Advanced Search

Hello i am pretty new with linux and aslo with linuxcnc, i know the basic things about programing, i can do that a scara can move into my control board, but i have a question, moving the joints it moves correctrly that the screen says, but when i try to move on world mode, on x it mad kind of well but made like a reallly big circule, but on y made a small circule that not move on the right axis, and i have to but on these order X Y Z C , i have to use the C axis to the rotatory becuase if i use the A it dont move and start to do more strange things.

can somebody help or have any idea about that issue i am using the last linuxcnc and the scarakins, now im trying to do an personal scara kinematics but i have some library errors.

Hi all.

As I write this I'm suddenly uncertain whether it counts as a poor use of AI; in any case, I asked the chatGPT 4o for a mod and the result appears to work. I wanted better file search abilities since lcnc's default behaviour means it takes a lot of clicks and scrolling for me to find the files I want to run - particularly 'last modified' sorting.

Do sudo apt-get install zenity,

Follow BigJohnT's instructions regarding bigfileopen.tcl

Then use the attached as your bigfileopen.tcl (copy it in to your config folder and change the extension)

This calls the zenity app on using file Open within Axis. It should default to the Desktop the first time, then to the last folder used. Hope it's some use.

I just tried to create a config in pncconf for a 7i97t and I encountered an error.
Attached is a pic of the error.
I am a novice so I may be doing something wrong, I am barely sure I updated to 2.10.
 

I played with 1704 on my servos and you have to have every single fixed pdo matching in your xml. if you accidentally have an extra one, or one less, or a wrong one that's not in the fixed pdo, it wont work.

Looks like there is more support for Mesa than I was aware of.
linuxcnc.org/docs/2.9/html/drivers/mesa_...us.html#_quick_start

But it still looks more complicated than using USB.

Using the USB dongle is much simpler and uses supported drivers that are included with Linuxcnc.

Using the Mesa board for controlling an RS485 device is more involved. Someone please correct me if I'm wrong, but I thought that you would be required to a custom firmware that would then need a custom modified Linux driver that supports your specific RS485 device (each device implements Modbus control differently.) There is very little if any documented support for this using Mesa. I've only read a few threads where people were wanting to try this, but I don't think I've seen any posts declaring success, let alone instructions.
