Hi, I've been trying out Orca's Adaptive Pressure Advance. Here: Adaptive Pressure Advance - OrcaSlicer Wiki, they write that the optimal PA is less the faster you print which fits my measurements, but, it's completely counter-intuitive. Can you explain why, when the head moves slower and the extruder has more time to gently react, it actually needs higher advance?
Hi, I'm using Ender 3 V3 KE, printing Soleyin Ultra PLA. I'm struggling with underextrusions at the beginning of lines. The starting few mm of line is consistently not sticking to the plate. At first, I though it's bed adhesion problem and z-offset, but the problem is not just the first layer but every layer. I think the retraction settings are to blame.
My retraction settings:
Length: 0.5mm
Extra length on restart: 0
Retraction speed: 30mm/s
Deretraction speed: 30mm/s
Z-hop settings:
On surfaces: all
Z-hop type: normal
Z-hop height: 0.2mm
I tweaked those settings a little and managed to fix missing beginning of lines, but now I have strings and blobs.
My first question: is the issue really caused by retraction settings?
Second question: how to properly calibrate retraction?
Thanks
