Cura 2.1.2 - Z Seam "blob"

Recommended Posts

Ladies and gents,

Question about Cura 2.1.2 and Z Seam - on some of the prints it looks like a thick blobby line.

For example calibration cube, one corner is complete blob all the way up.

I'm pretty certain that this wasn't happening on older versions of Cura and I'm certain that it's not a printer thing either because it works fine with Simplify 3D.

Same STL - 2x completely different results.

Am I missing something what I need to tweak?!

Thanks.

Regards,

Kris M

@DaHai8 - Thanks for the reply.

My Cura settings are pretty much unchanged apart from temp, supports and infill.

I've tried to disable Combing - still the same.

Tried to increase and decrease retraction mm and speed - still the same.

By now I think I've tried to change all possible settings in Cura just out of desperation but still the same thick corner in cube's case or just thick Z seam on any another print.

I found something.

Loaded both gcode's into Repeater-Host to see where is the difference.

If you look at the Z Seam on both you can see that Slicer leaves little gap in between but Cura doesn't.

Is there somewhere in Cura I can define that?!

Check for combing. Combing deactivates the extruder at the end of a loop so there's less pressure when it goes back after a retraction. Also, it should help with that.

On S3D I use mostly wipe+retract to have a better control of the blops, but for some materials I need combing so there's less pressure + less dripping when moving from point a to b, and more blob control.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
