Once you're used to it it's fairly easy. No programming skills are required.....well to modify pin functions, the actual VHDL stuff is different.

This is the info I used to start building bit files for some clone 7c81 I worked on.

Hi
Unfortunately, I have no programming skills. I don't understand how this Xilinix program works.
I'm copying the pins in xx.vhd, but I can't save it to a xx.bit file because it gives me a bunch of errors and I'm just wondering what's wrong.

I'm completely at a loss.
If I give you the inputs and outputs, could someone who knows something about this make this xx.bit file for me?

I'm going to write a separate 32 bit executable that loads the shared library, and presents a named pipe that I can access via Python.

Loading 32 bit shared library with GladeVCP/python on a Raspberry Pi

Category: General LinuxCNC Questions

I need to load a 32 bit shared library from GladeVCP/python to communicate with an existing machine. This shared library is only available as a 32 bit library for ARM systems, and I want to see if this will run on a Raspberry Pi. I don't have access to the source, so I can't recompile arm64.

Is there any way to do this, or do I have to run on a x86_64 machine?

This is some lines that related to ethercat from sudo dmesg, is the problem with sync manager from xml file? or is it because some pdo from my drive didn't match

Which LinuxCNC HW for 2026+?

Category: General LinuxCNC Questions

When you get a following error, is there a dripped packet?
that is, is hm2_cardname.0.packet-error-total 0?

What are your following error limits?

Can you post a hal/ini file set for a system that exhibits these issues?

I ask because getting following errors and not network timeout errors, that is:
"error finishing read"s is odd and suggests a setup error of some kind

If your PC has a Realtek Ethernet interface, have you installed the DKMS driver?

(the stock Realtek drivers are hopeless latency wise)

If you have in Intel MAC, have you turned off IRQ coalescing?

Have you pinned the Ethernet IRQ to the last processor?

Some systems require disabling EEE or PCIE power management als

Category: General LinuxCNC Questions

Thanks, all.

In general, I like the Ethernet solution, especially because it comes with a built-in galvanic isolation.
What I dislike is, that this more or less rules out all notebook solutions, bc I need a network connection.

From what I experienced, but maybe it was all just bad luck, is that all internal WIFI connections do not work,
except for a couple of devices with a PCMCIA wireless card. I did not try every possible combination, but also
USB to Ethernet adapters seem to have a severe impact on latency.

Is my 7i91 too old maybe?
Of course, I set up everything with the help of pncconf and used the default settings wherever possible.

I had latency (network) test running for days without issues; I programmed a Python script to let the A/B tables
rotate for hours flawlessly; but five minutes of probing and error - one real longer milling job and joint error.
I spent hours in front of the HAL scope, just to catch this magic moment. I even had a camera recording it.
Nothing was caught in flagranti.

I now, just for fun, developed a USB to SPI MCU board and started to mod some of the LinuxCNC SPI
code for the 7c81. Not sure yet if isochronous transfer is possible or interrupt transfer would clog everything.
This would be my preferred (notebook) solution.

Which computers are you using for the 7i91? Whenever I browse through all of this here, I only see
10+ years old systems at work (like tommylight’s Thinkpad collection, hehe).
What about a top modern one?

And just to make sure, you all mean PREEMPT-RT, right? Not RTAI.

Make a new config and make sure NOT to check the line where the mouse pointer is.

Help needed - Unable to jog my CNC mill

Category: General LinuxCNC Questions

- It's a gantry machine with a single motor on each axis
- All the connectors are good
- The E-stop turns off and on in LinuxCNC
- Drives are all wired correctly
- Power supply is good
- Yes, I am using the keyboard to try and jog (arrow keys and page up/down) I have also tried the UI buttons (QTdragon UI)
- The preview screen is moving with my keyboard inputs. So LinuxCNC seems to 'think' it is moving.
- I will investigate more this weekend.

If I can move the axis with the arrow buttons under the 'Test this axis' button of the Stepconf setup (which I can) shouldn't they move within Qtdragon?

I have not limit switches set up in the configuration or wired to the breakout board but it seems as if LinuxCNC 'thinks' I'm past a limit and won't let me move.

This is proving difficult to debug. I get the same transaction error regardless of whether the drive is plugged in, however when it is plugged in, it does go into run model. So something is working. It will not however turn back off or respond to M3/m5 commands.

What should i be looking at next?

POSITION_FILE and index

Category: Advanced Configuration

I've written the realtime component I needed. When linuxcnc is started
you can jog the axis and as soon as the index is passed, the position
is corrected using that index. The axis is then also homed.

If the encoder had already seen an index (for example, linuxcnc was
quit and then started again without turning off the encoders) The axis
is homed as soon as the amplifier is enabled.

After homing the distance between the actual position and what was in
the POSITION_FILE is made available on the "offset" pin.

This is tested using a Fanuc encoder which has an index every 65536
increments. This encoder resets the counter by itself as soon as it
encounters the index for the first time since powerup.

I've made the information if the index has been seen available using an
index pin, which is 0 if the index has not been seen and 1 if it has.
The first cycle with index==1 should present the last counter _before_
the reset. (This is how the Fanuc encoder works)

The component can be found at:

Not terrible but not great either

If the PC has a Realtek Ethernet chip you will likely need to install the 8168-DKMS driver

If you don't know the Ethernet chip type you can run this script:
