Hello,

For me, he basically does the first (rough measurement) until the step comes back, this is no longer carried out, regardless of whether the workpiece height or tool length and the whole sporadically.
It happens that I finish several parts with the same program and the first or two run through and then it caught or just caught.
If you wait, a timeout comes as described.
At the moment I only come out when I end Linuxcnc, I haven't tried something else yet.
I suspect something swallows in the order.
I have already discharged the trial entrance, but that was also unsuccessful.
I'll try to implement this with the spindle and see what happens.

Until then, greetings to everyone, Frank

That does seem inconsistent, but at the same time you almost always _don't_ want the spindle to spin with the probe loaded. Especially if it's a wired probe.

Which of these do you want to use? They aren't really compatible. 

You could use the spindle-override controls indirectly, using a HAL "scale" component to multiply the motion.analog-out.NN pin by halui.spindle.N.override.value
linuxcnc.org/docs/stable/html/man/man9/scale.9.html
linuxcnc.org/docs/stable/html/man/man1/h...l#Spindle%20Override

The xml file from stepperonline is for something else.
You need a xml file that maps the linuxcnc internal "pins" to the drives PDOs.
There are numerous examples if you search for "A6 ethercat-conf.xml" in this forum. You can start with one of these and then adapt to your needs.

check with command "ethercat slaves". Errors show up in syslog.

You can set SDOs permanently with "ethercat download".
There can be a maximum of 10 PDOs in the xml file.

You may be seeing a problem caused by the G-code preview. That runs through the code to draw the lines, but won't update values based on probe results etc (as it doesn't _move_ anything).

The trick here is probably
Which will end the loop early in preview generation.

Since it's not realtime, you should be able to make a simple (python?) userspace
hal component using the kernels serial driver.

The idea is that the images make the parameters self-explanatory.

All of the macros start from the current position of the tool.

So to machine a radius on the end of a bar you would set the diameter of the bar in the diameter box, the Z of the end of the bar in the Z box, enter the required radius.
Make sure the correct radius position radio button is selected.

For an external radius on the right-hand end of the work you then jog the tool tip to somewhere just outside the material diameter, and just to the right of the material end, and press the button.

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?

SPINDLE+ (TB2 pin 24) on the 7I96S must connect to the VFDs 10V

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.
