M566 P1 vs pressure advance

[AlexTh]

@phaedrux Re-extrusion during the printing of the filling at the "Line" in Cura. Underextrusion after retraction and transition to printing the next model on the table.

[Phaedrux]

Are you also using input shaping?

Can you post a photo of what you're seeing?

[AlexTh]

@phaedrux The printer is currently in operation. I'll take a photo tomorrow. I didn't understand how to insert photos here.

[AlexTh]

@phaedrux Input shaping is not used.

[AlexTh]

@phaedrux I understood how to insert photos. I didn't see on the phone that the chat functionality doesn't fit on the screen

M566 P1 vs M572 D0 S0

[AlexTh]

@alexth

M566 P1 vs M572 D0 S0.11 - Incorrect printing occurs at these values.
This is visible after moving to a new part.

@alexth is this behaviour different in RRF3.3?

[AlexTh]

@t3p3tony I am a new RRF user. I did not install other versions.

[T3P3Tony]

@alexth the board you had probably had an older version initially. Maybe @jay_s_uk can advise as this is a mellow board not a duet.

[PCR]

@alexth you have to tune PA with the specific jerk settings and policy.

[AlexTh]

@pcr I can't find the PA value, because the perimeter prints well, and only the beginning of the line with high underextrusion.

[PCR]

@alexth which printer? A PA value of 0,1 is quite high

[PCR]

@pcr for a direct drive

[AlexTh]

@PCR
Flying Bear 5
Long direct
~10 cm

@alexth start with S0 and increase?

[AlexTh]

@pcr I've tried different values. Can't set up.

But I'll try again

[AlexTh]

@pcr M572 D0 S0.07 is a more appropriate value, there is no underextrusion at the beginning of the line, but the outer corners of the model are slightly outward. For the perimeter, this value is not ideal.
