Retraction settings? What do I change in slicer to get rid of these marks? Did not get them on any model before I changed filament type
Best Answer by bobstro:
Those are likely at least partially due to the z-seam placement. You can move it around, but it has to go somewhere. Usually hiding it in a corner helps. Try changing Print Settings->Layers and perimeters->Advanced->Seam position. If you change that setting, the blemish will move around. I suspect you have it set to "nearest" which will put it in a corner that can vary by layer. Try aligned or rear and it will put the seam all in the same corner or at the rear of the print. You'll have to decide which is the least disruptive.
Other than that, you can mitigate the seam appearance. First of all, try simply slowing down and see if it has an impact. Calibrating your filament extrusion multiplier can also help. Some relevant notes here.

Which filament is this?
How many perimeters are you printing?
Cheerio,

It's FilamentPM with 2 perimeters(Vertical shells).
Everything should be default, only used prusament so far. Same model is perfect with the filament I got with the printer.

Ok, thanks. I will try moving it and see if it's enough.

Moved it to rear, seems to work fine. Only wonder why this has not been an issue when I used the filament I got with the printer, or any other prusament i've used? First time I see this now when I changed to FilamentPM. (Someone told me they make the grey filament prusa sends out with new printers).

Most of the defects that we worry about are variations of a fraction of a millimeter. It only takes a slight variation to mar what is otherwise a smooth -- or at least consistent -- surface. If your filament varies from one brand to another and if you haven't calibrated or used a calibrated profile to account for variations, you'll get differences between filaments. Even with prepared profiles, I still find it worthwhile doing a bit of calibration for each brand and type of filament to adjust the extrusion multiplier and diameter settings in the slicer to make sure it's consistent on my printer. A lot will also depend on the print, and what opportunities the slicer has to hide the seam elsewhere. It sounds like your corners got better when you moved the seam to the rear.

Understand, yeah they did. Can still see them but back better than aligned. Aligned looked perfect but almost at the top the seem came out on the front corner again. Will look into extrusion multiplier and diameter settings, thanks.
