Rough surface and ocasional hole in the print

[iDig3Dprinting]

The gaps in the printing may also be due to poor filament quality, either too much moisture or some form of contamination. Poor quality filament results in inconsistent extrusion.

This article on problems with poor quality printer filament may be of some interest.

Ok after some fiddling with temperatures and speed, i got rid of the gaps, but the "bumps" are still there and the surface is still rough. There is actually no change in the roughnes and bumpyness of the surface at all, no matter how i change the settings.



I think ill buy lot of sandpaper. :-)

Can you change your prime/unprime settings? Retract more and advance less between printing and non-printing moves.

[Mirek]

Ill try, thank you.

one thing that seesm to have slipped by these guys.

You say it lifts the print head when it retracts.
That's make bumps.
Plus it's totally unnecessary.
Set that to 0.
The less stop and start movement the print head makes the smoother the final print.

So retraction, yes, head lift with retraction, oh hell no !

try that.

And what slicer are you using ?

Slicer? (10chars)

[iDig3Dprinting]

Slicer, the software used to convert a 3D model file into G-code, the computer code used to control the actions of your 3D printer. You can also use it to change settings on your print. see our brief guide to 3D printing software.

I use the software that came with the printer. Its called G3DMaker.
