Bad print quality with 0.3 nozzle


#1

Hi everyones, I tried to get a better prints quality on thin walls by setting 0.3 nozzle on my M200+ (with the latest firmware, and latest Z-suite versions) and as you can see on my picture, the result is disappointing…

I have used the same settings for the 0.3 and 0.4 nozzles, instead off setting 0.3/0.4 nozzle on the specifications…
That is to say for the 0.4 nozzle:

Estimated print time: 0h 57m
Material usage: 2.64m (6g)
Printer: Zortrax M200 Plus
Profile: Derniers paramètres
Support type: Automatique
Support: 0°
Material: Z-ULTRAT
Nozzle diameter: 0.4 mm
Layer: 0.09 mm
Quality: High
Infill: Solide
Fan speed: 100%
Seam: Régulièrement
Outer contours: 0.00
Holes: 0.00
Surface layers Top: 9
Surface layers Bottom: 4
Support Lite: Oui
Smart bridges: Oui
First layer Density: 100%
First layer Print speed: 100%
First layer Flow ratio: 100%
First layer gap: 0.23 mm
Raft Enabled: Oui
Raft layers: 6
Platform-raft gap: 0.20 mm
Raft Density: 100%
Raft Print speed: 100%
Raft Flow ratio: 100%

and for the 0.3 nozzle :

Estimated print time: 1h 56m
Material usage: 2.76m (7g)
Printer: Zortrax M200 Plus
Profile: Derniers paramètres
Support type: Automatic
Support: 0°
Material: Z-ULTRAT
Nozzle diameter: 0.3 mm
Layer: 0.09 mm
Quality: High
Infill: Solid
Fan speed: 100%
Seam: Normal
Outer contours: 0.00
Holes: 0.00
Surface layers Top: 9
Surface layers Bottom: 5
Support Lite: Yes
Smart bridges: Yes
First layer Density: 100%
First layer Print speed: 100%
First layer Flow ratio: 100%
First layer gap: 0.19 mm
Raft Enabled: Yes
Raft layers: 7
Platform-raft gap: 0.22 mm
Raft Density: 100%
Raft Print speed: 100%
Raft Flow ratio: 100%

So is someone can help me to hunderstand why the thick walls, witch are 0.85mm thick, are better with the 0.4 nozzle, and disgusting with the 0.3 nozzle … and the thin walls, that are 0.55mm are well in both case…
By the way, I notice that the printer is very fast to make the thick wall, then I guess that this fast make the printer vibrating and loose maybe in accuracy…
And I have check the plateform calibration…

Thank you in advance, and sorry for my bad english

Hi Marta,

Thank you for your answer.
How can I send it to you in private ? Because it is quiet a bit a sensible project…
By the way, I forgot to specify yhat I have the Zortrax cover on top with the fan top speed setting on.

And in wayting I succeed to manage to have a nice print by reducing the wall thickness, but this should be good for this project, but it dosen’t fix the trouble that it dosen’t print properly with the first design.

Thank you again

Flo
