Etherrcat Master does not start automatically

Category: EtherCAT

Try `sudo systemctl enable ethercat.service`. That should tell it to start automatically on boot. I'm not sure why that wasn't set up on install, but it sounds like it'll fix the problem.

Question to operatingspeed glassscales with Beckhoff/EtherCAT under Linux CNC

Category: General LinuxCNC Questions

If the glass scale data can be linked into the LinuxCNC HAL layer, then LinuxCNC can use it.
I would expect glass scale date to be a relatively slowly-changing correction to the basic axis position, so I doubt that you would have to worry too much about speed.

Are you using the supplied LinuxCNC RPi image? If so it sounds like we might need to fix something in the setup. A CNC machine shouldn't screen-blank.

There is a whole thread about screen blanking here: forums.raspberrypi.com/viewtopic.php?p=433728#p433728

(Basically there are several things that can blank the screen)

If it locks the system, requiring a password, then it won't be the always-tricksy "dpms"

Whilst this can probably be done, it does feel like a lot of work to address a solved problem?

Might it not be better (if you really want to invent your own system and write your own drivers) to use some of the "smart" stepper drivers that accept pulse-rate requests over SPI?

Or, if your priority is a working CNC system, rather than a fun project: store.mesanet.com/index.php?route=produc...rt=p.price&order=ASC

I think it is probably worth investigating _why_ jog-accel-fraction isn't working on the second machine.

One drawback of ilowpass is likely to be that it prevents the joint.N.jog-vel-mode setting from working properly (as the rest of the system dosn't see the jogwheel stop)

E-Stop latch question

Category: HAL

Why do you desire a hardwired e-stop reset?

I have always set up my machines to reset the e-stop using the on-screen button.
I would never consider using the on-screen button to _set_ the e-stop, but it seems to me that pressing the GUI button is in many ways more deliberate than pressing a hrdware button, so is at least as good from a safety perspective.

What sort of step rates are you getting through the GPIO? (And which driver are you using?)

VFDs generally support numerous control modes, so even if you can't directly control it by EtherCAT you may be able to use Modbus, or even analogue voltage from an EtherCAT module.

Category: General LinuxCNC Questions

Hello folks.
I am wondering about CMM machine softwares. Are they using LinuxCNC? If they are not using LinuxCNC, would it be appropriate solution for these kind of machines? Do you know any open source CMM machine, CMM software etc.?

Thank you for your time.

Good morning and thank you for your reply.

As you may have noticed, I am the name here. I have tried to download the image that my colleagues have posted, I have tried the Linux CNC standard and I am not able to move forward. My driver is a Lichuan LC10E. Is there any basic step-by-step guide to help me achieve my goal? Thank you very much in advance!

Hi Russell,
good idea, thank you very much,
I would prefer riocore
it is no longer worth doing new things with the old version
Cheers.

So where is the thread?

Etherrcat Master does not start automatically

Category: EtherCAT

Hi,

a bit more than a year ago I got linuxcnc + ethercat running on a Beckhoff CX2040, back then version 2.8.4 and everything built from source (details in my blog post )

For various reasons I sat the project aside. Last Friday I finally started to work at it agiain. I was astonished to see that its now possible to simply install everything via apt without the need to build it from source.

So I grabed a new CF card and installed the latest iso. a year a go I had to build the ccat driver from source as well but now its bunled with the ethercat master. I simply had to enable it in /etc/ethercat.conf

After a bit of trial and error eveything works as expected excpet for one last thing: If I start the CX2040 there is no /dev/EtherCAT

I can't find anything suspicious:
sudo systemctl status ethercat.service

If I however do a sudo systemctl restart ethercat.service the master starts and works as expected.

The output of sudo systemctl status ethercat.service stays exactly the same.

dmesg gives a bit more:
