If you run LinuxCNC, enable the spindle and set the spindle speed say 1/2 way up, then:

halcmd show all | grep spin

and post the results here, that would help debugging this.
 

Hello together,
another question and problem with my LCNC config.
After solving installation, homing, network, latency problems with your help, I could make the next step and check my spindle output function.
I'm using a chinese 2,2kW standard spindle with a Hitachi WJ200 VFD, parameters set with Hitachi proDrive, the FWD/Stop control is working correctly, but I cannot measure any volts at the Spindle Output of my 7i76e TB4. The electronic pot gets 10V from an external voltage source, these 10V are measureable at TB4, Pin 3.
Im using Probe Basiv V.5 under Debian 12 and LCNC 2.9.3. on a Lenovo Think Centre M92p Tiny, 8 GB i5 2900 GHz.
I set the output with MDI S6000 and can see, that spindle-out goes to 100 (rps), Spindle-enable goes on, but I can not see any voltage at Pin 3.
Do you have any idea what is going wrong here?

Wiring:
8 Dir + STP (Hitachi WJ200 D2)
7 Dir - GND
6 En + STA  (Hitachi WJ200 D1)
5 En - GND
4 nc
3 SPI + +10V external voltage
2 SPI OUTPUT  -> Analog In O
1 SPI -       -> GND, L


INI:
MAX_OUTPUT = 24000.0
OUTPUT_SCALE = 24000
OUTPUT_MIN_LIMIT =  1000
OUTPUT_MAX_LIMIT = 24000

Thank you for any help!

The first problem is real time issues with the network interface.

To get a rough idea where things are, can you run these two commands and reply with the results:

sudo chrt 99 ping -i .001 -c 60000 -q 10.10.10.10

This will run for 1 minute and print statistics
(replace 10.10.10.10 with 192.168.1.121 if that's the 7I76Es address)

lspci | grep -i eth

(this should make it possible to determine the PCs Ethernet interface type)

Hello guys,
bad news for me.
Today i installed the VFD to the wall a bit far away from the control box. After i was done, i wanted to check if everything works and check if i still have some noise problems from the VFD. 
Due to the fact that i am again totally confused from 5-6hours of trying to fix it, i am not anymore sure if i got the unexpected real time delay on first start up (but later i got it all the time), but i have found out that when i jog by keyboard or mouseclick on the jog buttons quickly, lets say couple of short and quick jogs, then i get a joint following error 0 and the machine is then off. When i put it on and do the same quick and short jogs then i get following error 1. Then again the same and following error 2. (i would not take the sequence serious, i later also got following error 1 first, at least i believe, but i am not 100% sure)
I GET NO FOLLOWING ERROR WHEN:
- Jogging normalny, no quick clicks
- running a program

Is it possible that USB is the problem?
I havent changed anything since i posted the screenshot of the very-good latency in latency-histogram.

More info:
It happens also that when i want to start Linuxcnc i get a error (see picture), but its possible that it starts after trying second or third time.
Also sometimes Linuxcnc got stuck (freeze) or the whole PC, but of course i started to play around with the Bios settings and specific bios settings could create more problem.

I dont have PS/2 keyboard / mouse available to test. Changing two USB settings in BIOS did not help. (legacy usb something and one other option)

So, if you will have no idea, then my only option might be the 7i76eu, BUT i am also thinking to go back to Wheezy and Linuxcnc 2.8, IF its possible to do file sharing with e.g. Samba, but i believe that all tutorials are before windows did something to block the file sharing. Rodw wrote something about it, here in this thread.
PS: I need nothing but working Linuxcnc, mousepad/geany and file sharing or a browser that works so i can send files by mail or open Microsoft OneDrive.


 

Could StepGen be used to convert the absolute position data from the Fanuc encoder channels to quadrature pulses for outputting to encoder input on the drives? 

I have been using a very old Plasmac version from 2019 and although I alway planned to upgrade it, it just worked so got put off. A month or so ago I turned on my plasma only to find the hard drive had failed. I fitted a new ssd and did a build of QtPlasmac with Debian 12 bookworm. Although I got the machine working as such, I have a couple of issues that I am stuck on;

Using the same PC I used previously without issue, I now regularly get errors like 

“Mon24 13:59: Unexpected realtime delay on task 0 with period 1500000
This Message will only display once per session.
Run the Latency Test and resolve before continuing.
Mon24 13:59: hm2/hm2_7i76e.0: Watchdog has bit! (set the .has-bit pin to False to resume)
Mon24 13:59: hm2/hm2_7i76e.0: Smart Serial port 0: DoIt not cleared from previous servo thread. Servo thread rate probably too fast. This message will not be repeated, but the hm2_7i76e.0.sserial.0.fault-count pin will indicate if this is happening frequently.”

I have tried the period setting at 1000000, 1500000, 2000000 etc latency test is around 35000. 



the other major issue is that I can’t cut anything that has an arc unless I use the QtPlasmac conversational. My sheetcam produced code just generates errors like

--- QtVCP Screen Started on: Mon, Feb 24 2025 13:12:29 ---

I have ensured G91.1 is active and all the holes entries are # out in the nc file. 

Can anyone point me in the right direction? I can provide any extra info needed


 

i am not sure whether this is a hal issue or an issue with qtdragon_hd.  
i have just installed 2.9 the newest build,
and rebuilt my machine.  on my old machine the esop on the screen and the physical estop worked independantly.  
now the estop on the screen only reflects the physical button.    may be this is the way it is ment to work and i just had somthing different. 
i liked it as i get the button on the oppiset side form the screen and i had an estop on both sides of the machine.
 

This is cool, I have Mesa CT making a working configuration for the 7i76EU now. Just need to add the spindle types.



Thanks PCW
JT

Update:
The machines works again, without unexpected real time delay and a very good latency, but i had to take the PC of my Lathe. (the lathe machine uses the Mesa 7i76e card)
That PC has a on-board graphic card, but i first tested it with the VGA that was already there and i got the same latency issues. As soon as i used the on-board vga, the latency was perfect and no "realtime errors" at start up.

I have started latency-histogram, with 4 x glxgears and a youtube video running for about 1 hour.
I first started the histogram, then opened one glxgears and waited to check if anything spikes happen. Then i opened 3 more glxgears. No latency spike. Then the youtube video and the pc was running like that for almost one hour without any change to the base thread.
On tomorrow i will run a milling program and check if anything bad happens.

Also i will connect that "latency issue PC" to the Lathe and hope there will be no problems, but i think with the Mesa card there shouldnt be any.

Perfect! Not sure what plasma cutter you have but if it was say hypertherm, a surface mount circular connector that just pushes into the socket on the machine and you would have a nice complete self mounting package. I used the 7i76e spindle relay for torch on so there is nothing wrong with your photo diode. You just need to add a pull down resistor on the arcOK as discussed in the qtplasmac docs. 

Of course if you had a XPR hi def its Ethercat anyway!
