Hi, I was curious if there is a way to reconnect to mesa card without restarting linuxCNC. Sometimes i turn my cnc machine off without quitting linuxCNC. It throws a hm2read error as it has lost the connection. But i cannot establish connection without restarting linuxcnc.

I've tried entering initialization line on my main hal file going "hm2_eth board_ip= ......."
also mesaflash with --reload argument

Hey guys! 

[TL DR] Has anyone used one of the PCIe to PCI adapters? do they work? what one did you use? 

First post here so apologies for annoying newbie post and most likely more posts in the future.
I've looked around to see if this question has been asked but couldn't find it (Again sorry if it has and I've missed it)

and before someone says to get a MESA card, I am open to the Idea at some point but at the moment I can't afford it especially when converted to Australian dollars plus shipping and import fees its almost $560 so at the moment its out of my price range.
 

Here is one with both, PCIe to PCI adapter and mesa 5i25. And a PCIe riser cable.
 

The adapter looks like this: www.amazon.com/StarTech-com-PCI-Express-...d/dp/B0024CV3SA?th=1 I don't remember the exact model and shop but the price was like $10, cheap anyway about 2 years ago. Tested with a PCI parallel port card and it worked too.

The pc in the image is an Asrock J1900B-ITX but I have changed it later to a WADE-8012, so both are quite old. Reason for this setup is that I wanted to use the 5i25 (+7i76) when the old pc died...

As tommylight said, the only way to be sure is to test.

That library only implements line-to-line bi-clothoids from the paper. They only have a starting and ending angle because the curvature on the ends is zero to match a line's curvature. You also need the line-to-arc and arc-to-arc variations. Those are more complex to solve because there are more constraints. The clothoid needs to match the angle as well as the curvature of the arc at the point it joins.

You wouldn't fit the clothoid iteratively over the arc like that though, you use them to blend the joint's between lines to arcs, and arcs to arcs. The arc is already curvature continuous over itself, so there's no need to mess with it beyond whats needed for blending.

The s-curve solver I've been working on is almost done. Right now it averages 5700ns per solution on my PC. I'm not sure how that compares with other methods. I've mostly been spending time fixing corner cases where the precision is lower by having it solve billions of randomly generated problems until it detects something go wrong, then investigate and fix. The paper I was reading also didn't actually address the case where it isn't possible to reach the requested final velocity given the path length and initial velocity, so I had to figure that part out, but its working now.

I don't know how you're actually solving the s-curves now. But I imagine you must be projecting the 3d path and constraints down to one dimension and then solving right?

Hi,everyone ,is there any way to customize the language of the QtDragon's interface,e.g I want to make it to Chinese,such as button text,how to make it ?Appreciate for any comments.Thanks .

I want to control stepper motor using linuxcnc, using a4988 driver. IS it possible?

It seems that this is an issue on g-code files that use temporary materials.
We will get a fix out as soon as possible.

Edit: A fix has been pushed.
 

You could make a 'filter' program to remove the U and V automatically before loading the program.
linuxcnc.org/docs/devel/html/gui/filter-programs.html

Are you using qtdragon or qtdragon_hd?
Can you run from a terminal to see debug info.
What happens when you push any of the home buttons?

I made a sim for xyyzw and it seems to work for qtdragon.

Please answer the questions explicitly.
Did you home the machine?

You don't need home switches or limits switches or a real machine to home the machine.
Homing sets the reference for the machine origin which sets the soft limits.

If you didn't home - the machine doesn't know where it is.

Managed to figure this out - I have independent X,Y,U and V working now. If anyone wants the config files, let me be more helpful than the forum was

Pardon the second post for further details. Opened the editor and it lost all post formatting, so I backed out cautiously.

If I dismiss this error then try clearing or Reloading the file, I get another popup with the message shown below. QtPlasmaC then becomes unusable. Can't jog machine, can't cycle start, can't clear file, can't reload, can't do anything. Only recourse is to close and launch LinuxCNC and start over.

Greetings,

My trusty computer died, I rebuilt on a Bookworm-based machine, and installed Linuxcnc-uspace master from buildbot2.highlab.com.

Now in any file, if I click somewhere on the drawing to do Run From Line, after hitting ok in the dialog that pops up (from here to end option) then I get this notice.QtPlasmaC version 2.10-008.044

Let me know if you need any of my config backups or more detail in order to reproduce. I've tried on various ngc files, all with the same result.

You may add the QQ group 251676794 if you know Chinese.They are all kind people who may help you with your problem.

I just tested Axis sim mm, it does not exceed limits, so how are you able to exceed them?

There are no limit switches, I'm in Sim mode presently.  So over travel should not be possible. 

So isn't the Min_Limit and Max_Limit the travel limits, and not fault limits?
