I installed it on another computer a few weeks ago and there was no problem.
I think Linuxcnc's ethercat support can be turned off by someone who provides this support whenever they want.
I think Linuxcnc is not suitable for professional use because an installation that could be done last week cannot be done this week.
For example, let's imagine a person who is building a machine with Linux, everything is finished and it is at the operating stage. There is an ethercat problem right now and it can't be solved. How can it wait for it to be fixed? It can't wait, that's why it doesn't use Linuxcnc, it uses professional devices. Yes, Linuxcnc may be free, but it doesn't matter if it is free if it doesn't work when it should.

Well look at what happened to all those pros using Windows a couple of weeks ago.

I'm sorry but this kind of consumer attitude is not helpful, if you need 100% reliability and availability then you may want to consider investing the 20 or 30 grand in a professional solution.
You may not be aware of this but pretty much everything here is the result of donated time. Made available to the public to enable people like you build things they could not otherwise dream of making, this forum included. Where is your contribution to warrant such a fit?

Linuxcnc is best cnc

Sorry, just saw this. Digital works, analog doesnt? Have you tested both the analog in and out, or just the out?

I'll double check the code vs the specs and see if anything leaps out.

IIRC, the Ethercat people just did a major version upgrade after literally years of leading up to it. We should probably either pin LCEC to v 1.5.x or see what it takes to fix whatever upgrade problems are happening. I'll take a look at it later today if possible.

The larger issues are kind of complex, and discussing them would get in the way of fixing the short-term bug. I'll just say that if you really want to depend on something in a production environment, then you either want to be paying someone for dependable support, have the ability to fix just about anything yourself, or be able to live without it for a while. This isn't LinuxCNC-specific, or really specific to any technology at all.

I don't know of anyone offering this level of support for LinuxCNC today, but I've never really looked.

Seems to be an error message that pops up when secure boot is enabled.

See:
forum.linuxcnc.org/9-installing-linuxcnc...i-o-privileges-error

Here is a post by dewey (confirming the issue of secure boot and parallel port):

According to this the issue was supposedly fixed a while ago.

rodw is very helpful to everyone regarding ethercat.

I'll standby. That's awesome news to hear, I know you'll figure it out with time. Oh man!!

ps. yes gigabit phy. Correct. If you need the bitstream, shoot an addy I can email -or- a drag & drop box. 

@meister 

A 1000 meg base ethernet/phy onto "rgmii_txc & rgmii_rxc" buffers. Have a look and let us know if RIO can deal these two buffers. 
Let's get this lag over with and league up a notch! 

Synthesized, Placed and Routed Code in hands. If interested, DM an address I can send bitstream source too [16mb]. 
RTL8211FD Schematic attached (pdf). Same real-estate as the wizzy part, 10x performance increase though.


 

Hi...new here..I have a home built cnc running mach 3.. 6 axis and need to quickly switch to linuxcnc to take advantage of the 9 axis that I will need for an upcoming project. done some reading to be confident it should not be a problem but i am not real clear on what i will need to order in terms of hardware...I currently go from typical BOB to Ethernet smooth stepper which seems like need to be replaced...currently steppers but may want closed loop also..Also pc requirements?

If anyone can list what would be required I would be so grateful as I do not have much time to research...

Thanks,
Rick

puhh, realy gigabit ? hmm, if it's work

i can run LAN8720 & RTL8201F on the tangprimer, so there is allready code for it as a base


at the moment, i try to debug a little bit the old w5500 driver and found out that it do not receive the last package

I guess it's more like a hallucinating 8 year old who read too many twitter and youtube comments and thinks he knows everything about the world. And of course, don't listen to the people who wrote these algorithms, because they do anything in their power to pump up the hype.

And sure, these bots can be valuable in some niche area's such as sorting through huge amounts of data which would be impossible for humans, but for many things they're not better than mostly random guesses at the moment.
 

I will actually have to respectfully disagree to this one. "High"schooler I think would be pretty relevant. I have never seen and 8 year old whip up a 1000 word arduino sketch in under 5 minutes. That is one thing that I do use GPT for. It is actually pretty decent at C code... I have lots of microcontroller running of its code. And its also better at finding things on the net than, I hate to say it, Google...... Im sorry oh great oracle, please dont smite me for saying it.....

  I am making Gmoccapy full screen, but I do not want the user to close the cnc screen without entering a password. should not be able to access anything other than the CNC screen without entering the password. How can I put a password on the exit button? It will be like a settings page and I should be able to set the password.
How do I check the g code renewal key from Classicladder?

There does not seem to be any parallel port reference in the hal files.

Maybe the generic "cannot gain I/O privileges" message includes
the parallel port warning.

Maybe the wrong hal file uploaded?
I am sure i saw this same issue before here, it did have mesa and parallel port stuff for a Mesa only config, usually ends up like this due to just clicking on stuff in the wizards.

Done, thank you.
