There’s no rt serial port driver, Andy mentioned this a week or 2 ago. I think he may of mentioned it could be a good idea, but of course it would have to be a hardware port not a USB one.

ScotA has done a lot of testing but no idea of the current state, he's not much here lately.
I have built over 10 Vorons by now, i have 5 Voron 2.4R2, 3 of those use linear rods on Y and Z instead of linear rails, so i can provide ready made stl's for 8, 10 and 12mm rods, if i can find them.
As for Marlin vs Klipper vs LinuxCNC:
The good:
LinuxCNC = reliability, flexibility, use as you like/need/want
Marlin = runs on arduino Mega, can resume after power failure, quite reliable, SD card support, easy to use
Klipper = tailored for 3D printers, Telegram for monitoring
The bad:
LinuxCNC = no pressure advance
Marlin = very limited user control, any mistake=restart print, not easy to set up for new users, any configuration change requires flashing the controller
Klipper = very limited user control despite many adjustments, very high overhead/bloated, knows to mess up on it's own, not easy to set up for new users, very hard to set up and test and verify a DIY 3d printer for new users

Honestly you’ll probably see more USB flash failures than SSD failures.

Random boot failures would point to a hardware issue, check your cables. Or try a different sata port. And stay away from $5 chinesium SSDs.



One thing you can do is mount via fstab a USB flash drive as your home directory on a normal install.
Or just keep a backup of your home directory.

Quite a while back this was very easy, now i have no idea as i have no need for it anymore, but important search terms for google should be

Mind the date of the results, the old ones will most probably not work.

That is very true.

  So I have been 3D printing off and on some last year and a ton this year . Where I work we have a Bambu Carbon X-1
(soon to be two)  and a Prusa Mini, and of course now I am playing around with my foam cutter, soon to be running under
Marlin control  instead of just GRBL. I am considering in the near future building my own 3D printer i.e. a Voron not sure
of model yet. I have some questions though,  most use Klipper as the control software.
Has anyone done a straight up LinuxCNC version?
If so how did it compare to Klipper or Marlin?
Anything to be aware of other then a long list of extra coding for temp. control and the like?
 

From Live setup I'm referring to using USB disk, and not using harddisk or SSD to avoid failures and random boot failures. I got this thought because I faced several problems in boot corruption and ending up into whole new setup or may be re configuration.

Thanks

Hello everyone,

Sorry in advance for posting dumb idea. I was wondering if we can make live setup for configured machine which boots and loads machine configuration and that configuration don't get corrupt with any malfunction or tempering to setup files. When machine boots it loads original configuration by default.

Is this good idea? Is it possible? Any possibile problem?

Thanks in advance

Ich bin im programm rumgefahren sodas es verschwindet es ist in der konsole nichts mehr passiert oder habe ich etwas falsch gemacht?

I know the older ISEL controllers that had the slide-in modules. There was a step/direction module for those that replaced the controller module so you could run the machine over a parallel port. The newer controllers had everything integrated on a single board so that had to be scrapped for new motor drivers and a breakout bob.

When I was working with the Mesa firmware when using SPI wiring from the Pi to the dev board needed to be good. On the design of the board for SPI interface I designed to have a gnd between every signal. Since I’m using a different dev board I’m being a bit, okay really, lazy.
Considering a slight redesign of the board that brings out 3.3v and 5v on the connector that has the spi connector. That of course will be future Rob’s decision.

Whenever I see:

CANNOT FIND MAILBOX

This is because the RTAI kernel image and the modules are not built against each other. The RTAI modules package must be built against the RTAI kernel you wish to use. If you mix and match, you will run into problems.

If TCL/Tk is seg faulting, I have no idea but it's unrelated to RTAI.

LinuxCNC also needs to be built against the same RTAI modules and kernel packages as well otherwise you'll have problems either building or loading LinuxCNC's kernel modules as well. When you see "CANNOT FIND MAILBOX" please post `dmesg` so I can see what's going on.

edit: It is confirmed that there's a mismatch between the kernel image and the rtai-modules package. JT, you're not doing anything wrong from what I see, the debs are just bugged and need a rebuild against the kernel (rtai-modules and linuxcnc)

Andy, please use the latest checkout of my master branch. It has the GNU11 stuff and the musl math library is moved into kbuild as well.

Cheers!

I already pointed out in one of your other post about this very same topic that you were missing all spindle related hal entries and I suggested you create a new configuration with a spindle included. Have you actually done that?

Ich sehe nur den output vom startup der Konfiguration.
Interessant wäre zu sehen ob Fehlermeldungen ausgegeben werden wenn der ToolCone im preview verschwindet.

Sorry but i do not use RPI's at all,and that will not change untill their price drops back to under 50$.
 

They'll never be under $50 again. The world has changed, $50 is no longer $50.
