Hi everybody,

 

And again...thanks for your answers !

Here are some pictures of my "problem"

My 3D model is 50x50x10mm (x/y/z)

I guess I have enough edges

@yellowshark >> yes I am taking mesurement at different height of the circle (top, bottom and middle)

I am using a sliding digital caliper. I know it is not that precise, but I think its enough to notice that my circle is not round (pictures enclosed)

The tension of all the belts has been done as well as the X and Y axes alignment.

All the pulleys are clean and tighten

I print PLA (205°C) with a bed at 40°C 

The nozzle is a 0.4mm

Layer height is 0.1mm

Speed is 40mm/s 

I did print another one at 30mm/s...it is a bit better but not as good as it should be, I still avec an average of 0.25mm error and the diameter

 

Thanks

Hi gr5,

 

Thanks for the answer, it make sense !

I print PLA so my bed is at 40°C (nozzle 205°C) but my printed circle is only 10mm high (Z) so I will have a try tomorow with a higher one and I will let you know (with pictures).

To be a bit more precise, all the diameter variations are mesured at the same height, so technically speaking my circle is not perfectly round at a determinate height.

 

Thanks

Hi, 

Thank you for your answer. It is really helpful.

But when I talk about "variation of the diameter of 0.3mm" I mean that the diamater for my 55mm circle varies from 54.89mm to 55.18mm

Thanks

Hi, 

I would like to know what are the printed conditions and best parameters to obtain the maximum accuracy on a Ultimaker 2+ ? As decribe on the specification sheet of the Ultimaker 2+ 

For exemple I am printing a simple circle/disk that is suppose to be 55mm diameter (PLA / layers 0.1mm / speed 30mm/s) but when I mesure it after it has been being printed I obtain an average variation of the diameter of 0.3mm.

The tension of all the belts has been done as well as the X and Y axes alignment.

All the pulleys are clean and tighten

 

Thanks in advance for your help  and advice
