I need help. I just started printing this part with Petg. Its orange with black letters. When it changes color its bleeding the black into the orange. Ive tried turning my purge up to the maximum 800 and it didnt help. Tried turning wiping on at 2mm with a z hop and the bleeding persist. Im ising a priming tower. What am i missing. Extruder temp is 255 ned is 70 on a P1S. Do i need to extend the wipe?
Have you looked at the flushing volumes?

The other important thing is the order the colours print. Ideally, lighter first working to darkest.
- Locate the cog hex icon on the right of the build plate.
- Select it
- Locate the two colour sequence settings and change them.
- Drag the lightest colour to the first spot and work your way through. Unfortunately, the drag and drop is actually drag and swap for dumb reason.
Make sure first layer and subsequent layers are set.
This reduces the potential for bleeding and there isn’t such a big swap between colours, when there are only two, the logic is the dark isn’t first so it will not be spread during light areas being printed.
A test with colour sequence might be your best bet, only print a few layers to tell. Remember, you can lower the model below the build plate to get at the affected area immediately.

I did adjust the flush volume all the way to its maximum of 800mm. It didnt stop the bleeding.
Make sure to turn off “Flush into objects’ infill” this can help. Also look at the size of your prime tower. I usually run mine very small (15mmx15mm) but sometimes I notice color bleed when doing this. Try a standard size or larger as a test. Last option is your infill density. Not sure how much help it could offer but a few %increase could give more surface to flush the color. Maybe…
