Linuxcnc getting very slow

I also have such sloweness in my program when the size of it become big. I see such problem at program size biger than 10Mb. Yes, I have old PC.

As for me, I divide my program on the small parts that suits me.
You can use such O-codes: "o<myfile> call" in main program.

What program are you using for generating G-code? Some programs can divide G-code files automatical after making correspondent settings in post processor.

Did you find a solution?
I use linuxcnc to control a 3d printer, and it's not unusual to have prints that last multiple days.
The control software should only load a small portion of the code and dinamically retrieve more code as it runs.
I know that my pc is quite old, but i don't think it's normal that i have to wait 20 minutes to load a program (without backplot) and then having to use a laggy, constantly swapping pc with full ram.




edit: I just discovered that tklinuxcnc GUI actually DOES load the program dinamically. I loaded the program in 10 seconds without any issues.
Can't this behaviour be ported to gmoccapy or axis?

It was my solutins. But new update of linuxcnc - v.2.7.15 looks like loads faster. Have you tried it?

I'm on 2.8 now. However I just ordered the component of my new pc, so i'll test again with a pc with at least enough ram to fit the program and i'll decide what to do.
Dividing the program isn't that easy on a 3d printer, but I guess I could write a script myself if I need it.

I think that the slow part might be the graphical preview.

You could try adding the (AXIS, STOP) magic comment to the files.

(See the Axis GUI documentation for details)

I tryed.
It helps, but i still fill 1GB of RAM and my pc starts swapping.
I'll try again as soon as i receive my new motherboard with 8GB of ram
