  • RE: Pressure Advance seems to not be working.

    I haven't, no. I'm about to start printing things with PA of 0.5 to see how it is, ill bring my retraction back up a little bit to 3mm and see how I go from there. I will pick PA testing back up when I convert over to Direct Drive I think, I hate having bowden in the setup, I would much rather sacrifice some speed for quality.

    Its still bugging me seeing the extrusion just straight up fail with those PA values I were testing with, I feel like its just a single setting that is hurting my experiments but i'm unsure what it is.

    I really enjoyed my time using the Wilson 2's, but I'm so over the sketchup design and the way it performs its probing. I'm all for CoreXY now since joining in with Voron 2.

  • RE: Pressure Advance seems to not be working.

    I'm waiting for Voron Afterburner to get released out of Beta before switching back to direct drive (have two Wilson 2 printers with Direct Drive). This is simply to get me through to the point where I can print very nice prints until that point. But to be honest with you, I'm burning through filament and time at a crazy speed to get this single issue ironed out, I might just jump onto Voron's direct drive while its in BETA version.

  • RE: Pressure Advance seems to not be working.

    This was with 1mm retraction, will be dropping it lower tomorrow:

  • RE: Pressure Advance seems to not be working.

    A PA value of 0.7 is still giving me issues. How low should I realistically be looking to take the retraction down to when PA on? This was down to 3mm retraction at 50mm/s...

    The interesting thing is that the one line in the infil actually printed with the PA set to 0.9 but nothing else on those layers did...

  • RE: Pressure Advance seems to not be working.

    Thanks for that, much appreciated, makes a little more sense now.

    I have now kicked off a print with no coasting and 3mm retraction at 50mm/s and the following acceleration/jerk settings:

    M566 X700 Y700 Z60 E3000        ; Set maximum instantaneous speed changes (mm/min)
    M203 X18000 Y18000 Z3000 E15000 ; Set maximum speeds (mm/min)
    M201 X2000 Y2000 Z250 E3000     ; Set maximum accelerations (mm/s^2) 
    M204 P1500 T2000                ; Set printing acceleration and travel accelerations
    

    This print is testing the following PA values:

    Layers    | PA Value
    0 - 25    | 0.5
    25 - 50   | 0.0
    50 - 75   | 0.6
    75 - 100  | 0.0
    100 - 125 | 0.7
    125 - 150 | 0.0
    150 - 175 | 0.8
    175 - 200 | 0.0
    200 - 225 | 0.9

  • RE: Pressure Advance seems to not be working.

    I'm getting a little confused between M201 and M204, the duet gcode page is saying that M201 is per axis acceleration and M204 is for printing overall, will only the lowest value get used when it comes to printing?

    @Phaedrux - Combing has now been disabled, i'm joining the dark side!

  • RE: Pressure Advance seems to not be working.

    @burtoogle - I do have combing enabled, but its set to 10. Your branch of Cura freezes up when its idle for about an hour or so, I have to keep reopening it up when I get back to testing a new set of slicer dependant settings. Not a problem, just thought I would let you know 🙂

    @Phaedrux - I have changed my retraction to 3mm at 40mm/s. I will increase the extruder acceleration now as you suggest. Would you go lower than 3mm, I can test this out myself but while I print a test with these new settings just thought I would ask.

  • RE: Pressure Advance seems to not be working.

    Print has just completed with the following settings

    Speed Settings:

    3f4483ce-718b-4e67-b837-e9a5c61079ec-image.png

    M566 X700 Y700 Z60 E2000        ; Set maximum instantaneous speed changes (mm/min)
    M203 X18000 Y18000 Z3000 E15000 ; Set maximum speeds (mm/min)
    M201 X2000 Y2000 Z250 E1800     ; Set maximum accelerations (mm/s^2) 
    M204 P1500 T2000                ; Set printing acceleration and travel accelerations
    

    Current Settings:

    ; Drive currents
    M98 P"/macros/print_scripts/xy_current_high.g"	; XY (AB) currents high
    M98 P"/macros/print_scripts/z_current_high.g"   ; Z currents high
    M906 E1600                                      ; E current
    M906 I30                                        ; idle current percentage
    

    PA Values:

    Layers    | PA Value
    0 - 25    | 0.3
    25 - 50   | 0.0
    50 - 75   | 0.4
    75 - 100  | 0.0
    100 - 125 | 0.5
    125 - 150 | 0.0
    150 - 175 | 0.6
    175 - 200 | 0.0
    200 - 225 | 0.7
    

    Results:

    IMG_8794.JPG
    IMG_8796.JPG

    Conclusion:
    If PA is now functioning correctly, I have something else to be dealing with, more than likely retraction prime amount. I'm not really convinced by any of the PA values here but if I had to choose one, I would have to say 0.5 performed the best. I was hoping the severity of my seam was due to PA, but it seems (no pun intended) that its not helped me at all really. I imagine it will serve a huge part in correct infil lay down though, you can see on the rear of the print (side with no seam) that on the PA=0 layers you are unable to see where the infil joins the walls, so thats a huge positive from this exercise.

    Time to start troubleshooting other settings to help me with hiding the seam, most prints will have their seam on a corner, but sometimes the seam is out and visible (round objects) and I would like to dial that in if possible.
