Peter, 
we have found that they are still issuing patches at kernel.org. Instead of Rokyas patch, try this official 6.13 patch
www.kernel.org/pub/linux/kernel/projects/rt/6.13/
Let us know how it goes.

A big thanks to royka for making that patch.

Just built 6.13 for x86 (which needed that patch)

Seem like it's got quite good latency on my test machine
(noticeably better than the 6.11 kernel I was running earlier)
 

DRIVE = TB6600
The above should not be in the ini file, or it must be omitted by putting # in front of it.
We need more info on the drives/motors and general description of the machine.
Another thing wrong with the ini file is the PID values are all 1, they should all be 0 except P (start with 10 to 50) and FF1 (start with 1 and lower it as needed when tuning the drives).
You should really read this first and make sure the stuff checks OK before powering the machine as it might run the motors at full tilt if something in wiring or config is not OK

Hi all, 

Looking to help a friend do the same thing as this thread, but with a 7i97T for the servos and a 7i78 card for the stepper for Z and THCAD2 for Arc Voltage. 
I could use some help reviewing the hal and ini files to see if I'm on the right track.  I built a stepper machine before with a 7i96s and THCAD2, so have some experience with the setup using PNCCONF.  This is my first attempt at editing the ini and hal files directly.  I combined the basic 7i97 file, with the JT's configurator tool, and the plasma specific info from my 7i96s config.    My main question is how to correctly identify the board names in the files.  In the ini file it shows 7i97T as the board and 7i78 as the card, but I don't see how the 7i78 board gets translated to the hal file?  Ignore the scales, drive values, and pin assignments for most of the signals for now. 

Also, the servos are Cleveland Motion Controls p/n MTE3528-508BG, does anyone know how to determine the encoder scale on these?  May just have to measure it once the system is configured.  

Okay, I put created a new project in sheet cam and put the run post processing and went over into CommandCNC - Star Lab and when I hit Run From Line it says Program exceeds machine maximum on axis Y and axis X. please help!!

M3 screws follow the socks.

On a serious note I'm going to delve into the abyss that is BSPI, and see if I can do something to read a SPI ADC. Hopefully something that one can get readily from Aliexpress. Though that kind of shenanigans with require at least 4 pins.

Rpi Images are up now.

Once again thanks to Andy for making it all happen.

Wow Pete, are you Soloman ?

Yes (this appllies to most step motor drives with opto-coupler inputs)
2.
Yes.

Yes, you can make a little loop at the drive.
(if you are good with a wire-stripper you can do this with a single piece of wire)
 

Thank you for your times and your kindness PCW. Best regards.

What kernel and Ethernet hardware do you have?

uname -a

will give the kernel version

and lspci | grep -i eth

will usually find the Ethernet hardware

What is the Host PC?

Have you run a latency test?
 

Hello
Im new to this forum maybe someone can tell me theirs actually works after waiting weeks for my new 7i96s all it has given me is grief from ethernet driver errors to update errors. tried the newest release didnt work. tried older ones they are poopoo. Do the makers of this software test it doesnt seem like it. Is there any software that works with this board without being a genius at linux. I know im complaining a bit Ive spent days to no avail.Im bald from pulling my hair out.You would think Mesa would test it with linuxcnc.I know linuxcnc used to work now everything is horse menure.
     I was told it started with implementing ipv6. who cares change it back.no matter what i do i cant get any pulses.

OK, moving it back for now, let us know if and when we need to move it.
Thank you.

The only reason I put it there instead of here was for a broader audience. I figured maybe someone might know about sources for LeadShine products who might not read the EtherCAT forum. Here is fine, though! No big deal.

cheers,

LM331 Is cheap and easy to find, amazingly i can find it here, although i can not find M3 screws!
