You can try to make a preview window with QtVismach. In Vismach the rotation axis displays well. I quickly made a window that is overlaid on qtdragon , as in the screenshot. You would have to work on displaying the gcode preview, but it would probably be useful.

I'll be hosting a heavily optimized AMD64 Gentoo build for LinuxCNC and I'll be updating my interactive Gentoo installer too, it'll have the 6.12 PREEMPT_RT kernel, XFCE 4.20 pre-release and LXQt 2.1.

Installer works very well, removes all the hassle from building sources, works with LinuxCNC out of the box (just have to emerge it) and the installer works faster than Ubuntu and Debian installers. It's just out-of-date at the moment.

edit: Currently having serious issues with lxqt-panel (the fricken task bar) so it may just have XFCE instead.

edit2: Problems solved, LXQt will be available in this build too.

its fixed now, it was some small potentiometer on the drive that was set to set wrong position and after that it runs super smooth

Hi all, 


I apologize for the delay. I have been busy with this and another project. 

So the new rackrobo does have a way of modulating power output.  I was able to get my hands on a power supply at no cost to me. They are having some issues but it seems like the probability of an issue occurring is still pretty small.  If I do have issues I'll look at swapping the power supply. 

Yes I imagine sinker would draw a lot more power then wire and especially hole drilling. 


As far as linuxCNC control of EDM. Does anyone know if the ones like tommy was showing are using reverse feed rate and short detection?  It seems like it wouldn't be too difficult to pause the program when a short is detected, but does anyone know if it is possible to get reverse feed to pull out of the short and then reengage? I know this is how professional machines operate and I would think someone has figured out how to do this with LinuxCNC...  Any LinuxCNC wizards out there know how to do this?


Best,

Hi,

Years ago i had the same problem as you. Was cutting a Thermal Dynamics 200 Amps + compressor + cnc.
I managed to get a diesel power pack on a trailer.

So if you are like a professor you could manage to create a big iron flywheel in your workshop.
Driven direct drive by a electromotor.

Say the flywheel mass is about 2000kg, rotating at 500 rpm. This will solve power dips for the whole street.
It's a silent & cheap solution.







 

Hi,

So far i am happy with the insights tonight.

Source code:
rtapi_function_loader

Above is a repository testing the posix pthread, running different .so libary functions named "test();".
It's more or less how the original rtapi workflow is.

This is tested ok with a base thread nano second : 25.000
And you can set the used cpu's. You can set it by  passing a cpu_list = {0, 1};

If you load 4 instances of the rtapi_function_loader class and assign each
instance to a different CPU (CPU 1, CPU 2, etc.),
each instance will run on its own dedicated CPU core,
ensuring that all 4 threads run in parallel without sharing CPU time.

We have also a priority for the rtapi_function_loader's pthread in the value 0 up to 100.

Ok, now next thing is maybe to look when, where and why we need to allocate shared memory blocks.
