Gaps between different colors | 3D Printing | Page 1

I'm using P1S with AMS, trying to print something thin (bookmark) with 3~4 colors. Usually those gaps are where the seams are, but sometimes it also happens on the walls of one color.
I tried to reduce the amount of colors I use, but the issue still exists.

What should I tweak? Flow rate of certain colors (in this case it seems like black is the culprit)? Retraction length? Smaller seam gap?

I feel like it's the shrinkage of certain colors...

AI Help

To address gaps or inconsistencies in your multi-color prints, there are a few things you can try:

Adjust your retraction settings: Experiment with increasing or decreasing the retraction length to minimize stringing and material oozing between color changes.
Check your temperature settings: Ensure that your filament is being extruded at the correct temperature for each color, as different pigments can require slightly different temperatures.
Verify your filament diameter consistency: Inconsistent filament diameter can affect the flow rate of each color, resulting in gaps or under/over extrusion.
Optimize your seam placement: Try adjusting the seam position to a less noticeable area on your print, which may help mitigate any issues caused by color changes.
Consider printing a small purge tower: Printing a small purge tower next to your main print can help ensure smooth color transitions and help remove any residue from the nozzle before switching colors.

In term...

@magic flower Also maybe look into linear \ pressure advance (pattern method)

I tried PA tower, but it's quite hard to see or feel which layer is the true right angle 😅

#

I haven't calibrated linear advance! Didn't think of that

Thats fair...
But is linear advance different to pressure advance?

linear advance is marlin's pressure advance

pa pattern is easier to understand

Ok, I'll try lowering PA a bit.
It's actually quite hard to tune PA using Orca's provided tower model.

what pa value did you use

outer meadow what pa value did you use

From 0.24 to 0.4 iirc

outer meadow Jan 25, 2025, 5:14 AM

#

pa usually has a value more like 0.02-0.08

magic flower Jan 25, 2025, 5:15 AM

#

Or was it 0.024~0.04?

hopefully

I think it is. I don't have much issue printing regular things

#

I struggle with small and thin prints like these though
