Good to hear you have a GPU.

You can connect the PC to a wireless router via ethernet and then connect the camera the same router wirelessly.

The PC and camera can communicate via the router without any Wi-Fi card in the PC.


Why not use the desktop for streaming?

I my experience, it is often better to just avoid a problem by going a different route than to actually fix the problem itself.

Hello again!
My next problem to get my machine running (it's running but not as precise as I want it) has to do with two switches.
My tool length sensor is a quite normal mechanical switch, that is NC and put +24V into input-08-not. That's working perfectly.
If I put my 3d Sensor (NPN-NO) into the line as the picture shows, nothing works. The 10k resistor (R1) before the Tool length switch puts the voltage down to 12.xVolts, the Input-08-not is set to "probing" permanently.
The 3D Sensor does nothing at all, not even the LEDs are active (the output is an open collector, I presume). What about diodes?
 

So, my next thought is to disconnect the two sensors from each other and use another Input of my MEsa 7i76e just for the 3D Sensor. This input should not be inverted for correct funktion. How can I do this with or without using an OR2 funktion?
My lines for the tool length are as follows

#---PROBE-IN ---
net probe-in     <=  hm2_7i76e.0.7i76.0.0.input-08-not    
net probe-in     =>  motion.probe-input

AFAIK, I cannot just net another input to motion.probe-input. But how could a OR2 look like?

Thanks for your help, again!

If Step/Dir resistor networks or driver chips are being damaged
it means a voltage considerably outside the 0 to 5V range is being
applied to the Step/Dir pins.

First thing I would check is drive grounding and Step/Dir wiring
Routing step/dir lines parallel to servo motor wiring might also
cause enough EMI to damage the drivers.

An intermittent short to 24V wiring is another possibility.

I did push some work to fix an error I found.

A while ago, my MESA 7i76E broke; one channel just stopped working. I wrote about that here . I then found someone who repaired the card, after which the machine ran fine for half a year. He said he "replaced the resistor network" of the channel.

Today, the exact same issue appeared again. Joint 2 stopped working and after a restart it worked for a minute and went away again. This is exactly the behavior I saw last time.

This time though I was better prepared and had a spare 7i76E ready to replace the other one. After replacing it the machine ran fine - but after an hour the new card displays the same behavior, too! Clearly something is going on that breaks this channel... sometimes.

What would you do to diagnose this? Replace the JMC servo (with the built in controller) and hope for the best?

I remembered there is a wifi PCIe card (different brand) in my desktop which won't be missed. I put it in the CNC computer and now it all works.
I also did a latency test. This is with 5 glxgears plus YouTube running a psychedelic video, plus streaming from my RPi camera. Pretty much the same as I had back in March.

In addition to my machine config described in the first post, my graphics card is a Radeon Firepro V5800. 

Thanks for the comments,
Steve

Can you give more detail of the load problem?
I'm guessing you want it to autoload at startup?

set_style is old code from a slightly different version.
IIRC if you use it then you can't override the style with the style editor.

Here are some of the things you can change from the style sheet editor:

I think it needs a way to change styles per macro as it's hard to get sizes to work with different macros.
If there is interest I can develop it more.

Check the "accessories" submenu for LinuxCNC stuff, sometimes they end up there.

Mesa is definitely the way to go. It "future proofs" your setup. Swapping machines is easy, latency is less of an issue. If your current machine goes "poof" getting back & running is a simple task.

Tho it really depends on your budget....shipping to the Southern Hemisphere is brutal.

The easiest way, to prevent a total rewire is grab a 7i92T and that can plug into your existing parallel port breakout boards (or more correctly the breakout boards cab plug into the 7i92T). That'll get you going, later if you really feel the need a 7i76 can be plugged into the 7i92T.

I'm running a 7i92,7i76, another card for extra Smart Serial ports an analog smart serial card for the spindle and a 7i73 for the pendant.......Hasn't missed a beat in all the years I've been using them. Worked fine on the dual core J3355B system I used for a bit. Asrock J3355B-ITX. Upgraded to a system with a smaller foot print

Regarding isolating cores, from the dark spells I've read it would seem to isolate the cores on the same die, well that was the recommendations for Intel.

Man I definetly need to take some sleep....

 

It definetly did something this time. Thanks for youre help guys. I was ready to just go back to Estlcam and windows haha.

If I go to Applications -> CNC there are only two options there is Documentation and G-Code Quick Reference. There is no LinuxCNC application does that mean somthing went wrong with the installation? I did a restart same thing.

 

Hallo Joe,
ich bin aus München und habe auch ein 4060 mit Parellelport. Wäre sehr interessiert für so ein Treffen. Auch privat zum Austausch, wenn du Interesse hast kannst du mich anschreiben.

Hi Todd,

Thanks for your response — I’ll definitely give that a try, as it feels like my last resort with this current setup.

I've already disabled everything I possibly could in the BIOS. The only things I haven't touched yet are the memory timings and voltages. If this doesn’t work either, I’m honestly not sure what else is left to tweak.

I'm also considering switching to a Mesa card, possibly the 7i76EU, but I have zero experience with Mesa hardware. I’ll need to figure out whether it will work with my three DM542A stepper drivers, and also with my VFD, which is currently controlled over USB using: `loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600`

Things i disabled next to the obvious, like settings for fixed clock speeds (fclock 1066, bclock 1000) disabling power management and disabling hardware that is not being used (BT, Wireless, serial, audio, fancontrol (disabled fixed on 100%)):

BIOS Settings (set to Disabled):

SMT / Hyperthreading
→ Disables logical cores to reduce cache sharing and latency spikes

C1E, C6, and other C-States
→ Prevents the CPU from entering sleep states, ensuring consistent timing

Streaming Stores Control
→ Avoids aggressive memory write optimizations that can disrupt real-time behavior

DRAM Scrub Time
→ Turns off background memory error checking to avoid unexpected memory bus usage

GMI Encryption Control
→ Disables inter-chiplet encryption on Infinity Fabric to reduce overhead and latency

XGMI TXEQ Mode
→ Prevents signal equalization tuning that could introduce instability or variability

DRAM Map Intervention
→ Disables memory remapping logic that can introduce unpredictable latency

DF Sync Flood Propagation
→ Prevents error broadcasts across chiplets, reducing the chance of system-wide stalls

   

 

home and besnik are in the wrong places again and Downloads starts with upper case D. Linux is case sensitive so D and d are not the same.
