I have a question. Is it possible for the machine not to start when I press the Play button, but instead to load the G-code?

I can agree there is a piece missing. Rod has done a good job of describing the installation of the ethercat components in the stickies.
There is info on the linuxcnc-ethercat component and drive interfaces here github.com/linuxcnc-ethercat/linuxcnc-ethercat with some examples. Unfortunately some links seem to be broken and the examples are few.

An overview is needed that describes the roles of the lcec component and ethercat-conf.xml and the integration into hal with pin assignments.
Also, since there is no dedicated tool like pncconf or stepconf, how to set up an Ethercat linuxcnc machine, at least on a general level.


Sorry, my German is bad. I can read it but no-one understands me when I write.

Plug it into the male header on the board.
Where it aligns with Pin 1 on the board, that will be Pin 1.

Cant do this anymore bye all wrote:

It's a one to one connection. Pin 1 to Pin 1 etc. The wire with the red tracer is pin 1.

I have a 26 Way IDC Line Socket from jaycar here in Sydney image is below but it has no pin numbers marked.  Searched like mad but no luck.  Your help will be much appreciated. The D25 IDC has numberings marked!

Ok that's been known not to work, the 16GB is a new board and you have been only the second user to bring up an issue.

I've just upload a new image, not tested on 16GB model but 4GB. It may work on the 16GB model.
forum.linuxcnc.org/9-installing-linuxcnc...5-test-images#319747

All images have been tested on a 4gb Rpi5 bought int Nov-Dec 2023, updated with latest EEPROM. Not official images by any length. It is recommended to use Balena Etcher. Rpi Imager has had issues with the images built by the program suite used to build the images.

The image below is not recommended for use and is only being left for historical reasons.

This one has Mate Desktop, latest Linuxcnc Packages built from 2.9 source, ie: has hm2_spix driver. SPI enabled by default, no messing with config file. 6.12.10 rt kernel
drive.google.com/file/d/1EnvDj8BY6zotSFk...E70/view?usp=sharing

The below packages are installed in the image.

Linuxcnc packages available here if anyone is interested.
github.com/ozzyrob/rpi-linuxcnc-packages...62642dde63_arm64.deb
github.com/ozzyrob/rpi-linuxcnc-packages...62642dde63_arm64.deb

Mesaflash 3.5.10
github.com/ozzyrob/rpi-linuxcnc-packages...ash_3.5.10_arm64.deb

Just bought it. 16gb

It's a one to one connection. Pin 1 to Pin 1 etc. The wire with the red tracer is pin 1.

Ok 120GB is going to relate to storage not ram.

What is the spec of your RPi5 ?
What image did you try ?
How old is your Rpi5, when did you buy it ?
Could you possibly take a picture of the screen ?

I cant get Linuxcnc to boot  on pi 5. 4 skulls and page full of text. what am i ding wrong? 120GB pi 5 

That worked thank you!

I am now getting a "joint 2 on limit switch" error when i try to jog the machine on start up. The only other thing that changes is i went from gmocappy to axis (since i no longer have a touch screen).

I went to hal show and tested all three (still waiting on the fourth) limit switches and both estops do what they should.

Should i undo the "-not" ? If that was the case shouldn't it be all the joints?

A cleaner, linear response signal could be the ticket, as I have fiddled with the PID parameters quite a bit as well as my Z axis velocities and accelerations and it is still not really where I'd like it to be.

Have you considered linearizing the output (with lincurve) before feeding the linearized distance to the
PID loop?
 

 

PCW: That is not something that I had thought to try. I'll have to give that some thought and see how it performs. Thanks for the tip


prokopcio, I'd recommend starting a new thread in this subforum so we can discuss your design. Looks promising!

The T4 should be fine with a Mesa 7i96s Ethernet card. There might be a couple of tweaks required depending on the network interface but we can deal with that later. I cover stuff here docs.google.com/document/d/1jeV_4VKzVmOI...diY/edit?usp=sharing
