Yes. It is a parallel BOB.
In stepper configuration wizard, i set Y as normal axis, and the secondary motor as Y tandem. (read that somewhere here in the forums)
Both sides have their own limit switches.

Testing in the configuration wizard:
Setting Y axis as normal, and the additional motor as Y tandem.
Then going forward to "test" only 1 motor moves.
If i swap which is Y normal, and which is Y tandem, the other motor moves, and the original motor does not.

Deciding to go ahead and finish the configuration wizard, and test it in linuxcnc, the same issue occurs. It attempts to home only one motor
This is the issue i've been trying to find a solution to.

Hmm. That's unfortunate.

They talk about getting the machine in the proper state to rerun the tool, I assume with all the proper G codes in operation (G17 etc.)

Most of the machines I ran back when I was a machinist by trade remembered those unless a M30 was called. Unless you started from a different tool, the same state was still in effect and the machine just started from the line called.

If you called a different tool, you might need to do some wizardry to get the machine back in the proper state.

Anyway. Looks like I am not the only one with this issue.

Thanks for the help.

Since you failed to mention, i am assuming this is a parallel port setup, so is it?
I think the 2.10 version of LinuxCNC will have tandem axis in wizard for parallel port, for Mesa there is already any combination possible in the wizard.
There is no howto as it is very simple, open wizard, choose axis and what axis is tandem, some math with motor/pulley/final drive/, and save, test.
Also, it seems you came form Mach3 side of things as there is no slave in LinuxCNC, there is tandem joints and can be more than two fro the same axis.
And using LLM for this is still just plain useless, and so is google, next time try duckduckgo.com it still seems to find stuff that is fully hidden to google.
Finally, a qustion before you wander again to the deep end of the pool:
Do both sides of Y have their own home switches?
That is a must to be able to square the gantry any time the machine is homed.
But, if you do not need gantry squaring, you can:
-wire both motors to the same drive, in series as the cable length is not an issue, or in parallel but both cable sets must be the same length
-wire both drive inputs to the same PC output, be it parallel or Mesa or Pico or Remora or Rio
-set in software/HAL to output of Y axis to both drives, simply by choosing Axis Y twice in the wizard.
All of these do not require any home switch, and can not do gantry squaring. But they do work with switches.

Recommendations for a dual NIC SBC or mini-pc

Category: EtherCAT

aaeon (asus) has a dual nic pico itx motherboard with a celeron n150 that I have been looking at for linuxcnc/ethercat. It is I think $248 (plus ram and m.2 ssd). it also takes 12v power via terminal blocks so it seems like a good option at least on paper.

While i'm no stranger to linux, i have to admit, trying to get my machine up and running in LinuxCNC is the equivalent of throwing a toddler into the deep end of the pool, and expecting them to win a 500m butterfly race. I need help with this. because my experience with LinuxCNC thus far, just makes me want to wipe the hard drive, and find literally anything else. 

There's just NO documentation on how to do it. There are small hints here and there, and a plethora of forum posts that tackle small bits of this or that, but not a single unified, digestible "this is what you have to do" type of guide. I've spent the better part of a week, crawling google, bing, facebook ,the forums, the documentation, the github, and it's just EVERYWHERE. Most of it, is seriously old, and outdated information. 

At the end of the day, i just feel swamped with a mountain of unusable information, configuration files, and a plethora of "almost there" configuration wizards, and i've made absolutely zero progress. 

Yes, this may seem like a rant, and honestly, it kind of is. Something as simple as slaving one motor to another shouldn't be this convoluted. A simple drop down and checkbox in the wizard should have been all that was needed to slave A to Y. 

// END RANT //

All i need, is a step by step proceedure for slaving my A drive to my Y drive.

Thanks for the github link. I will look into it in detail.

Currently everything is doing what it´s supposed to do, signal wise.
When i disable the estop relais (hardware wise) i can see a reset pulse as described in the hal excerpt above, using halscope.
halui.estop.is-activated just stays in estop.
If i set F1 in gmoccapy, the GUI puts out a warning about external estops being set. I have literally no idea what net could be the reason for that behaviour.

toggle2nist hangs when pressing an other button at the same time

Category: HAL

The Problem is the same as before.

@Aciera
So I did halcompile --install toggle2nist.comp.
I see a new pin toggle2nist_1.debounce so the update should be OK.
I also put the pause/resume signal direct to the toggle2nist without the toggle in front.

@andypugh
I dont understand "output pin from hal_input" my input pins from the gamepad are input.0.btn-base6 ...

Update LinuxCNC 2.9.5 on debian 13

Category: Installing LinuxCNC

You can try downloading the .deb file directly and manually installing.
(sudo apt-get install ./deb-filename )
The ./ is a clue to apt-get to look at a local file rather than on the repository.

It looks like Trixie has a more restrictive archive key policy than Bookworm, and it's going to take me some time to work that out as it's a subject I know next-to-nothing about.

Carousel with counts move x amount of pockets

Category: Advanced Configuration

"align-pin" isn't a physical pin (or, rather, it _can_ be a physical pin, but which one it maps to is dependent on mode)

In the step counts case:

github.com/LinuxCNC/linuxcnc/blob/master...s/carousel.comp#L292

And I am somewhat concerned that I have made an error there, as I don't think that the % operator will return a negative value.
I can see what my code was trying to do, but I suspect it doesn't do it.

Do you know what your counts (and scale) were at the point that the system got stuck?

(Solved) Initialization code for a rintelligent ECT60 fails when run on an ECR60

Category: Driver Boards

I checked the link you provided and find the note on page 16 interesting: "... This index 0x2001 only works on ECR60. If you change it on ECT60, please find index 0x2020..."
The developer of my code intended it to be loaded into an ECT60 (closed loop) driver and configured it for an open loop stepper. Given the above statement (if true), it's odd that he sets up register 2001 but not register 2020.
<sdoConfig idx="2001" subIdx="0"> <!-- segmentation/resolution for open loop -->
            <sdoDataRaw data="40 9C" /> <!-- 40000 counts/rev -->

"For fun", I tried adding this back into ethercat-config.xml, but the error condition remains.

I looked into downloading the package onto my Windows PC but it's unclear which download to use. They have quite a few and the link just goes to their front page, not to a specific download screen. To be honest, I don't hold out much hope that dropping it in place of my config file will make it work, but as you alluded to, perhaps it contains something the manual left out. Anyway, their comment above makes me wonder all the more whether there is key documentation missing from the User Manual regarding differences between the ECR and ECT drivers... sigh.

Another possibility is that pressing two buttons means that the button-release event is not seen. So check the output pin from hal_input too.

The logic for setting that HAL pin is here, it just reports the system state:
github.com/LinuxCNC/linuxcnc/blob/master..._intf/halui.cc#L2167

Is halui.estop.activate being driven at all? Is it false?
