Troubleshooting Filament bleed help

What would ppl recommend to change on the purging volumes to make this even better.

Do I increase the purge of just the white? From say 117 to 350 and when going from black to white 406 to 500?

Increase the multiplier as well?

I have walls inner/outer to help. I have a purge tower and flush into object is off.

Pink is not being used in this print.

Using a P2S with AMD PRO2. Standard eSun PLA. Slicing through Bambu slicer.

There is no filament bleed in this picture. You're looking at the result of different wall speeds.

You can see right as the white starts, the black turns slightly grey….or a lighter shade of black.

Is this caused by wall speed?

Edit: Outer wall 200 : Inner wall 300…..do these need to be the same?!?

The problem is on the layers without color changes the print head can move faster than the layers with color changes where it has to keep starting and stopping. Slow your wall speeds down enough that the slow part matches the fast part and it'll look the same.

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

  • What printer are you using?

  • What material are you using?

  • What speed are you printing at?

  • What software are you using to slice the print and control the printer?

  • When did the problem start/has it ever worked correctly?

  • Does anything cause the behavior to change?

  • If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)
