Top surface irregularities

[laurent-rodriguez 0]

Hi,

When printing the top surface, the print head doesn't move continuously from point A to point B but fill the the top surface by "zone" and it generates irregularities when joining those zones. You can see the difference from the first picture that is printed with another slicer engine and the other picture printed with Cura. On the part printed with Cura the top surface is divided by printing zone.

Is there a way to avoid that?

Thanks a lot for your help

No but you can improve the surface quality by unchecking "combing" feature and having the Z move up on travel on surface to eliminate scarring caused by hot nozzle moving across the surface. There is a really nice plugin for this - hopefully someone will post about it as I haven't used the plugin.

Alright, I'll try unchecking combing first and see if lifting Z for travels is necessary or not. I'll let you know about my results.

Thanks gr5

The Plugin is called Retract while combing. Very nice Plugin. The scratches are totally gone with this Plugin.

It's hard to see from your photos, but you might have backlash issues. Are all your belts tight and pulleys fully secured?
