[Print quality problem]

Hey sorry for the delay, things have been a bit hectic with the build up to christmas so I havent had much time to run any prints.

The good news is I did manage to get a new nozzle and there is a definite improvement as shown in the link below.

(All settings the same as in the initial post)

http://umforum.ultimaker.com/index.php?/gallery/album/385-printing-issues-3/

Left hand print is with the old nozzle at 100% speed (Ultimaker settings)

Middle print is with the new nozzle at 100% speed

Right print is with the new nozzle at 80% speed

There is obviously still some fine tuning to do but still a big improvement.

Gr5 - Thats the actual nozzle I received with my ulimaker, im not quite sure what happened to it!

How often would you expect to replace a nozzle?

Illuminarti - Could you send me more info on parts you are able to supply please. I would be interested to take a look.

Valcrow - Thanks for your help. Your prints are looking great.

Good evening guys, thanks for the rapid response.

I tried a few test prints last night following your advice (Results posted on the link below)

http://umforum.ultimaker.com/index.php?/gallery/album/347-printing-issues-2/

Cura settings as laid out in my original post.

Left hand print is 50% Speed (Set on ultimaker), Hot end 210, feed 100

Middle print is 50% Speed (Set on ultimaker), Hot end 210, feed 120

Right print is 50% Speed (Set on ultimaker), Hot end 210, feed 130

Illuminarti - As you can see there was a definite improvement with speed reduction. I did do a print at 60% speed but results were better working at 50%. Tomorrow I will try dropping the speed even lower. However it does seem to be very extreme to print at such a slow speed. These prints all took 65 minutes each. The fan seems to be working correctly though and minimal layer time is set to 5.

Gr5 - I cant see any obvious problems with the nozzle (See picture link above) but I will order a new one to be on the safe side. The nozzle could be at least part of the problem as the print always has the most issues at the back on the left hand side. This can sometimes be kept to a minimum by increasing the feed rate as you can see.

Will try the water test tomorrow and let you know the results

Big thanks to both of you, I will look forward to reading your response.

Hello to all,

 

I have had my Ultimaker 1 for about 6 months but for the last 3 months the print quality seems to have dropped damaticaly.

Here are a few pics to help me explain the problem

http://umforum.ultimaker.com/index.php?/gallery/album/345-print-issues/

The first pic is of the Cura settings I am using. Although when I print I usually change the speed settings to 80 manualy on the actual printer controller.

The first yellow robot is the factory printed robot that came ready printed on my ultimaker.

The purple robot in the middle is printed with standard settings as explained above

The purple robot on the right is printed with the same settings but with the feed turned up to 150. This results in a very slight improvement but a loss of detail in other areas.

Also, for some reason no matter where i print the model on the plate the print quality seems to be worse at the back of the model. Very weird!

Any suggestions would be much appreciated

Luxy
