In hal show, the limit switch pins should show false (red) when not activated and
true (yellow) when activated, is this the case?

++Disclosure, my X1C was given to me from Bambu due to my YT channel, and I like it so much I asked to join their affiliate program.
Bambu has not contacted me on this issue, this is solely my opinion++

Having owned a home built 3D printer for 10 years, which needed constant troubleshooting and tuning, and never came close to the quality of the X1C, which just works, I dont really get the upset. Maybe I understood it wrong, but didn't pick up Bambu proposing a subscription model, or any of the other scary scenarios floating around. Maybe they are creating potential back doors for them, but the upset for what might happen (but hasn't, and probably wont due commercial suicide) seems excessive. No one expects a consumer electronics product to last for ever these days. If Bambu goes crazy and really screw around their customer base with a sub model, locking out existing features, etc, those users would just switch to whatever the latest/greatest printer from the competition is. Adobe and autodesk used dominant market positions to force subscription models. I use Gimp and Freecad. Printers are too commodity for Bambu to successfully wield such market power as Adobe. They would just loose their market if they tried.

As a user rather than 3D printer tinkerer, closing the software eco system seems pretty irrelevant to me. I was never going to switch from the Bambu slicer to another one, as their integrated one works fine. I'd used Slicer and Cura on the old printer in the past, and didn't really care which slicer I used, if the result was okay. If I compare X1C to the Canon, HP etc document scanner/printers in the office at work, those also have completely closed software eco systems (and share diagnostics with the mothership*) as have all printers for decades, and no one seems to care much. No one (well no rational user, I used to run 3rd party software driver for an early epson photo 870   would even consider loading there own print drivers for the document printer.

Bambu has stated they will not close the use of 3rd party filament. If they reversed on that, I would understand people getting upset, but the core software being closed off? If people have a religious need to open source, and tinkering, they were never going to buy a Bambu, they will build a Veron. Most users dont give a rip about the firmware and software, as long as it works.

I know the 3D printing community has a strong open source culture, and a lot of the tech dev was done by the community. That is the only point where I sort of understand the upset, that years of tech dev from the hobbiest have been hovered up and commercialised. However it doesn't seem to me that Bambu need be singled out for special attention there either. They didn't cause that, as there are hundreds of 3D printer manufacturers who did exactly that. At least Bambu did it well.

Isn't this also what Tormach did with LinuxCNC --> Pathpilot? I never saw equivelent upset about that here.

*with corporate document printers, I am sure you can deactivate such data transfer, and my understanding is you can deactivate it on the Bambu printers as well.

There are no search options in Kunena.

In this example no scurve is active. The traject position is incremented 0.01mm each cycle.

The spikes are caused by bspline interpolation.
Even when the bspline has a high resolution like 1000 points. It wont change.
So maybe change it to a linestrip. and then interpolate the linestrip. See what happens.

 

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.

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

The below packages are installed in the image.
