Topic: Cura III / slicer? questions

I've been using the Cura that came with my Monoprice Ultimkaker. 

I've noticed that sometimes the way it decides to start and stop a layer in the same place for each layer causes weird artifacts.  If I could choose where the start & end points are I could improve the finish of a part.  Sometimes, randomizing them might be better, sometimes just choosing the right place where the artifact won't matter would be better.

I often print many identical small parts in one batch / one gcode file. 

What are option / where do I find out about this sort of thing?

Re: Cura III / slicer? questions

If the joint is that pronounced then you could be over extruding or under extruding. But there is a setting in most slicers to randomize start point. That is the best way to avoid the issue if you can't get your extrusion rate calibrated properly.

I'll have to look for that setting.  I have adjusted the extrusion and retraction a fair amount, to get the overall finish optimized.

Have you actually calibrated your extrusion so that you print a single wall at .48mm thickness?

Re: Cura III / slicer? questions

I have not heard of this before....

Is there a link somewhere to the procedure?

When I installed the Bondtech  feeder, I had to re tune the extrusion.  It started off too heavy, so I dialed it back a few % and ran a build.  Repeated this a few cycles until it started to look under extruded, and settled on the setting I have now.

Re: Cura III / slicer? questions

I personally use Slic3r, but the procedure should be basically the same...

any questions, just ask...

and for the record.. 90% of what those two links talk about has been gleaned from multiple posts & people right here in this forum. All I did was gather it all up and put it all in one place in (i hope) a fairly easy to follow guide
