Is this linuxcnc 2.9?

Hi Guys,
The Maho has been out of service/ limited service for a couple of months while I gave procrastination and denial a chance to solve it's problems...


Cheers,
Mark

Hi - The 7i77D has been out of stock for a spell - anybody know if they are going to continue this version. Im tempted to use a 7i77 with relays but if the D sinking outputs is going to become available Ill hang on.
Thanks all for a great service on this forum. Good bedtime reading

As far as I know it shouldn't matter if you install it during compilation, otherwise it would be fixed with "apt reinstall linuxcnc-uspace".
What do you see with: uname -a ?
What do you see in the terminal when you start with: latency-histogram ?

Without seeing (uart) logs it's hard to tell what's going wrong.

With the 6.6 kernel likely you didn't remove the localversion part from the patch like I mentioned before. Probably you can also remove it from the kernel config menu.

If it's something else, you should provide logs
 

Yes, for kernel 6.6 it was the localversion indeed, I forgot about it
but for bot kernels 6.12 and 6.6, when I tested the latency-test I got 0 for all of it parameters!!
(kernel 6.6 with rt patch from kernel.org and 6.12 with rt patch that you gave its link)
btw I installed linuxcnc using custompatch.sh file to be installed during the compilation, can it be the problem for this?

Yeah quite out of the original topic. Maybe there could be a generic consumable thread?

Might sound far fetched but it is true. You will have a molten puddle, bead or what ever you want to call it, in the “root” of the arc. You try to constrain and keep it as steady as you can. The copper ( or silver) around the hafnium/tungsten gives means to conduct heat and electricity.

Of course in the old stuff you didn’t have anything “fancy”. You had plasma with electrodes made of tig rods. When the electrode wore, you could pull more from the torch.

I think it was in the -90’s where hypertherm came out with venting. So you don’t only ramp down the current but you match it to the flow rate of the plasma gas at the end of the cut. So you have a separate valve (close to the torch) that lets out the plasma gas. You then see how fast it gets rid of the plasma gas and you ramp down at the same time and rate. This improves the consumable life significantly.

There is quite a lot of cool stuff behind the “scenes” the more complex the systems get.

I am way to far, but if someone comes from there, i might just do something as i am sure i have 2 of 7i92M and 2 of i have no idea 7i92H or 7i92TH.
Mailing would cost an arm and a leg as i am in Kosovo, still.
Free of charge as much as humanly possible as i can use the T ones easily.
I will check with my brothers and friends if i can arrange something, but nothing fast, that is for sure.

It's a ratio. units of skew in Y  per unit of travel in X. If you set 'skew-y' to 0.1 then moving the y-axis in the positive direction will have the x-axis move 0.1 units in the negative direction for every unit of y-travel.

 

It can not find axis number 3, but it does continue loading...

Hope this helps.
