It is mentioned in the user's guide manual and in Glade documentation.
And searching the forum will lead to several examples.

It's not easy to answer your question, as it is very global.

I have no recent experience trying to connect to a windows box, so I really have to rely on the experience of others for that side of things.

Mesa Configuration Tool

Category: Configuration Tools

Is there any readme on how to add .bin files for a new board to this? I have the Mesa 7i76eu, successor to the 7i76e, and have downloaded the firmware files from the mesa site but am unsure of how to add them to the configuration tool.

Any help is appreciated,

The problem with Samba from Windows is that Microsoft put some security in place that by default disable Smaba (SMB) connecting with Linux.
The solution is to edit the SMB policy on your windows box and it works perfectly.

-rw-r--r-- 1 root root 248 Jan 25 04:20 /home/maker/linuxcnc/nc_files/examples/ngcgui_lib/utilitysubs/mm_std.ngc

It is there, but it is owned by user root, so it will appear non existent to normal users, in your case maker is the normal user that has no access rights to that file.
No idea why or how, but in general, never use "sudo" unless explicitly told to do so.
You can try to manually set the permissions to read that file and see if that works:
sudo chmod 755 /home/maker/linuxcnc/nc_files/examples/ngcgui_lib/utilitysubs/mm_std.ngc

Help getting NgcGui working on QtDragon

Category: Qtvcp

Hello, I've consulted the following guides:
linuxcnc.org/docs/html/gui/ngcgui.html#ngcgui-ini
linuxcnc.org/docs/html/gui/qtvcp-widgets...cp:widgets:qt-ngcgui

I'm on 
Debian: 6.1.0-30-rt-amd64
linuxcnc-uspace: 1:2.9.4

I've attached my .ini file, and my error linuxcnc.report and a screenshot of the last thing I see before it crashes.

I'm trying to use QtDragon: Utils > NgcGui.
I start by clicking "New Tab."
But when I try to select anything, like "Select Preamble," or "Select Subfile," etc, the program crashes.

I'm thinking it's not finding the subdirectories where these files are located.

But in the [RS274NGC] I have:
SUBROUTINE_PATH = ~/linuxcnc/configs/SaberCNC_10/nc_subroutines:\
~/linuxcnc/nc_files/examples/ngcgui_lib:\
~/linuxcnc/nc_files/examples/ngcgui_lib/utilitysubs:\
~/linuxcnc/nc_files/examples/probe/basic_probe/macros:\
~/linuxcnc/nc_files/examples/remap-subroutines:\
~/linuxcnc/nc_files/examples/ngcgui_lib/remap_lib

I believe the files are there in those directories. Though I also understand some of those are symbolic links, could this be a problem??

To prove the file is there -- for example, the preamble specified in *.ini -- I issue to a terminal:

Nontheless, for example, trying to click "Select Preamble," I was going to guess would choose the
and from a terminal, if I issue:
ls -al ~/linuxcnc/nc_files/examples/ngcgui_lib/utilitysubs/mm_std.ngc

Then I get back:
-rw-r--r-- 1 root root 248 Jan 25 04:20 /home/maker/linuxcnc/nc_files/examples/ngcgui_lib/utilitysubs/mm_std.ngc

Which seems like it's there.

I'm sorry in advance if this is an obvious fix.

Any help would be great.

Thanks again!

Creating pulses through parallel port

Category: General LinuxCNC Questions

From my understanding.
Your stepper speed will be limited by the speed of the thread. Hence the reason for a Parallel port setup has a base thread that runs a far higher frequency.

The thread is running at 1khz, it will take 2 periods of the servo thread to set the Step pin Hi then Lo. eg 500Hz.

Divide 500hz by the Number of steps (200) and you will have, theoretically, 2.5rpm. If using micro steps this will be even lower.

  I will admit I haven't herd of Kanthal wire before. From what I could find online it is an iron chromium aluminum
wire. I would have concerns with a wire that is heated and flexed repeatedly when it contains aluminum . That
would generally be a recipe for stress cracking. Hence why I like NiChrome wire. I would venture a guess that
the wire on your machine usually breaks at the pulley.  Correct?  At least if it's the same as the picture.

With Debian it should install dependencies for a package, if of course you are using a Debian package, if not you are on your own.
The way you are explaining it is what it was like in the1990's installing packages on Redhat & Slackware.
Now if anything "breaks" when trying to connect to anything Microsoft, that's because of Microsoft.
Now something interesting regarding samba. A std install of samba on Debian sets up a share for "home". This is not browsable but can be connected to by using the username on Linuxcnc. The caveat is that you need to create a samba user with the same name, password is easier if you use the same as the Linux password, easier to remember.
To be honest I don't use windows but using the method above I can connect from one Linux machine to a samba share on another with no issues.
There also is another way to create shares that doesn't involve edit the SMB.conf file, but that's for a later date, once I fully understand it I'll do a quick write up.

I'm sorry you're wrong, the current image does support hal_gpio. This has been confirmed by at least 2 users and my own tests.
The config files from byte to bot were strange.
Just did a quick load of hal_gpio GPIO26 loads fine.
Could you please attach your hal and in files using the forum's editor as I think you may have made a typo, as this is usually why pi. Not found error shows up.
I need to get to the bottom of this, if it is an issue with the image it needs to be fixed, if it is a issue with your config that needs to be addressed and the comments you made need to be rectified.
We don't want a bad image nor incorrect comments leading others astray.
Kind Regards
Rob

I think its unlikely that you would need so much DPLL pre-trigger so I don't think
increasinh this timr to 250 usec is going to help

I would check hm2_7i76e.0.packet-error-total to see if you have dropped any packets

You might try plotting the following error and perhaps tuning by adding a little
FF2 (say .0003 to start) to the PID loop (using the calibrate menu so you can do this live)

Also, I considered using the directions at: forum.linuxcnc.org/9-installing-linuxcnc...tall-rtai-got-errors

but when I look at the directory linuxcnc.org/dists/bookworm/2.9-rt/binary-amd64/

I don't see a 2.9.4 version, so I wonder if that is the source of the problems (or maybe just completely unrelated).
