Raised Edges - Simple Metal

Recommended Posts

Hi guys,

I have started to use Cura and all my prints are almost perfect except one problem.

I have found same issue on this forum but couldn't fix it on my Printrbot Simple metal

I basically have raised edges, it looks like over extruded, but I have reduced filament flow and still have the problem.

But what interesting if I print a cube it happens only on two corners . please see image.

Thanks for your advice.

Thank for your guys.

Yes, I have tried to print more then one cube, with and without brim.

Both cubes have the same issue and only from one side!

I have tried to rotate them the issue still from the same side.

It looks like it is a point where hot end stops and starts to print next layer.

 

What does Z- seam means and how to fix it?

 

Cheers

Ok...

I have just printed some tests.

Settings are the same

1. Two cubes with option print all at once. And they are perfect!!!

2. Just a single cylinder. It has two seams

3. One cube - seams on two corners again

There should be a solution, I can't print all parts two times ))

Just a thought maybe it it because of Z-Hop. Mine is 0.075

 

Hmmm... that's maybe a value the printer is not comfortable with. Try 0.1mm as this is the z resolution of the Simple Metal, isn't it?

What print speed do you use? A lower print speed might smooth the effect as it doesn't have to slow down that much for the z step... Can you reduce the temperature a bit without getting underextrusion or are you already at the lower limit?

Hi there,

Yep i will try with 0.1. Thanks for suggesting this.

I am printing at 195 -197C and my printing speed is 50.

I can try to lower the speed to 30 and temperature to 190C - just to test.

Will come back with resultsrobably tomorrow

Have you got one or two extruders? I ask because I can suffer from this on the cube too and I have two extruders, which pushes the right hand fan further away; this makes me think the right hand side is not cooled enough. I am thinking that your success with printing two pieces might support that view.
