So I am having issues making M593 effective. No matter what F I use, I don't see anything changing.
I bumbed up my vel, my acc and lowered jerk.
From --> to
Vel = 45 to120
acc = 500 to 2000
jerk = 900 to 300
from there my result got instand better even without appling M593. So my ghosting is defenatly depending of frequency. I calculated M593 and depending on my acc (even used 8000 on acc) i got results from M593 F64 till F154.
I ran test where I changed F every mm from 30 to 180. Nothing changed. I did a lot of testing, runing different acc to jerk to frequence matrixes. NOTHING
I figured something only very late and I will have to do some test, but I guess I realized what my issue is.
I am using a high pressure advance value of 1.2. Which gives me charming results.
Therefore I also raised my jerk on E to compensate my high S1.2. So I went from 250 up to 500.
but that seems to little. I think the PA is reducing the Jerk of E so much, that it will influent my motion totally and even impact M593.
My last result I did I ran different setups in changing my motion parameters. After running Vel 120 and acc from 2000-3000 I decided only on the last mm on top to turn of PA and see, no ghosting. not a little. Of course crapy edges but no ghosting.
So I tried with higher jerk for E in PA = 1000. that got me close to the edge of my extruder unit not tu junk or eat the filamet.
So I wonder if there is a way, for me using PA and DAA. righ now I can't see it and I think that might be the issue why most user won't see an effect on DAA. At least with bowden setups as I have.
I assume, to calculattion of the motion profile to avoid certain frequency, is using the jerk and acc values set for x and y. But the actual movement is dictated by the Extruder depending in the PA setting.
Only my assumption.
And just for real lovers, I am running an Omerod2 modified to a monster. (Duet2Wifi and latest firmware to this date)
