Well, that was easy! Thank you sirl
I think I'll make some chips!

Set the servo period in the ini file to 2000000 (2 million) and set the P value for each joint/axis to 500.

So... 

What if LinuxCNC complains while starting...?

When running the latency test Tommy suggested, I saw a similar graph.

I migrated my working configuration to the PI4.. Then, I was visited by the dreaded latency complaint. 

Everything appears to work. I am running a Mesa ethernet card. What are the steps to debug and rectify the situation on a PI? 

Frank.hal attached. Do you need to see any more files?


 

Hey,
i'm running LinuxCNC 2.9.4 on a Raspberry Pi 5 in combination with a Mesa Card 7i96S.

I seem to be doing something wrong with my limit switches.
When i manually trigger one Switch all LED's to the coresponding pins to the 4 Limit switches on the board turn on.
They are wired to the board as seen in the picture following
X = 0 / Y1 = 1 / Y2 = 2 / Z = 3
The VCC and Ground are wired in parallel to the 5V and Ground the Mesa card is connected to.

Any help would be appreciated. 

@rodw excellent ! I couldn't spot any differences from x64 build

Parport bob is easy to use.
There are guides to set it up.

It isn't supported out of the box but you could build it from source. I made a video

 

linuxcnc.org/docs/html/install/latency-test.html

ok and the stripes on the sides are indicator for bad latency and the middle doesnt interrest?!

When not using --show , the stripes on both sides of the graph will show that there are latency excursions beyond the visible area, meaning the latency is so big it can not be shown on the graph.
Using --show will add two more fields where the number of excursions is shown.
In short:
-stripes on both sides = bad latency that can not be shown in the graph
-no stripes = latency is only as shown in the graph.

aaaah ok... i dont undeestand because i see in the middle the big Mountain.. but left and right only 2 small stripes...

i trust what you say but dont understand in all.

Is it possible to use the Master version on a Pi5 ?

Ok I see it's a windows EXE, correct ?

What Mesa boards does it cover ?
What issue were you having with the supplied tools with Linuxcnc ?

Latency excursions beyond the visible graph area.

and what does this mean? thanks
