Another thing that comes to mind, do your servos have braking feature? The clunking and the resonance could be related to that if you do have brakes, possibly they are not being properly managed? I use braking on my Z servo drive, and if I lock it when idle I have resonance as well, that's the only thing that comes to mind, also it does make a noise when it engages more of a click than a clunk, just my brain went there...

Never had any of these issues, could be something with your configuration, ini Hal XML or the servo parametrization.
What my patch definitely improved is phasing, what could happen before the patch, was wrong phasing where latency could happen to sit on the threshold of when the servos were expecting the packets, and they could arrive at different cycles, making the motor grind, but all your listed issues probably have a different root cause. If you shared your configuration I could see if anything stands out to me. Other than settings it kind of sounds like an electromagnetic noise issue, are you using shielded cables for the ethercat network connections? Are all components properly grounded? Mostly the servo motors, and if you have a spindle with a VFD those need to be properly shielded filtered and grounded.

op state cycling. joint and limit errors when standing still, resonance. When the limit error happens it makes a clunk. It does not seem to ever have an issue in actual motion though.

You have no grinding noise correct?
Your problem is random OP cycling, and motor resonate when the machine is off or on?

Check on halscope and halshow, have lcec.0.dc-phased
app-phase
pll-error
pll-out

Those will show if the system is working proper.
See previous users posts.
 

dc phase is true
app phase is changing around 600k
pll error is randomly changing plus or minus 30k
pll out is minus 1000

Thank you all. Now that the old vcp is working again, I can try making the modifications I need to do.

I'll post back with either the final results or additional frustrations when I can work on it again Monday.

I take it back, all the same issues are there, zero change. Just took a while to show up.

So how do I check if it actually did the thing its supposed to do?

Could you share ini Hal and XML?

Bekommst du irgendwelche Fehler?
Vielleicht hilft es, wenn du das repo wechselst.
 

i think so. cant check now i but i think it was resonating when off the machine.
in omrons sysmac software (usb control) they are silent.

Hello
I know about the mesa cards and been eying them a lot and thinkng about getting one for my future CNClab BUT.
i found Ethercat and found that solution with connecting drivers ect with a simple ethernet cable and hat seems like a sturdy communication protocol.
the thing is i want to experiment with smaller motors and im fairly new to PLC components, most ethercat drivers and such are for larger and expensive motors.
does anyone know of a form of breakout board that i can use to send step/dir to for example a A4988 driver, i have a lot of old 3d printer hardware laying about. or could the add-ons for the EK1100 for digital output/input work for this? 
i'm just trying to get started with my lab so i can play around with different setups and learn linuxcnc thoroughly, a mesa card i probably in the future but atm my fixation is on ethercat.
 

Do you get resonance even with motors on bench?

ok, fixed. so the update works well. it does NOT solve the servo noise/resonance/howl. It does seem to have fixed everything else so far.

That one is pulling from several different sources, could you post the 404 error?
 

this is what i get, thanks
