Duet 2 Wifi - First Time playing with Pressure Advance

xenon2008

Hello together!

I am currently "playing" for the first time with Pressurce advance, and must take care that this function protects the pressure-protected "strong" rectangle!
Now I have read man should pay the jerk for the extruder, I have also heard these belong from 5mm / sec to 10mm / sec!

But since I am still completely new to the subject, I wanted to ask for your help, whether you could give me tips on how best to set up or configure Pressure Advance.

I have currently determined a K-factor of 1.3 and stored this in Prusaslicer via the filament G-Code!
The corners are now a lot nicer.

I'm just wondering if my value of 10mm / sec jerk at the extruder isn't too much?
And whether my other values like acceleration and so on are correct?

config.g:


; Drives
M569 P0 S1                                     ; physical drive 0 goes forwards
M569 P1 S0                                     ; physical drive 1 goes backwards
M569 P2 S1                                     ; physical drive 2 goes forwards
M569 P3 S0                                     ; physical drive 3 goes backwards
M584 X0 Y1 Z2 E3                               ; set drive mapping
M350 X16 Y16 Z16 E16 I1                        ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z1600.00 E415.00             ; set steps per mm
;M566 X720.00 Y720.00 Z120.00 E300.00           ; set maximum instantaneous speed changes (mm/min)
M205 X8 Y8 Z5 E10                               ; Set max instantaneous speed change in mm/sec jerk
M203 X12000.00 Y12000.00 Z300.00 E6000.00      ; set maximum speeds (mm/min)
M201 X2000.00 Y2000.00 Z120.00 E1500.00        ; set accelerations (mm/s^2)
M906 X1250 Y1250 Z1000 E1000 I30               ; set motor currents (mA) and motor idle factor in per cent
M84 S180

Hope everybody can understand what i mean, because my English Skills are not very good.

If your Linear Advance K value is 1.3 for RRF it should look like this:

M572 D0 S1.3

Your jerk and acceleration values look fine to me.

this is exact this what i have entered in my Filament Start Gcode in Prusa Slicer.
So 10mm/s Jerk is not too much?

Got my extruder even at a higher jerk value.
If you don't hear any clicking it won't be a problem.
