i installed new version 2.9.4 and have problem, old 2.8.4 working well and no problems, now i have big problems, if i try open new G-code in ro linuxcnc "open code", then search file location windows go all time black screen and go back to login site. same than has boot all computer, why. same this doing if i try open code come black screen and then go back to open file location first 1-2 time and 3 time go main login screen and has closed all linuxcnc and computer.
but if i open g:code  not search rows what file and were have what open, only click open no problem and open code and run cnc good, but if open search rows were file have come all time black screen and go back to main login site again and all softwares has closed, 
sorry my english not can tell better what is problem. same if open linuxcnc sometime screen stay blinking wrong and any buttons not can use, need end linuxcnc software and open again then no blinkink screen and can use normal. blinking mean all pictures blink some have normal some black and display blink ad shake.

In a terminal enter:

halcmd show pin <PIN NAME>

you could try something this:
linuxcnc.org/docs/devel/html/gui/gstat.h...mponent_code_pattern

but use the message 's-code-changed'

Many thanks. I'll give it a go.

Gray is OK, the rest is not, and it is all over the ini file.

Rod,
I might have explained things a bit poorly when I talked about the axis 'catching up'.

It's not how fast LinuxCNC itself responds, its the fact that axis motion commanded via hal pin isn't added to the queue. This means that if the rotary axis cannot move fast enough at a sharp corner, the other axes will not slow down in proportion. To compensate, you would have to feed slowly at all locations or write a program/post which implements smooth changes to slower speeds at corners.

I've had this issue using external offsets to simulate coordinated motion for surface mapping. This isn't a criticism of external offsets, it's just not the most ideal tool for that purpose if your X and Y axes are faster than the Z axis compensation is. This is because a standard implementation is commanding the Z offset using a hal pin corresponding to the current XY position, so you need to slow down at all positions to guarantee an acceptable Z positional tolerance. A tangential rotary axis will definitely suffer from this type of issue on sharp corners.

I understand what you're saying, and modularity is the aim for LinuxCNC, but surely since this tangential rotary axis I'm describing is ideally in coordinated motion with the other axes, it makes sense for it to be directly controlled by the trajectory planner? And especially since I'm describing a case where the tangential angle is both generated by and used by the trajectory planner?

The trajectory planner already directly commands axes, so allowing it to slave a rotary axis to an attribute of the linear axes calculated by itself could make sense.

Also, please ignore some of my thoughts above about how the rotary axis might also be commanded with G-Code as well, I admit I got a bit carried away thinking about a more complex implementation before settling the basics. I just wanted to argue that there are benefits to this approach.

And, sorry if I've gone a bit off-topic for the core trajectory planner discussion, this is discussion of a hypothetical feature after all! Happy to carry on discussing this somewhere else!

I believe the last time I've tried one wch card, the i/o pins were disabled.

But just now I am reading how to use setpci to enable them:

tldp.org/HOWTO/Serial-HOWTO-8.html#pci_enabled
wiki.osdev.org/PCI#Command_Register

I had no idea what those flags from lspci -vv mean. Now I am starting to figure it out.

I'll give it a try. I still have some wch cards. Maybe now I can make them work (knowing what I am doing)

Pretty sure I've had the PCIe working.
The PCI one I've used with a Xilinx Parallel Port Programmer, very slow as it really needs EPP or better.

When you say you can't get the WCH to work, do you mean no signals at the pins ?

I might be able to do a quick test just with the Parallel Port tester with a breakout board connected.

Point 22 refers to eee for intel
Disable energy efficient ethernet. Add this to kernel parameters with isolcpus
igb.EEE=0

Sorry,the document is a bit haphazard as I kept adding stuff as I found it.

Thank you. I'll give this a try.
Would you consider making the corrections to the files or commenting on what things don't belong there? If not I understand. I'll let you know how this works out.

Thanks

From the ini file:should be JOINT and should be 5
and...............
Why so many
DISPLAY_JOINT = 4
DISPLAY_JOINT_NAME = A
[GEOMETRY]
AXIS_A_JOINT = 4
AXIS_A_TYPE = ROTARY
AXIS_A_LENGTH = 30

DEFAULT_LINEAR_VELOCITY = 36
MAX_LINEAR_VELOCITY = 4.00
AXIS_A_JOINT = 4

I have no idea how this is starting, to many things that should not be there.
The ONLY things to change, after adding the 4th axis, are Display if it does not show how you want in the GUI, and TRAJ section.

The asm1083 is a PCIe to PCI bridge. The other chip would be the chip with the parallel etc functions.
Photos are ok, but the real bit of important info is the PCI ID number.

If you look at the text file I attached a couple of posts ago as well as having info regarding the parallel port cards it also has a couple of commands as where to get the info from the file system. Like what mode the card supports and stuff like that.

That's a great idea! Much more meaningful info than a screenshot.

I think we can make your file format a tempate for this topic. I will update my posts to match your idea.

By the way, how have you managed to setup these wch chipsets to work? It there some special trick? I have never been able to make them work.

OK, thank you, i am a bit fuzzy today on everything due to lack of sleep and some other "issues".

Don't worry!

Btw, my 4 yo daughter just loves your profile picture xD

Thank you.  Here they are.
