After a longer than usual summer vacation break I've started another round of upgrades on the milling machine.

The first thing I did was to try and fix the leaks from my "Lincoln" clone progressive oil distribution block.

 

The tapered threads for the connections are not of the best quality and the built in check valves leak quite a bit.

This resulted in air in the lines if I didn't run the pump for the central lubrication for every week or so when the machine wasn't being used. It also left a pool of oil on the floor below the oil distribution block.

 

In order to try and fix this I removed all the connections from the block, cleaned the threads with brake cleaner and then reassembled it with Loctite thread sealant.

 

 

Then I added these small low pressure metal check valves I found on Aliexpress.

 

 

These changes seem to have significantly reduced the leakage from the oil distribution block and so far I have had no problems with air in the oil lines.

For GPIO it's in_not

INM is a better choice for inputs though  because it has built-in
debouncing if needed.

weird but this works
{HMOT](CARD0).inm.00.input-00-not

Thanks

I tried that and get the following error:

Pin 'hm2_7i96s.0.gpio.000.in-not' does not exist

Works okay without the -not

[HMOT](CARD0).gpio.000.in-not

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.

C axis is for rotation of the welding torch and this torch has offset between torch tip and rotation center of the C 

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.
