Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

Category: Installing LinuxCNC

Wifi setup is by running
sudo menu-config

Be sure to edit to choose option 5 "Edit wpa_supplicant" with your country code, ssid & password.

To setup network for a mesa fpga Ethernet card, choose option 6 "Edit interface" and modify eth0 to match post above if you have jumpered the board for "FIXED FROM EEPROM"
If you have jumpered for "FIXED 192.168.1.121" replace 10.10.10.100 with 192.168.1.100.

If your home wifi network is on the 192.168.1 network, use the 10.10.10 network for your Mesa card, refer to you card's manual for jumpers to change.

After config reboot
To check the network type in a terminal
ip a

Taken from 7i92 Manual
IP ADDRESS SELECTION
The 7I92 has three options for selecting its IP address. These options are selected
by Jumpers W5 and W6.
W5   W6    IP ADDRESS
DOWN DOWN  FIXED 192.168.1.121 (DEFAULT)
DOWN UP    FIXED FROM EEPROM
UP   DOWN  BOOTP
UP   UP    INVALID
Note: that the initial EEPROM IP address is set to 10.10.10.10 at Mesa, but can be
changed to any address with the mesaflash utility.

A final note, there is no network notification applet for the desktop, so you will not get any notifications when the network connects, disconnects or reconnects.

Dahlander spindel motor starter with direction

Category: General LinuxCNC Questions

Hi all
I have made this diagram, but is there a smarter way to control this motor ?
I have all the parts on the shelf, but i think its a lot of relays just for a small 5kW spindel.  
The motor is a 2 speed Dahlander motor. Running 400V 3 phase 50 Hz.
I have not drawed fuses and thermal relays on the diagram yet but know where to place them.

Guten Abend Peter,

leider konnte ich keinen weiteren Fehler provozieren. Die Maschine lief für drei Stunden ohne Fehler?
Trotzdem habe ich jetzt die neue Festplatte eingebaut und eine komplette Neuinstallation von Linux CNC durchgeführt.

Gibt es eine Anleitung zur Einrichtung die du empfehlen kannst? Es gibt "leider" sehr viele Informationen zur Einrichtung und jede ist ein bisschen anders. Irgendwo habe ich auch gelesen es kann Probleme geben wenn man grafische Oberflächen und textbasierte Einrichtung mischt. Ist das richtig

Orientiert habe ich mich an dieser Anleitung
docs.google.com/document/d/1jeV_4VKzVmOI...ading=h.macj649sy0yq

Darin wird auf diesen Eintrag verwiesen
forum.linuxcnc.org/38-general-linuxcnc-q...-irq-affinity#292969

Der wiederum etwas anders vorgeht.
Vielleicht habe ich bei meiner ersten Installation/ Einrichtung zu viele Parameter bearbeitet und es gab deshalb die Probleme...


Grüße und einen schönen Abend

The recommendation is not related to your problem, which is here:
HAL: ERROR: function 'pid.s.do-pid-calcs' not found
./Editlindowxzc3-11-25rev2.hal:21: addf failed

So please attach your hal and ini files.

Where do I add the suggested script fix in my configuration?  The converted file from my XZC coordinate system does not work.

Report is attached.  Can provide HAL and INI if needed.

Thanks

the origin switch is probably what your after, but you might want to make sure it consistently repeats to within a few encoder counts every time or it's useless for things like threading etc.

You should never get a runaway, but you will get oscillations with a too high PID value

To avoid a runaway around 0 speed where a negative PID output may occur might require
some hal magic, say using the PID output sign to run the VFD direction signal or forcing the
PWM value to 0 when the PID output is negative.

"uspace" in this context means using a Preempt-RT kernel.
(rather than RTAI or some other real time kernel)

Thanks. Yeah I think the main problem was that I have set the P value too high (above 2 is too much --> runaway). So the system seems to be working now.
  • I set a non-zero value to the DEADBAND setting (10)
  • I am using a low pass filter on the encoder feedback signal before feeding it to the PID loop
  • I use a low P value to stop the system "from running away"

Normally this is just done with normal PID,
with FF0 set to 1 and PWM scale set to RPM at 10V

PID would mainly be for Keeping constant RPM vs load.
If you have major non-linearities, these can be corrected with
the lincurve component.
