I would guess you changed the IP on the PC ....
That error is almost always due to PC having the IP set at 10.10.10.10 (or 192.168.1.121), set it to anything else for the last 2 (or 3) digits:
10.10.10.11 is fine
192.168.1.100 is fine
etc.
Edit:
check with
ip a

so working away and everything is going great, until. went to cut some plate today for the air scribe, turn everything on and then, she no connect. Worked fine a few days ago.

This is the error and i can't find a fix. Help

Hello.
I hope it's ok if i use this Thread for my questions. I've the same machine with same hardware (Turret, Encoder, Heldt&Rossi, Baumüller, Sinumerik etc.) and doing actually the retrofit with 7i97t and 7i84u.
My first question is... I need a enable signal for X and Z on the Heldt&Rossi amplifiers. (see picture)
I would connect PIN 19 to ENA0+ and PIN 10 to ENA0- on the 7i97t. Am I right that this would work?

I would do this a but differently
Let the mains power come in and use some DIN rail terminals from Ocean controls. They have some Bus bar connectors to join a few together so that are all common. you'll need some green earth terminals as well
Grab something like this industrial power point but seperate the two pieces and flush mount to your enclosuere
www.tropac.com.au/10-AMP-250V-3-Flat-Pin-Switched-Socket
Use the switch as your main power switch and the power point for your router. Put a household breaker on a Din rail for circuit protection
So now you need to switch your router from your 7i96s.
You could use a Jaycar SSR (you also need the heat sink on this page)
www.jaycar.com.au/solid-state-relay-4-32...a-switching/p/SY4084
Or you could use a contractor from tropac but make sure it will switch with 24v DC (some are AC), you may end up with a 3 phase one
www.tropac.com.au/search?keywords=contactor
Between your mains power and the 7i96s, use an EMI filter www.jaycar.com.au/240v-ac-emi-filter/p/MS4001. Then run the mains power to your 5v and 24v power and 36 volt power.
For your estop, Jaycar's one has  1 x NO and 1 x NC contactor. set it up so that the NO side switches 24v to an input and the NC side is on the mains power to your stepper motor supply and your router power point. The goal is that hitting estop will turn the router off and disable motion. We also want to send a signal back to the 7i96s so it knows estop has been pressed. the 7i96s will be powered on all the time.

Hope you have followed thaf!


 

Good afternoon Rod,

Thank you for your guidance and instructions. I am very overwhelmed... I am going to study the solutions suggested by tommylight and Rob ( unknown ), I feel comfortable because they are simpler than this. As my knowledge progresses, might be I can take on this solution.

My friends are all programmers, none of them know electronics. I can only ask questions online, and study using online resources. I find that it is hard for me to get through some issues.

Thank you and best regards,

...behai.
 

Installed the THCAD2 and to no ones surprise, it works!
No evidence of the deed though, sorry.

You are welcomed, always.
And thank you for sticking with us, you are here for a long time, looooong ...

I recently found this thread and am extremely grateful for all the work on getting NativeCam working once again !!

I have not upgraded my linuxcnc in years because I didn't want to loose NativeCam.

I have a spare computer that I will install Linuxcnc 2.9.4 using the live ISO on tomorrow and NativeCam using the instructions posted last.

I will report back and Thanks once again !!!

yes the one i am using has an index pulse!

That many posts, and you do good if you don't have any mess-ups!
A big THANK YOU! tommylight for all the input to LinuxCNC!

Thanks for the input!
I used 20:1 on the Hypertherm Powermax 85 and F/32 on the THAD-10.
I switched from 50:1 and F/1 settings, but I did not notice any substantial difference.
I just finally updated my CNC Plasma table from PlasmaC to QtPlasmaC.
It's been on the to do list for a very long time and I finally got it done. So far I like the update, sometimes it pays to stop, and "sharpen the axe"!
My Hypertherm Powermax 85 had been giving a service code and needed repair. It took a replacement main circuit board.
Hypertherm plasma cutters have served me well. I have been using this one for a lot of cutting since 2014.

 

Link on the original post updated with the new version with 6.13 RT kernel.

For someone that has several machines with touchscreens, maybe i was a bit quick on the draw, but i always have keyboards on them so i never though about it.
Valid reason, thank you for pointing it out.

This is where i started back then, although i can not find a recent version of it not the exact one i used, but i had this printed and on my desk at all times for months
linuxcnc.org/docs/2.6/pdf/LinuxCNC_Integrator_Manual.pdf
The exact procedure was, i downloaded the 6.04 or 8.04 ISO, installed it, used the stepconf wizard, powered on the machine and it happily engraved EMC2 (that was LinuxCNC back then) on the table, albeit mirrored, so a bit of reading and found out i can edit the hal file and just add minus sign to scale to reverse the offending motor, opened the hal file and had a quick glance for about 10 seconds where my brain went boom thinking this is just like wiring stuff with wires!
Love at first edit.

Does your encoder have index?

I use it quite often, for example drilling a number of holes, I can just enter the list of G83 positions in MDI.

Editing a file with a touchscreen and no keyboard isn't something I want to do, but entering a bunch of MDI commands in the Touchy MDI interface is easy.

And I am far from convinced that there is any applicable standard that prohibits MDI queueing.
