with 8 encoders, 1 stepgen, and the remaining pins as PWM? I would need it for both the 7I92 and 7I92T, but the 7I92T is the priority since I have two of them. Any pinout layout works fine for me.
Thank you in advance!
