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.

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.

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

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...

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

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!

@burtoogle - Windows 10 on 8GB RAM, i5-3570K @3.4GHz (stock, not OC'ed) with a AMD Vega 56. If you need any specific information, please feel free to contact me privately to avoid clogging this thread up, more than willing to chat.

@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.

Print has just completed with the following settings

Speed Settings:

M566 X700 Y700 Z60 E2000        ; Set maximum instantaneous speed changes (mm/min)

M201 X2000 Y2000 Z250 E1800     ; Set maximum accelerations (mm/s^2) 
M204 P1500 T2000                ; Set printing acceleration and travel accelerations

Current Settings:

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.

I have indeed seen that, I'm currently printing another with 5% infil with two walls. Its like I knew what you was going to say haha. My extruder is now behaving a little more like expected, sounds like a machine gun now, but like its skipping steps, I'm running M122's to check for missed steps but seeing nothing. I have brought my Jerk down to 3000 for this test just to stop the extruder exploding while i'm testing for the right PA value, at 3000 it still sounds like its going to explode now.

I still have the outer wall set to 17mm/s, I might need to change it to configure PA though, so might need another print after this before I see any difference in the print.

Neither of them are enabled and my speed is what I would class as fairly slow if i'm honest with you.. 17mm/s (i'm only printing a single wall)

This cube has come out with no visual difference up the seam again. I had the following PA values at the respected layers:

Layer   | PA Value
25      | 0.7
50      | 0
75      | 0.9
100     | 0
125     | 1.1
150     | 0
175     | 1.3
200     | 0
225     | 1.5

No change at all other than it stopped extruding a little for 6/7 layers during the 1.1 value set of layers (layers 125 to 150).

How far before the seam point on each layer should PA start to kick in because its literally right on top of the seam that the extruder shows some movement for PA. It doesn't change at all for the corners, its one continuous extrusion from start of layer to the end of the layer. I'm not sure it should really be like that....

@DIY-O-Sphere - Retraction is 4mm at 60mm/s with a prime at 30mm/s and with Rigid Ink ABS in Black.

Edit: Correcting a typo

Printing now with a Jerk of 5000 to give the extruder some chance of not being the fault of the next print (I will see if I hear any skipped steps), PA ranging from 0.8 to 1.5 with 0 between every 25 layers. Will post back shortly when its all finished.

@Phaedrux I did mean 0.5-0.7 sorry. I'm currently getting the printer ready for the print I said I'm running so I will change some settings back now then. I will put the Jerk back to the original 8000 (this is the default for this extruder, the majority of the community are running this value, with PA), and will change my test to range from 0.8 to 1.5 to see if I see any changes there.

How does that sound, too much or still too little PA?

I still believe there is something causing PA to not take full effect, i don't believe there is much change on this new cube either. I've lowered my Jerk even more but the fact that I don't see much change at all up the seam, I don't believe its having full effect. Testing another cube now with a Jerk of 400.

Currently trying the print again with Jerk set to 800 rather than 1000

@DIY-O-Sphere - This is a 4:1 ratio extruder

@zapta - That is such an awesome addition to the slicer!

@DIY-O-Sphere - So something like the following:

0-5mm: PA 0
5-10mm: PA 0.2
10-15mm: PA 0.4
15-20mm: PA 0
20-25mm: PA 0.6
25-30mm: PA 0
30-35mm: PA 0.8
35-40mm: PA 0
40-45mm: PA 1

I have been doing it just one after another without a 0 between, I see what you mean now, it will enable me to check all the way through the range easily back to original. Thank you, will get that done now.
