Problem with download LinuxCNC 2.9.10 Debian 13 Trixie PREEMPT-RT ISO was created by bill.anderson
I downloaded LinuxCNC 2.9.10 Debian 13 Trixie PREEMPT-RT ISO and ran the live version on my Windows 11 laptop, I used Gparted to partition the disk. I then rebooted to do the installation. The partitioner in the installation program would not recognize the internal disk I had just partitioned. I also tried the text based installer it didn't recognize the disk and it's partitions either. It there a version that will install available?
thanks
bill a.

Yeah the menus need work, I was just glad after 4 attempts to get it up and running on a modern OS and Joomla and Kunena. It took a few tries to figure out the steps for each thing due to restrictions with PHP and versions of Joomla and Kunena. And WOW I just noticed the spell checker works now!

Been seeing this for the last two days, notice the guest number, lowest i have seen it was a smidge over 4000, and i am sure those are no humans, well not all of them, some are for sure.
Checked the attachments and everything seems fine, statistics seem fine except profile views that are very low, the main menu renders vertically for me, i can reply quote and edit posts, will add avatar and edit profile in a bit.
JT, thank you, you have been magnificent.

Replied by tommylight on topic Custom PC build for my brothers company and more

Got the Ryzen 7 7700 for 215 Euro, ASRock B650M-HDV/M.2 mainboard for 120, and ... drum roll please 96GB of DDR5 5200 RAM for 146 Euro!!!

 
Good times, never again, only that 96GB of RAM is now well over 2000 Euro!!!
Bad times, that PC was today in my shop, the owner moved it to another city and somehow moved the very small switch on the GPU that switches BIOS'es from silent to overclocked and got stuck between not booting at all or booting and rebooting at random short intervals. Easy fix...for the PC, not for me as i sold it a while back!

It took several tries to migrate from where we were to where we are now but AFAIK everything works except the user avatars.

It needs some tweaking but it's beer thirty here in Swamp East Missouri.

Thanks a lot for your immediate help! That has solved the problem and I can go ahead with the rest of the project.
By the way, I have changed a bit the PID parameters, which has improved the situation, but did not solved it.
FF1 = 1
FF=0.02
MAXOUTPUT=30000
(1000 rpm and high acceleration of 5500 works now)

16 usec is fine but 2067 usec isn't. I would use a different PC but try the -nobase switch Tommy and I shared first.

Great. Looks like you could break this up with a complex entry for each input
          <pdoEntry idx="6000" subIdx="01" bitLen="16" halPin="DI-bit" halType="bit"/>

eg
Code:
<pdoEntry idx="60FD" subIdx="0" bitLen="32" halType="complex"> <complexEntry bitLen="1" halPin="CW-limit" halType="bit"/> <complexEntry bitLen="1" halPin="CCW-limit" halType="bit"/> <complexEntry bitLen="1" halPin="in-home" halType="bit"/> <complexEntry bitLen="13"/> <complexEntry bitLen="1" halPin="in-1" halType="bit"/> <complexEntry bitLen="1" halPin="in-2" halType="bit"/> <complexEntry bitLen="1" halPin="in-3" halType="bit"/> <complexEntry bitLen="1" halPin="in-4" halType="bit"/> <complexEntry bitLen="1" halPin="in-5" halType="bit"/> <complexEntry bitLen="1" halPin="in-6" halType="bit"/> <complexEntry bitLen="10"/> </pdoEntry>

Replied by rodw on topic Ethercat drive configuration woes

So tried lcec.activate, but that results in an error that activate isn't a valid command.
 
Should be:
Code:
initf lcec.activate servo-thread
YOu need to have the latest ethercat driver installed together with ethercat from that repo not from iGh

Here you go
ethercat_conf.xml = my known good config for Lichuan 4 axis open loop drive. Yours should be the same, just one less axis
ethercat_gen.xml is the lcec_configgen generated file. nice and short. When you get your xml working, raise an issue at  github.com/linuxcnc-ethercat

Reference this earlier issue #474  github.com/linuxcnc-ethercat/linuxcnc-ethercat/issues/474

install just your Drive on the ethercat bus and share these files:
ethercat pdos > pdos.txt
ethercat sdos > sdos.txt
ethercat slaves -v > lichuan.txt

Hopefully grandixximo will add support for your drive too. I think it probbaly just needs a tweak to the driver to support < 4 axes

I was just getting an urge to buy a Flexi-Hal Expatria Technologies card but this might be a better choice over a STM32F446. BigTreeTech Scyllia V.1 - correct - is there a github for the software?

I would expect FabScan to run on a Pi 5 with 8GB RAM without any major performance issues.

FabScan is written primarily in Python and uses OpenCV for camera processing. LinuxCNC handles the actual motion control, so FabScan itself doesn't have any hard real-time requirements.

That said, I haven't tested it on ARM hardware yet. All my development and physical testing has been on a Dell OptiPlex running LinuxCNC with Mesa Ethernet hardware.

There may be some minor adjustments needed for Python dependencies and CPU affinity, since my current launch configuration is tuned specifically for that machine.

If you're interested in trying it, I'd be happy to help work through any compatibility issues. It would actually be very useful to have someone testing on different hardware.

I have documented most of my prior setup. I will look for the live ISO images on the dowload page - I have a ventoy drive - its an easy thing to do.
so 2.8.4 first then.
