<![CDATA[SoliForum - 3D Printing Community — Random blobs]]> 2017-06-05T02:42:35Z PunBB https://www.soliforum.com/topic/16241/random-blobs/ <![CDATA[Re: Random blobs]]> So I think I found the problem on accident. I couldn't figure out why this issue was across all my printers. Its actually quite simple, the common denominator was all my printers are connected over usb and I get these random pauses almost like communication drops. Switched over to sd card and no more pauses. The only other thing I'm seeing is that I have excessive retraction forv some reason.

- Move Z at the fastest velocity, acceleration and jerk your set up will reliably allow.
- Play with jerk and acceleration on XY. Your machine may be configured to the default which is 1500 or so acceleration and 20 jerk which can be increased.
- Do not force retractions on layer changes. Cura likely has a setting for this somewhere.
- Retract as little as you can, speed is not as important as distance. You can also play with E acceleration and jerk to increase retraction speed, but on a direct drive extruder set up like the Solidoodle retractions are fast anyway.
- Use a wipe function if Cura supports this.
- Fast travel movements, 100mm/s+

You will never eliminate a seam but you can reduce their ugliness.

if you are getting seams in vase mode you have other issues.

I have z hop on I believe but it's .2.  I know I can't get rid of the seam completely but I believe there is a way to reduce the amount of Filament deposited so it won't be as large.

But I also noticed with Cura, no matter how many settings I changed, even running in Spiral Vase Mode, I couldn't get rid of the seam. Have you tried running the same print with slic3r or s3d?

I just did a vase and noticed something quite interesting. Those bumps correlate with the layer change as I have a huge seam with no bumps and where there is no seam a small bump. The question now is reducing the seam or left filament.

http://www.instructables.com/id/DIY-3D- … nt-Dryer//

Should function similar to the print-dry without having to buy another dehydrator.

Will post results once the container arrives tomorrow.

One thing I can't seem to figure out are these random blobs. I thought maybe retraction but its running in single vase mode. The hot end is a e3dv5 .4 nozzle
Petg black at 239 temp 60 bed

The printer is not running fast at about 45 print speed
And 38 perimeter using cura.
