[BUG REPORT] Vertical Blob lines

PostbyBigE79»Thu Dec 13, 2018 3:56 am

When printing large diameter circular parts I'm noticing a vertical line of blobbing. The photo below shows the blob line on the outside of a part but I've seen this in other parts too.

This part is hollow and the same line is on the inside too. As you can see it's also not consistently on every layer but is on most layers.
The blob sticks out 0.6 to 0.8mm from where the surface should be.

I've only noticed this on 0.2mm layer height using ABS+, I've not noticed it on 0.1mm before. I'm using just normal print setting on raft on the perf board.
I assume this line is where the layer starts and/or finishes but I'm not sure. Could there be some over extrusion here?
Is there any way to prevent this?

That doesn't look right - I get similar lines on some of my models too, but nothing that severe - I work mostly in ABS too, at 0.1 and 0.2

When I do see something like that, it's always ( so far ) support structure and picks off easily...

I've never seen it bulge like that - What are your other settings ( speed, etc ) - Send the model too if you like and I'll try printing it and see if I can recreate it.

Hi David,

I've done allot of printing but usually in 0.1mm not 0.2mm and not seen this issue until recently.
Note: This is in ABS+ not ABS but I don't know if the material difference has as any effect. My settings are all the default setting on ABS+ except I'm using stable supports. That model however only requires one small support in the center.
Setting are below:

I've attached the file if you can try it it would be greatly appreciated. Then I'll know if it's a hardware issue or slicing.

Cheers,
Erik

Okay is seems these posts get confused if you try to attach more than one file. Works in the preview but then it gets confused.
I'll try again with the settings:
