Dual extrusion advise. Issue in layers where dual color is happening

Hello

I need your advise. I am trying to print dual color. There is an issue only on the layers that dual color is printed,

Slicer:Orca basic settings. I will try to include the GCODE

Printing seperately with each nozzle works fine. The issue is only happening when printing dual colored.

Material is PLA.

I’m having the exact same issue. I can create a print with either the left or right extruder, but when I try to print a two-color print, I get the same result on layers where both extruders are used. As I see in your photo, when a layer uses a single extruder things seem to go back to normal. Did you get a fix for the issue? I was wondering if it had to do with heat up time on the extruders as they change in a layer. I’ve tried a lot of adjustments but no luck so far. LMK if you found the problem.

No I do not have any solution. I just gave up on it. Using my Palette 2 instead for 2 color prints.

The photo is not good.

If I guess correctly that the tool changes are at the bad surface, it’s something with xyz offsets.

I bet the z- calibration between the two nozzles is not correct.

This would be great to see if you observe the print.
