It will work fine, so change it.
While you are getting the error, that causes lost steps, usually not noticeable if the latency is not bad, very noticeable if latency is really bad.

Ok value changed to 100000.
I can't check the result, milling machine is not built yet :( .
Wait and see...

This affect the max speed.
For this time go back to 50000.

You will have to test it out but speed with lost steps is worse than slow rapid speed

Today I run latency test for a from 8 o'clock to 16 o'clock, watching milling videos on YouTube :silly:, reading LinuxCNC documention...
I finally obtain 69358ns max jitter.

I download StepTimingCalculator.ods file and get this result :


In INI file setup this values :
Code:
BASE_PERIOD = 70860 *_VELOCITY = 44.10

In HAL file setup this values according to Calculator file :
Code:
setp stepgen.x.steplen 1 setp stepgen.x.stepspace 1 setp stepgen.x.dirhold 2 setp stepgen.x.dirsetup 2


I get the same latency message when I run LinuxCNC.

What's wrong ?
