After Month of machining without any problems -Positionerror and no more moving

Hi at all,

Yesterday, after many Month of working without any problem, my Mill stops with an error "Positionerror ...".
My config runs on Probe Basic with a MESA 7i96S and a7i85S (for the aditional linear-encoders)

I restartet Probe Basic, but every time I tried to reference, i allways got the same error and not just one axle moves.
Also I checked the voltages and all seems OK.
To find out if there ist just a basic funktion, i startet a new config with the wizard. 
After setting up the MESA 7i96s (IP 10.10.10.10), opend up the test-movement-mask, activating the axle, i tried to move the axle, but nothing. (The HAL-Scope shows a feedrate like it should do)
I Tried this for X, Y and Z but nothing!

So at this moment I`m wondering if there is a problem with the MESA Card.
Is there someone who had a similar issue and could give me a tip.
By the way, if I move the axles by hand, all the linear-Encoders at the 7i96S works fine.

Thanks a lot.

Hi andy,

there is no movement at all.
At the wizard i testet every axle (X, Y, Z) and not just one moved.
At the HAL-Scope i could see the feedrates on every axle, but no movement. 

Every tim I try to do the reference, i get this error
In the Terminal is the following:

I tried to copy the whole starting-log out of the Terminal, but i can`t becouse i got the error-message "there are too many links in this post...." 

So i attached an file.
 

Also here the readhmid from the MESA 7i96s
 

Short Update.
Fortunately, I had a second MESA 7I96s here. I flashed it to the right firmware and installed it.
After that, it seems that everything works fine now.

Will replug the old one just to check if there was no connection-problem.
I will give a feedback how it will go.

 

Sounds like a hardware or wiring issue with the drives or 7I96S step/dir outputs, as there is no motion
and no obvious errors.

Is there a common enable for the drives?

Can you increase the following error limits and try jogging in each direction to see if the DIR outputs
are  at valid voltage levels and change direction on reversals?



 

OK, looks, like the old MESA Card has an issue.
I reconnected the old one and same problem.
Now I installed the second one and everything works fine.

So it's a new experience that MESA cards can also break down sometimes. 

Thanks a lot to all.
Next project ist coming with upgrade to an ATC Spindle with a Cabinet.

best regards.

OK sounds nice.
I also didn`t think that this cards realy break.
So i will test this card on my new mill if it`s ready and hope it will work in a new envirement.

Thanks Tommy
