Tweaking the blobs out
Ultimaker Silver PLA
210, 220, 225. Maybe more fan at 225?

Re: Tweaking the blobs out
Try 230'C just to see if it is to high

Re: Tweaking the blobs out
I think I will up the retracting distance from 4.6 to 4.8 and see how that goes too

Re: Tweaking the blobs out
For me this was solved using Ruby nozzle a dual fan(can't tell which did the trick as both were installed at the same time)

Re: Tweaking the blobs out
Well the printer has the dual fan. Ultimaker PLA is a much different creature than the ColorFabb I have used almost exclusively in the past

Re: Tweaking the blobs out
The Ultimaker filament was ok at a push, but not as good as ColorFabb or Faberdashery PLAs

Re: Tweaking the blobs out
I'm just trying to figure out how to make a decent print with it!

Re: Tweaking the blobs out
I have a little bit of Colorfabb Dutch Orange and thought I'd print robots in each filament and see if both get blobs. Both do
I even checked the extruder Hobbes piece. It was clean but sometimes I notice nothing moves when I manually crank. Should I adjust that bolt tighter on the U-bracket/clamp piece?

Re: Tweaking the blobs out
I wonder how long the hobbed bolt lasts...is it time for a new one?

Re: Tweaking the blobs out
Well I can see the filament moving in and out of that extruder drive very nicely. I removed the filament and took a small brush to the surface while slowly rotating it. No debris, so it isn't dirty.
I'm truly stumped! What's causing the blobs!

Re: Tweaking the blobs out
Are you running a Ruby Nozzle in the UMO?

Re: Tweaking the blobs out
No, the standard brass one. I've done atomics and it's clean.

Re: Tweaking the blobs out
Two questions, what layer height are you using?
The photos attached are at 0.1mm (100um) layer heights. 210'C Nozzle,50'C bed at 45mm/s.
Material is Ultimaker PLA red.
And what are you using to photograph with, good quality images

Re: Tweaking the blobs out
Paul, you are sitting on a stash of Ruby Nozzles right. So I'd say pop one in(or pop one in that comes from your UM2+), and see if that helps
You remember that geared heart topic I had? Loads of blobs everywhere. After installing dual fan and Rubby Nozzle it was gone 100%. Same filament, same settings(albeit a little hotter to compensate for the ruby nozzle).
Since you already have the dual fan, the ruby nozzle is my only idea

Re: Tweaking the blobs out
My only concern putting the ruby in is I have to mess with the brass pipe fitting into the heater block. As I recall, just removing the original nozzle with the ruby leaves it sitting flush with the heater block.
