In general I lack experience in this stuff, ground loops especially are confusing. I didn't want to ground the 5v negative and create some other issue. According to what I could find online, the floating 5v is fairly normal (switch mode power supply).

Yes the case etc is ground, just 5v is floating.

Thanks pcw, will ground.

If you have the mind of an engineer, why don't you test the software's functionality instead of complaining you don't like the colour?
Its very comprehensive and the probing is first class.

No, once you get a working config stop using pncconf and edit by hand.

possibly but if you follow the updated how to sticky thread (1st post) , we don't use the igh repo anymore.

Is there a way to prevent the .hal file from being overwritten? If you manually edit the .hal file, everything gets overwritten by pncconf. Is there a setting to ensure that only the parts that were actually modified get overwritten in the .hal file?
Thanks,
Hans

So, is it best to ground the 5V and 24V negatives?

Just for safety, and noise I would ground the 5V common.

The Init LED can illuminate for power related issues (check the 5V at the 7I97T)
With power related issues, the Init LED typically blinks.

The other cause of the Init LED being illuminated is because the watchdog
has bitten. This usually indicates either a latency issue with  the host, some
general communication fault or the watchdog timeout set too low in the hal file.

I am configuring my CNC with a 7i97t, but I don't have that problem. I have a Mean Well 5V 10A power supply with a ground connection for the Mesa and the Raspberry Pi 5; the Mesa needs to be grounded near the RJ45 jack, where it is marked "frame ground."

 I'm having an intermittent issue with a Mesa 7I97T on a Raspberry Pi 5. Occasionally CR7 comes on and stays on until I reset the board.The 7I97T is powered by a Mean Well 5V PSU with no earth connection. The 5V negative is floating, and I measure about 100VAC between 5V- and cabinet earth.Does anyone know what specifically causes CR7 to latch on like this? Is there anything in HAL/HostMot2 I can log to find the cause?Also, should the 5V negative normally be bonded to cabinet earth, or left floating?
Thanks all!

Today a question was asked on the forum: why so many gui in linuxcnc?
I always thought that it shouldn't bother anyone because at worst they don't have to use it.
But today I started wondering if this garbage can makes any sense.
Well, I have always been curious what this Qtdragon is and whether it can be useful for something.
Since I always compile linuxcnc from source, I never managed to get this GUI to work.
Recently RuntimeError: module compiled against ABI version 0x1000009 but this version of numpy is 0x2000000...
I can't downgrade numpy to version 1, because I need version 2 for other programs, and besides, apt, together with numpy, wants me to uninstall a dozen or so other packages because they have dependencies.
I downloaded qtdragon from github.com/persei802/QtDragon_hd .
The repository looks fresh, but it's not and it want the old numpy...
Today curiosity got the better of me and I launched Qtdragon with linuxcnc_2.9.10-amd64.hybrid.iso.
Here Qtdragon started up, but my worst suspicions came true.

I simply have the mind of an engineer and I hate "artists" who spoil formally good designs to make them bad but nice...
What's the point of a small gray font on a gray background?
LinuxCNC is not a game that you can run in a dark room and then a dark interface actually makes sense.
LinuxCNC is a machine control that can be dangerous and there is no room for anything "nice".
It is no accident that the e-stop button has a different shape and color than the start button, so as not to look for it and not to confuse it with another one when the machine starts to live its own life...

I know that someone will soon start explaining to me that the authors do it for free and I should be grateful to them.
No, that's not true.
If something works badly or doesn't work at all, there is no reason to be grateful, because why should it?
The rule is simple - if you do something, do it well, and then people will be grateful to you, even if they have to pay for your work...
 

Aqui estão meus arquivos. O encoder está lendo corretamente e o motor funciona em modo de malha aberta, mas quando habilito o controle em malha fechada, o motor começa a vibrar.

Hi Rodw,
have the EtherCAT keys expired?
