How to improve this print..

Recommended Posts

Hello Folks

i have finally gotten my printer alive with some decent prints.

Can you guys help me to figure out what i could adjust to get some smoother prints?

My printer is an ultimaker 1 with some modifications, and im printing PLA.

Here's a link where ill upload my pictures from my phone:


The problems can be from the printers mechanical side, and if it is then it would be great to know what to change to make it even better :)

Both my profile from cura is in the folder and the gcode for the file.

i really hope some of you can help me out.

Hi Thomas !

what speed and temp did you print ?

do you have any type of belt tighteners ? that really does help reduce spring in the movement and give cleaner surfaces.

Also a little dribble of fine machine oil on the axis really helps...

Looks like things are getting good for you !

Have great fun with your ultimaker and ask us anything you want !

Ian :-)

Hello Ian

my speed is 50mm/s and 220 degrees hotend and 55 degrees heatedbed + fan always on.

i got belt tensioner on both axis. i have been looking for some good machine oil but that made it alittle worse (harder to move the print head).

and also the layer height is 0.12mm.

Im glad you can see im getting something out of my printer because im getting frustrated :b

And thanks :D

make sure the axis are really firmly pushed into the blocks... sometimes they arent and then the squareness of your axis can be a little off and cause friction.....

your settings sound good to me... your using Cura right ?

I dont really understand why the oil would make things worse... I mean make sure you only have the heavy green oil on the back spine and then clean the other axis with a clean piece of cloth.. then a little oil and move around the head with your hand until things soften up...... should work...

you know the little wooden blocks that hold in the metal axis... they are quite delicate and can be easily bent and broken and if there is some play or the axis is simply not slotted in fully... then that can cause problems...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
