Thanks for the help. Sending this because I'm not sure I posted my next question in the right way..

Hallo Juergen,

danke für den Screenshot. Ein paar Fragen, damit ich das nachstellen kann:

1. Welche Distribution und Version läuft (z. B. Debian 12 vom LinuxCNC-Image)? Live-USB ohne Installation oder installiert?
2. Welchen Eintrag im Menü Hilfe haben Sie angeklickt: Benutzerhandbuch, Nach Updates suchen, Diagnoseprotokolle exportieren oder Über Takshak?
3. Wie lautet die Fehlermeldung genau? Die beiden Meldungen rechts oben im Screenshot ("Install Failed" und "Not running on one of the supported Live systems") stammen nicht von Takshak.
4. Wie wurde Takshak gestartet, AppImage per Doppelklick oder im Terminal? Am hilfreichsten: im Terminal starten mit ./Takshak-1.0.5-x86_64.AppImage, dann Hilfe anklicken und die Terminalausgabe hier einfügen.
5. Falls es noch geht: Hilfe → Diagnoseprotokolle exportieren, und die ZIP an die Support-Adresse senden.

Für künftige Fragen und Meldungen gibt es übrigens unsere eigene Community unter hub.takshakcam.com. Dort sehen wir alles sofort, und wir möchten das LinuxCNC-Forum nicht mit Takshak-Themen belegen.

Viele Grüße
Georg

Thanks for the help, making much progress. New question:
What is the syntax to negate these inputs?

# external input signals

# --- MIN-X ---
net min-x     <=  [HMOT](CARD0).gpio.000.in

# --- MIN-Y ---
net min-y     <=  [HMOT](CARD0).gpio.001.in

# --- MIN-Z ---
net min-z     <=  [HMOT](CARD0).gpio.002.in

# ---setup home / limit switch signals---

net x-home-sw     =>  joint.0.home-sw-in
net min-x     =>  joint.0.neg-lim-sw-in
net x-pos-limit     =>  joint.0.pos-lim-sw-in
 

My crystal ball has stopped working....
More info, pictures, configs...

Hi all;

My question is simple. No changes have been made to wiring or configuration, yet Y2 stopped working. I verified connectivity between the motor and the breakout board, all is good. I next tried swapping the plug position between my A axis and the Y2 axis, modified the hal file to reflect the swap and restarted LCNC. Now the X axis has joined the problem. Z still responds correctly.
What is more likely, a failure of my MESA 7i76U driver board or the breakout board or both?

Kind Regards,

Yes, exactly.

Yes it is the C axis. It's just that the A, B axes in the image are not in the referenced orientation.

This is not the C-axis.

I see. Yes, that would require a new kinematic model. Basically the 'xyzab-tdr' expanded with the tool side c rotation and the torch tip offset.

Hi,

i attached representive photo of the machine. 

C axis is for rotation of the welding torch and this torch has offset between torch tip and rotation center of the C axis This ofsett can modified by operator according to welding jig.

A and B axis are for rotation of the object that operator needs to weld.  

I'm afraid I don't have a ready made kinematic for a machine with 2 work side rotaries and one spindle rotary.

Do you have a picture of the machine geometry? I'm having trouble picturing a spindle with a C rotation only. C would rotate around the Z axis and usually the spindle itself is aligned with the Z axis.

Hi Aciera;

First of all, thanks for your great work.

with config "xyzbca-trsrn" it is very easy to make nutation-angle = 90 if machine doesn't have nutating head and it works properly with 90 degree nutation agle.

what about if A axis is on the plane like B axis, and only C axis is on spindle ? is there any easy way to do it with config  "xyzbca-trsrn" ?

i checked "xyzab-tdr" config too but this config doesnt have C axis on spindle. and also i checked "xybc-trt" .

what is the correct way for  configuration xyzbac- table rotay- table rotary  - spindle rotary ?   

 

6 SmartSerial interfaces with ZYNQ 7010 and SPI Ethernet , on first one ethernet port Ethercat is configured

I ordered new switches and replaced them and now the homing sequence is working and latching fully. Now homing works all the time with no errors and I did not change any settings in the configuration.
 
The old switches are at least two years old so it could have been contact bounce. Big thank you to everyone for your resourceful feedback and kind help.
