Have you found linuxcnc.org/docs/stable/html/hal/basic-hal.html ?

Did you want the laser PWM controlled by both the feed rate and motion.analog-out-00?

If so you probably want to add a scale component to multiply the analog out setting by the feed rate.

pncconf (at least in 2.9.4) does seem to do the right thing.

SSR 00 for Spindle CW and SSR 01 for Spindle CCW:
( they are in odd locations on the screen)


  


This does generate the expected connections in the hal file:


 
 

Andypugh, Thanks for reply!

I didn't use mesa board. I think about ehtercat + rs232 , this is more simple for me (ethercat modules avaible from stock, but mesa is not available). But of course best way to use onboard rs232 to sending and receiving data.

About realtime -This is not critical , because speed is 19200, so i dont need realtime.

I will read links more detailed this evening.
And may be there are some another way if no needed realtime.

Does your system have a Mesa card? If it does then you could look at using a Mesa UART.

Otherwise it ought to be possible to use the onboard serial port, but for some reason I haven't seen anyone do that through HAL in realtime.

In theory you ought to be able to do it with inb and outb commands:
stackoverflow.com/questions/47048726/bau...-outb-commands-linux
(note that the advice there is "don't" but they are not considering realtime limitations)

There is an existing hal component that uses the serial port status lines for GPIO
github.com/LinuxCNC/linuxcnc/blob/master...drivers/serport.comp
which it might be possible to tweak. But the fact that nobody seems to makes me wonder if it is impossible for some reason?

die zwei Befehle bewirken kein 'Systemupdate auf Version 13'.
'sudo apt update' bringt nur die source list auf den neusten Stand. Es wird keine Software runtergeladen und nichts installiert.

'sudo apt install freecad' lädt Freecad (gemäss Source list) runter und installiert es.
 

Ja, das stimmt. Ich habe es gerade eben ausprobiert, es hat die Version 0.20.2 installiert. Ich muss zuvor irgendetwas Anderes gemacht haben, was zum volständigen Update geführt hat. Bei ihm sind aber trotzdem zumindest Terminal, Dateimanager und Browser weg.

Wie auch immer - wenn man das richtige Image heruntergeladen hat, läuft die aktuelle Version 1.0.2 ohne Installation. Heruntergeladen habe ich es hier:  www.freecad.org/downloads.php?lang=de
Vielleicht ist es auch bei ihm so. 

Thanks. I'll have a look at it.

Habe das Problem gerade gelöst. Auf der Downloadseite von FreeCAD gibt es 2 Linuximages: x86_64 und aarch64. Da LinuxCNC bei mir auf einem Raspberry läuft, funktioniert nur Letzteres. Aber es funktioniert 

Die heruntergeladene Datei kann man ohne Installation ausführen, wie in der Anleitung oben beschrieben: 

After download, right click on it, properties, permissions, check "Allow executing file as program", close, double click on it.

vermutlich weil du schon mit:

sudo apt update
sudo apt install freecad

ein Systemupdate auf Version 13 gemacht hast.

Hallo,
hast du vorher eine Sicherung gemacht? Bei dir sind die Programmverknüpfungen in der Taskleiste nicht mehr gültig, vermutlich weil du schon mit:

sudo apt update
sudo apt install freecad

ein Systemupdate auf Version 13 gemacht hast.

Sind deine CNC-Programme noch da?

Ich jedenfalls versuche seit 2 Tagen bluetooth, flatpak etc. zu installieren, was immer wieder zum Update auf Version 13 geführt hat. Ich nehme an, sobald man etwas installieren möchte, was eine höhere Linuxversion erfordert, wird automatisch ein vollständiges Systemupdate durchgeführt.

Hi.
i need to read every 100 millisec some values from rs232. (Old equipment and i haven't source) and during work have to change this values. Also with this values i switch to working state equipment. I understand command which i have to send and to read.

And now i see only solution when i write all commands on the arduino-like board for connecting with target board, and for upper lever (linuxcnc) via mobdus (arduino as slave). But im trying to find more simple solution with only linuxcnc.

how to do this elegance)?

Regards
 

As an alternative have a look at
'sim/axis/vismach/5axis/table-rotary_spindle-rotary-nutating/xyzbca-trsrn_twp/xyzbca-trsrn.ini' which uses 'xyzbca_trsrn.comp'

Set 'xyzbca_trsrn_kins.nut-angle' to 90°

Hi, I am creating a custom machine for work and really really need help. I am using the above driver with a 1000w servo motor for the spindle. I have installed ethercat and configured. I have downloaded the xml file for the drive from stepperonline. I have created a hal file that loads lcec and the xml file. But when I start linuxcnc is stops with an error saying lcec exited. How can I use this to drive the spindle. I don't need limits or probes or anything, Just speed.

I am really out of my depth here as I normally use a 3ph and vfd but space and weight does not permit this on the machine I am making.

Thanks

Sort of. It looks like Spindle-at-speed needs to be true for motion commands to executed. And since there are G1 commands in the probe routine, and the inconsistency in hy_vfd mentioned in my previous post, execution was halted in probe latch return (G1 move) and the timeout error occurs.

To be clear, I do not see any fault or bug in the probing routine. And I think the way linuxcnc is handling spindle-at-speed signal is correct for motion.

The docs of hy_vfd sais:
But the source code for hy_vfd mentions that the spindle also needs to be turned on for this signal to work
github.com/LinuxCNC/linuxcnc/blob/27706f...ng-vfd/hy_vfd.c#L123 

As I hade net hy_vfd.spindle-at-speed to spindle.0.at-speed, after a spindle start and stop, this signal never got TRUE when the spindle stopped, and all subsequent movements where halted. 

Interestingly, G38 moves is not dependent of spindle-at-speed signal, do not know if this is intentional or a bug in linuxcnc code.
