Thank you for your response PCW. I have checked and there is field power of 24v across pins 1&8 it is also tranfered to the nearby power block can't remember its tb number but done as mentioned in posts and manuals.
Thanks

The field I/O (TB4,5,6) is not GPIO.

If you assign TB5 or TB6 I/O pins or spindle (TB4) pins in pncconf and
you get pin not found errors, this most likely means that you do not
have field power applied (TB1 = ORANGE  connector)

So it’s actually possible. For some reason I thought MDI only accepts a single command and then blocks until it’s finished.
I’m working on my bachelor’s thesis about a 6-DOF robotic manipulator, and I’m planning to implement something higher-level than G-code. I assumed I’d first have to fully translate my logic into G-code and then execute it, but now I’m thinking of handling the logic in Python and sending commands directly to LinuxCNC instead.
Thanks for the help!

... very technical, but thanks anyway. I willl take a serious look at your post. By the way, yesterday I managed to eliminate the "noise" from the X servo. Now I just need to adjust the movement smoothly.

forgot to mention that in halshow i could not see any action on pins the only ones i could see were gpio pins and it listed 50 pins. Just for curiosity i looked at all 50 of the pins and tried activating the limit switchs and saw no change

Startiing on line 34 of hal limits not existing pin does not exist. I commented out all six lines after reltating to non existing pins to get thru with no errors. I checked these pins on TB6 04-09 and they all has voltage of 24v until activated then went to aprox .4v.There may be an issue with the board.
Thanks PCW

Hi thanks for the reply.
I found where it's printed but my question is what could cause the status buffer to be invalid after ~1hr of working flawlessly?
Is it possible it's some sort of hardware/memory corruption issue?

I was at exactly same point yesterday.
Everything runs perfectly until i add the spindle output.
I figured out that the spindle outputs are on the second half of the board which is internally connected by sserial. As I was testing everything on my desk, I just powered the board via the 5V supply. After digging deeper into the manual, I figured out that the field power needs to be applied as well. Some more LED lighted up, board was working

hope this helps

Hi, 
after running our system for a while, sometimes linuxcnc basically stops working, starts acting very weird and i get this in the logs
halui: updateStatus: status buffer is not valid
Can you please help me diagnose this, as I don't event know where to start looking.

No worries, I'm just not sure when that's gonna happen, Scott's not been active in the repo since beginning of January... Tried to reach out by email, no reply...

@grandixximo: I'd like to test it, but I'd rather wait until your changes and optimizations are incorporated into the official repository.
Until then, I'll stick with refClockSyncCycles="-1" for now.

ethernet - i've finished the hardware, but still working on software...

 

I have added 4th axis rotary and 5th axis tilting head, bascially XYZAB configuration. In vismach it moves machine parts (rotary and tilting head) as i move A/B axis. But tool remains at same loaction, it moves on xyz only.

Yes, test in sim for now, I have not run on a machine yet, but sim doesn't look too bad
