New and Working RTAI debs for 2.9

Category: Installing LinuxCNC

Sometimes it takes a few minutes for the panel and menu to load, I'm not sure why but I've noticed this with custom kernels on Debian.

As for the segfaults, I have an idea but it'd require new kernel debs..

qtplasmac "torch not showing"

Category: Plasmac

So neue Infos aber keine guten.
Hab’s jetzt mal auf meinem Gaming pc mit 13700k 3070ti probiert. Es ist immer das gleiche. Ich habe das Gefühl das ich irgendwas vergesse oder falsch mache.
Hat schon jemand die 2.9.2 direkt runtergeladen, auf usb kopiert, installiert und ausprobiert?

Haha jetzt kommst !!!!!!!

Ich habe bisher immer Advanced install option Graphical installer benutzt und da ist das problem bisher gewesen.
Jetzt habe ich einmal Live (amd64) benutzt und da funktionierts
So wie ich das gesehen habe wird da direkt vom usb gestartet.

Was macht den unterschied aus das es nicht funktioniert?

So weiterer EDIT

Ich habe es jetzt auf englisch installiert und hier geht die sim. Werde später noch alles richtig konfigurieren und dann weiter berichten

So weiter gehts!
Diesmal gute neuigkeiten es funktioniert. Habe ich die möglichkeit es auf deutsch zu ändern oder muss ich mit englisch leben?

UND VIELEN VIELEN HERZLICHEN DANK NOCHMAL FÜR EURE HILFE!!!

New and Working RTAI debs for 2.9

Category: Installing LinuxCNC

I left the PC running and when I came back I lost menu, mouse and LinuxCNC. I installed Debian 12 and used the Mate desktop if that makes any difference.

This is what Tom got.

Can I see the error messages Tom was running into or whatever the issue was? Any kind of trace or something?

Controlling mains 0-9v sherline lathe spindle mesa 7i96s

Category: Turning

The 7I96S analog output is a potentiometer replacement.
if you supply 9VDC to SPINDLE+ and SPINDLE- the output
will vary between 0 and +9VDC for PWM values of 0 to 100%.

It is expected that the potentiometer connections on the drive
supply this 9VDC.

Tom on the IRC had some issues running LinuxCNC until he isolcpus, I just installed Debian 12 then the debs and used grub customizer to add the isolcpu and everything seems to work well. Latency is insane low!

Linuxcnc xyz jitter when ide was created by danielb744

Linuxcnc xyz jitter when ide

Category: General LinuxCNC Questions

Hello everyone, I'm new to linuxcnc. I testing a new setup with stepper motors and mesa7i96s, it is working fine but at idle the xyz starts jittering even after homing the axis. This cause a vibration on the stepper motors. Obviously my stepper motors don't feedback the position to Mesa controller hence I don't understand why this is happening. Attach a 3 second video to show the issue 

Grateful if you could shed some light on this.

Controlling mains 0-9v sherline lathe spindle mesa 7i96s

Category: Turning

Hello,

    I am trying to control my sherline lathe spindle. It uses a potentiometer that is wired to mains. I have been looking at older threads for people who have done this but I am still a little unclear on the best approach. 

   It seems mesa 7i96s has a 5-20v isolated analog output - but I would need to convert thisto 0-9v to driver the sherline - what is the easiest way to go about this? I have read that people opted to use a firmware that gives the mesa an extra pwm on stepgen4 and do a pwm to analog conversion board such as spinx1A - but even with the spinx, how do you get its range of 5v - 21 to convert to linear 0-9v? Could you use something like a dc-dc buck converter (xl4015 or LM2596S)? Want to make sure I am doing things as safely as possible.
