Ethercat random jitter fix

@ Atsu

I made a small change in my repo, get the new code, and make a new build then test, see if pll-err and pll-out get a value this time.

Thanks! Unfortunately I don’t have time to test this today, but will do it tomorrow at the earliest or Monday at the latest.

I will give it a shot. Thanks for the Feedback regarding my files 

So ive tried the new repo code and it still hasnt enabled dc-phase or shown any value for PLL-ERR or PLL-out except 0.

Im not sure if i plotted it correctly because i couldnt find the servo thread in halscope (is it servothread.time? ). However, please see attached image for pll-err and app-phase like requested.

Sync0Shfit was changed to 300000 aswell like you suggested

@TAKUYA
@Atsu

please check the value of the parameters lcec.0.pll-step
You can do so with this command

halcmd show param lcec.0.pll-step 

This parameter will be set at 1000 automatically if you have RTAPI_TASK_PLL_SUPPORT

also I have updated again the repo

if you could be so kind as to download, build and test again, thank you

I've never experienced any form of gravelly sound in my servos.

I do get the servos resonating under linuxcnc, when they are stable in the omron software. Is this the same core problem, or is it unrelated (a different bug)? The resonance goes away when moving above a few inches a minute.

My only other issue is sometimes there is a timing issue on start up where the drives will repeatedly cycle op states. happens on in 10 starts maybe.
