Pncconf does not have pin numbers, for things like 7I96S PWM outputs
and SSR outputs (the things that are needed for spindle interfaces)
They are listed by channel number (the channel number matches
the 7I96S manual names and mesaflash listings)

Do you have a more complete spindle interface description?

It looks like the 7I96S analog output will need an external 12V or 10V source
(since unlike a normal VFD it looks like the drive does not supply a 10V source)

  the header pins on the mesa boardIt's a project that was stared a couple years ago that I'm trying to finish and now on my own its PM728v-t everything is working except the spindle that I'm trying to figure out how and where to hook up. pncofig has PIN numbers I'm trying to figure out where the number is physically on the board. attached image is what I'm trying to hook up

Hello everybody!
I am new to this forum, so first I want to thank everybody for all the information posted here.
I want to replace my old 32-bit computer running a 3-axis stepper cnc via a parallel port. 
What I succeeded in:

1. I bought a Raspberry Pi 4 and a Mesa 7i90 card.
2. I used my old computer with parallel port, connected to the 7i90 and programmed the 7i90_spi_svst4_8.bit firmware using mesaflash.
3. I downloaded the LinuxCNC disk image for the RPi 4 and installed it.
4. I connected the 7i90 to the Raspberry Pi (about 3 inch flat-cable, all ground lines connected). I can read the device configuration using mesaflash without problems (well after a new install of mesaflash from the git repository).

Now I want to start ``linuxcnc linuxcnc/configs/by_interface/mesa/hm2-stepper/7i90-rpi-spi.ini``. The GUI pops up and everything seems fine.
But when I press F1 to reset the estop latch nothing happens. Up to now I did not connect any drivers or switches to the 7i90.
I changed 'DEBUG = 0x7fffffff' in the ini-file and added a 'show' to the end of the ini-file. I attach the output when running the linuxcnc. I marked what happend when I pressed F1 by '******' in the text.
If you need more information (ini-file, hal-file) let me know.
Many thanks for any support, H. Hermes

Experienced some jitter as well today while running grandixximo's fork. I doubt there is any synchronization being done while the dc-phased pin is false and all pll-*** pins are 0. Ran sudo dmesg to see what is happening in the background. Maybe someone can notice something clear in the log:

Rod, I literally just did exactly that. It booted and worked perfectly fine, with the caveat that the .sources list for Aptitude is empty, and you need to manually populate it.

Once manually populated, the system was able to be connected to the internet and it worked exactly as you'd expect with regard to installing new packages.

I wanted to bump this thread and inquire if anyone was using the STMBL v5 on their LinuxCNC projects? With native SS support, small size and support for straight rectified 220v I have always felt it was an amazing solution. It is pretty well documented but I'm wondering how challenging it is to tune the drive for the motors once all setup? The instructions seem fairly straightforward but it is hard to know until you try!

Also big thanks to Freak for reviving this project!

Good morning, I bought an xhc-hb04 because mine had fallen and the wheel didn't turn well, but it still works. When the new one arrived, I immediately noticed that it stays on even when the PC is off, which the old one didn't. It's detected because if I remove the LinuxCNC dongle, it gives me an error. The working one has a chrome power button, while the new one has a plastic button. I think it's defective. What do you think?

I am working on updating the control an older Linuxcnc machine.  I need to make some modifications of the old GladeVCP it uses.  Are there any steps or instructions for updating older GladeVCP files (from Linuxcnc 2.7) to current versions of GTK/Glade for Linuxcnc?

aliexpress 7i92 have anyone used this card, how can use,https://www.aliexpress.com/item/1005011667901833.html?spm=a2g0o.detail.pcDetailTopMoreOtherSeller.1.7ccfDf5dDf5dYi

cheapen hahaha, aliecpres card cost 40-50 $ and mesa genuine cost ower 100 $ lot different price, hobby users not have money waste ower 100 $ only small card, need be lot lot cheapen can buy hobby cnc card.
and second, why waste lot money buy etc 160$ card if all same can buy aliexpress 40$ lot different price and stupid if waste lot money if not really need.

Hi grandixximo,
Congratulations on a viable solution to this long standing gap in Linuxcnc implementation.
I was going through how you have taken into account the kinematics in userspace for planning which is needed for kinematics bounds checking.
I also see that you have made the relevant changes in the kinematics defined in src/emc/kinematics/* files.
There is another set of switchable kinematics defined in the src/hal/components/*.comp files (method made viable by David Muller / aciera on this forum). For example xyzab_tdr_kins.comp, xyzacb_trsrn.comp etc.,
I somehow find the idea of implementing the kinematics as a loadable .comp module compiled by halcompile very fascinating and useful
Is there a guideline on how to transition those kinematics also to this new setup?

Is there stock available for purchase of the height sensor?

A couple of days ago, I saw 1 in stock, but when attempting to purchase, it said out of stock.

Epoxied electronics sure are hard to extract. I have had some success using a small butane torch or a heat gun to soften the epoxy with heat. Some kinds of epoxy turn rubbery an can be carved out in small bits with a knife while it is hot. But that is messy. It is too easy to burn it up or start a fire. Plus I end up with blisters on my fingers from working with the hot stuff.

Take care and have fun!
