Re: Tweaking the blobs out
How many print hours since the last coupler was replaced?

Re: Tweaking the blobs out
In my case that was no problem, as the brass was touching the nozzle anyway

Re: Tweaking the blobs out
The only tinkering that might be required is the fanshroud. My old designed fan shroud was too large, the nozzle didn't clear the shroud as the Ruby is less high than the original UMO nozzle. Do you have a picture of your hot end? And as Neotko mentioned, your coupler?

Re: Tweaking the blobs out
I do, buried in the ruby nozzle test pilot's thread
So if the nozzle sits flush on the heater block, that's no big deal? I thought it was.
When I first mounted the nozzle post
Then installed
I'll have to dig through the Shroud thread to see how it worked with the dual fan cap

Yes, it does fit. Found a few pics....I had used the ruby a lot for many prints and that shroud.

Re: Tweaking the blobs out
Finally a night to assemble a ruby nozzle and install it in the UMO. I had to raise the Z limit switch a half inch so the nozzle got close to the bed. (Forgot I had to do that last time too). The nozzle sticks out a good deal since the brass pipe is in so far but I heated , tightened and checked again. Everything seems flush
Here's that robot print with the ruby

Re: Tweaking the blobs out
That looks a lot better or not? Strange right?

Re: Tweaking the blobs out
He looks a bit better, if you click on the image, there's still a few blobs by the left eye
This is using Ultimaker silver PLA, so it may desire a higher temp. I printed at 215C, which is what my Colorfabb materials like with the ruby nozzle.
Tonight I'll try it again at 225 and see what we get.

Re: Tweaking the blobs out
Here's 230C
I wonder if I should increase the fan a little?

Re: Tweaking the blobs out
Still the same blobs. Hmm. Not sure what else to tweak on this. Maybe a bit more retraction? Using the latest Cura

0.2Izzy wrote: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.
Ruby nozzle 60C bed, 40 mm/sec
Looking at retraction it is 45 mm/sec and 4.8 distance, which I can increase
Did a few searches and Minimal Extrusion setting might be worth looking at

Re: Tweaking the blobs out
Just tried a little experiment
Ever tweak so much in Cura you suspect one of the zillion of settings is fouled up? Yeah...so went to 15.04.6 which has always worked fine. I don't dare touch 2.3.1 since I have nGen setup darn-near-perfect for the Ultimaker 2+ (I really wish I could saving settings and name it 'nGen' and make something similar for Colorfab PLA, for Ultimaker PLA, etc.)
With that said, I did the robot with the same basic settings... 0.2 layers, 225C , bed at 60C, retraction at 45 mm/sec and 4.6mm distance....and it came out very nice! I decided to do a different print, this time the 2 owls one. Again, same settings but a tad more fan since we still have a little droop in the Ultimaker robot's chest. 3 hours to go!

Re: Tweaking the blobs out
Re saving your profiles,
you can with S3D and I thought you could with Cura too, I haven't used it for a few months now but I'm sure you could save profiles.
