The forum is really laggy recently.

Category: Forum Questions

Yes it does.Always stuck at the same place when using wget.
A bit random speed though. Sometimes very slow, like a minute and sometimes fast.
Going langdons route to the forum follows the same overall speed, but as of now is always faster.
And fetching using http is always much faster than using https, however only some static stuff like logos
can be fetched using http.
That points to the TLS handshake being the cause of delays.

But, as fun as it is to try to diagnose this from remote and coming up with temporary solutions like langdons url redirect,
it must be possible to check the website hosting the forum.
Surely someone, somewhere, hopefully the admins, knows how to have the website checked.
Right?

Sorry I can not really help, but searching for infos on my Baruffaldi RH80 I found some infos in the internet that can at least help to identify Baruffaldi toolchangers and show some of the interior, nothing to technical- just pictures of a brochure. But might be potentially helpful for anyone searching for infos on his Baruffaldi TC:

In summary the OP is added the host linuxcnc.langdonstaab.ca to DNS records, the same process I had to go through when running my own server for hosting the early Linuxcnc Mint ISO's I created. So when using linuxcnc.langdonstaab.ca you are connecting to an unknown server serving out forum pages.
Whether or not you can login with your username using a password that is not associated to your account at forum.linuxcnc.org is unknown. If it is possible to do that, I'm not even going to try because I have zero trust in the OP's setup, is unknown, but if it is possible it could be one enormous phishing scam.
Whilst he has made enough posts to get Platinum member, there by adding some trust, I can not recall actually having given any advice that is proper.
If he has no nefarious intent I still would be wondering about security and such.

Yeah it may sound crazy, but hopefully I've proven that the OP has not done anything to do with DNS.

As I mentioned. First I am trying to test it with a4988/drv8825 drivers. That's why I didn't loaded tmc5160 modules. Testing it in step/dir mode only

Hi, LinuxCNC is very capable of handling this configuration with 4 joints and a X Y Y Z configuration. Check out the config below for my 3D printer that has dual Z axes.

github.com/scottalford75/Remora/tree/mai...figSamples/hypercube

The two joints won't jog together until they have been homed. I've found that out the hard way...

Cloudflare caches content of websites proxied through it.

That could explain the speedup.

Also, Cloudflare DNS is probably faster than whatever DNS the forum normally uses.

The speedup is almost certainly multifactorial.

Keep in mind that I didn't expect this to work, or even improve anything, I just added an A record to the forum because I already own a domain, I already have a Cloudflare account, so I tried adding an A recor nd for the forum because it might work, and it did.

If you are worried that linuxcnc.langdonstaab.ca is out to steal your data for some reason, don't use it.

You can use forum.linuxcnc.org, or the direct IP, if you like.

I will not attempt to list my alternate link on Google, because it is not official, it's just an alternate Cloudflare route to the forum.

If you are suspicious, create a free cloudflare account, connect it to a domain, and do exactly what I say I did, and see what happens, you will get the same result as me.

If you do not believe that the IP address of linuxcnc.langdonstaab.ca is actually a Cloudflare IP, check bgp.he.net.

PnCconf Mesa 7i96s PWM speed control OUTPUT_SCALE

Category: Driver Boards

Yes, but the pncconf spindle setup also works with other devices with fixed 10V or +-10V  full scale
(7I77,7I76,7I83 etc)

It really should have an additional field for potentiometer type outputs based on the card type
Maybe "Full Scale Analog Output" and "Voltage For Maximum RPM" or some such

Thanks PCW! The quick reply saved me much head scratching. I will admit that I find this area of the setup a little confusing. Isn't the Mesa 'Spindle Out' voltage fully defined by the input Spindle+ and Spindle- values? Given a potentiometer wiper can never have a voltage higher than its input, what is the need for specifying the 'analog Max Voltage' at all?

Yeah I've seen it before, I believe it's a bug with the version of Mesa you're using.
Compiling a new version of mesa with panfrost would likely solve it.
Otherwise I'd suggest to take a new Armbian image and install the 6.1.115 kernel from: drive.google.com/drive/folders/1sPtbXDfx...WCB8o-ur0CINmMNvcjTQ

With the overlay "opi5plus-fixedfreq-undervolt.dts" it has a very low latency. You only need to remove the "-plus" at comparability and after that install it with "sudo armbian-add-overlay opi5plus-fixedfreq-undervolt.dts"

Its because pncconf assumes that the PWM full scale is always 10V so if you specify 5V
Is sets the scaling so that you would get 5V (1/2 of full scale scale) at 18000 RPM.

Just leave the "analog Max Voltage" at its default 10V

I'm setting up my machine and 7i96s using PnCconf and have had some issues with the spindle speed control. My VFD expects an analog 0-5v signal for speed control, i.e. 0v stopped, 5v 18000 RPM. It is open-loop, no spindle encoders. The motor has 2 poles and the drive frequency at 18000 RPM is 300 Hz. When I generate my .ini and .hal files with PnCconf I get the following in my .ini file.
[SPINDLE_0]
P = 0.0
I = 0.0
D = 0.0
FF0 = 1.0
FF1 = 0.0
FF2 = 0.0
BIAS = 0.0
DEADBAND = 0.0
MAX_OUTPUT = 18000.0
OUTPUT_SCALE = 36000
OUTPUT_MIN_LIMIT = 0
OUTPUT_MAX_LIMIT = 18000

With these settings, when I specify a speed of 18000 RPM (M3 S18000), I'm seeing less than 200 Hz on the VFD display and the spindle seems slower than I expect. Looking through the forums, I see most examples have OUTPUT_SCALE=MAX_OUTPUT. Sure enough, when I change the .ini file and set OUTPUT_SCALE = 18000, and command the spindle with M3 S18000 I get 300 Hz on the VFD display and a higher speed at the spindle. Can anyone explain what is going on here? Have I done something foolish? Any ideas on why OUTPUT_SCALE is configured as 36000 in PnCconf?

Hello everyone,
I installed linuxcnc 2.10 on orange pi5 - with armbian + rt-kernel 6.1.75. The system was made a year ago, and I installed linuxcnc 2.10 now with old versions of dependencies, to keep the 3D acceleration functional.
The problem is that at startup I get the error:
python3: ../src/mesa/state_tracker/st_texture.c:73: st_texture_create: Assertion `height0 > 0' failed.
/usr/bin/linuxcnc: line 1005: 24283 Aborted $EMCDISPLAY -ini "$INIFILE" $EMCDISPLAYARGS "${EXTRA_ARGS[@]}"
Does anyone have an idea if it's a bug in linuxcnc, or the error appears as a result of a conflict?
