Hi All
Please can someone suggest next steps to try to get this to work.
I am a novice at this, so it must be something obvious, it’s just not obvious to me

Please see hal, ini, io attached.
I have a gantry X Y Y Z (two y motors)
I am using a Mesa 7i92TM connected from P1 to a Mesa 7i76U.
I have tried latest linuxcnc images on both Raspberry pi4 and on Intel NUC, and get the same outcome.
I used current version of mesact

The Linuxcnc dro counts on the screen, but the actual motors don’t move.
It looks like It counts in all axis until the software limits are reached, then errors.
When switched off, you can move gantry by hand in any direction.
When switched on, the gantry is rigid.
Stepper drivers are all DM556T.
Green led shows on all four of the stepper drivers (no red led on any of them)
I have wired from 7i76u to stepper drivers in differential mode, and in single ended mode with common ground, it made no difference, no axis moved.
The watchdog led in middle of Mesa 7i76U is green, and flashes approximately every second.
I have four inputs. Limit switches on the x and z axis, and proximity sensors on both ends of y axis.
In halshow, all four inputs are yellow, and go red if you trigger any of them.
Please can you suggest where to look next, or what config changes to try.
Many thanks

Hello
I put my pi 5 into operation yesterday.
Unfortunately I get the locale error with Pconf

I tried to use the same settings as you.
My keyboard is german

Do you have an idea?
 

I *think* you have to set the localle etc from menu-config - mine was not set for me.

If you're going to use a CM5 & carrier board you'd be crazy not to use an NVMe drive. It's fast, like really fast. I use one with mine Rpi5.

I have a LinuxCNC image running on a CM4/eMMC, so it should also work on the Pi5.

Hi, I got my latest image working. In /boot/broadcom under config.txt, you need to comment out the line that enables SPI: dtparam=spi=on -> #dtparam=spi=on.
Then you can use GPIO7 and GPIO8.

You do not need to load hal_pi_gpio, it doesn't work on PI5.

The good news is that you don't need it, either.

Uhi, das ist ja süß... all in one.

Ja viel können muss das nicht... Es handelt sich um eine Drehmaschine...
 

Willkommen im Forum,

die Aussage finde ich viel zu allgemein, es kommt auf die Drehmaschine an, wie diese ausgestattet ist.
Meine hat zB. nen Werkzeugrevolver mit Überwachung der Position, Glasmaßstäbe in X und Z,
programmierbarer Reitstock/Pinole, Spindelencoder, Bedienpanel, Minimalmengenschmierung.
Weiter geplant, Taster zum automatischen Vermessen der Werkzeuge.
Du siehst, da kommen eine Menge IOs zusammen, "nur" für eine Drehmaschine 

Hier gibt es sehr viele hilfsbereite und schlaue Menschen, man muss nur ordentlich Fragen.


Gruß
Olli

Ich habe aktuell dieses Interface:

www.sorotec.de/shop/Interface-Advanced-PRO.html

Mir geht es für das erste erst mal darum, mich mit diesem LinuxCNC zu befassen...

Ich hoffe es gibt hier sehr Hilfsbereite und schlaue Menschen in diesem Forum... ich selber kontruiere und baue Maschinen inkl. Elektrik aber bei Software ist es bei mir dann vorbei.

Moin,
willkommen im forum.

für den Raspberry gibt es auch einen Parport adapter, so könnte man ein altes alte Mach3 BOB vielleicht weiter nutzen:

byte2bot.com/products/parallel-port-raspberry-pi-hat

aber es kommt auch immer darauf an was man vor hat, es gibt da einiges an hardware die man nutzen kann: Mesa, Remora, Rio, GPIO.

Gruß Olli

Servus,

ich spiele schon länger mit dem Gedanken, auf LinuxCNC umzusteigen... jetzt habe ich gesehen, dass es das auch für den Pi4 gibt.... umsobesser

Die erste Frage ist nun aber, welche Steuerungsplatine sollte man hinter dem Raspi nutzen ? Aktuell habe ich Mach3... aber das mit der Echtzeit und alter gefällt mir nicht mehr!

Wer hat hier Tips für die Hardware zusammenstellug ? Handrad sollte auch noch her!

That would be lovely - the CM5 has one but then you need a carrier board and I don't know if the LinuxCNC image would run on the CM5/eMMC? With the right carrier board would be perfect though...

Dunn why RPi doesn't add a connector for an external antenna.

Just for completeness and to save anyone having to mess around with compiling kernel modules, here is what looks like a fairly comprehensive (at least until 6.13) list of in-kernel USB WiFi devices: github.com/morrownr/USB-WiFi/blob/main/h...in-kernel_drivers.md

Discovered it a little late but I think only one has an RP-SMA connection.

As the image is a custom one, only the kernel is built from RPi Sources.
This pretty clear, I would have thought.

To one well versed in building distributions, yes, but not necessarily to one who has only used distributions! Not until now, anyway

Where as you were attempting to install headers from the Debian repo

 
I was but at that point, didn't realise the significance of the kernel being sourced from a different place to the base distribution.

The kernel should load the drivers without any user intervention.

 
It does now load on boot.

Thank you.
