Strange Blobbing on Layer Change
-
Does prusa slicer now allow per move jerk settings as well as acceleration? I didn't think so.
The PrusaSlicer has its own jerk setting (mm/s), maximum acceleration (mm/s²) and maximum feed (mm/s)
for each axis. -

Where? You mean in the machine limits?
-
@Phaedrux
Yes, exactly.
But it is clear that the upper limit is determined by the config.g. -
-
Yes, I made those changes in PrusaSlicer.
Are you suggesting that I make the changes in config.g?
And if so, is that command M566?My current M566 is not labeled "jerk" so I just want to confirm.
M566 X1500.00 Y1500.00 Z600.00 E120.00 ; set maximum instantaneous speed changes (mm/min) M203 X12000.00 Y12000.00 Z600.00 E2100.00 ; set maximum speeds (mm/min) M201 X1500.00 Y1500.00 Z500.00 E250.00 ; set accelerations (mm/s^2)
-
Yes, maximum instantaneous speed changes is often called jerk.
-
Got it. Do you have some recommendations from my current settings?
-
@davidewen Try these
M566 X1500.00 Y1500.00 Z600.00 E3000 ; set maximum instantaneous speed changes (mm/min) M203 X12000.00 Y12000.00 Z600.00 E6000 ; set maximum speeds (mm/min) M201 X1500.00 Y1500.00 Z500.00 E3000 ; set accelerations (mm/s^2)

@Phaedrux
Thanks for the info. This has helped a lot. Seam is still there, but greatly improved.
I will play around with these settings to see if I can get it to almost perfect.Cheers!

Have you tune pressure advance yet? That's the remaining piece of the puzzle.
