Can't get consistent results on UM2+ since purchasing.

Posted · Can't get consistent results on UM2+ since purchasing.

Hey All!

 

I've been struggling to get consistent results on my UM2+ since purchasing.

 

Elephants foot always seems to be present, even when all initial layer settings are set to 100%...

 

The various lines which appear to be present on almost all perimeters is particularly frustrating..

 

Attached are some pics of the printed part, as well as the Cura Project file. (3MF)

 

If anyone has any ideas, I'd love to hear them.

 

thanks in advance.

To battle the elephant feet you could look at the initial layer horizontal expansion setting in Cura. 

 

For the layers you might want to look at the acceleration / jerk settings in speed and perhaps print a little bit slower in general. More info can be found here: https://support.ultimaker.com/hc/en-us/articles/360012611079-Speed-settings

 

Hope this helps!

Hi netminder,

 

Just looked at your print project as I've also have an UM2.

If I'd read your project file right, you're printing with a 0.6 mm nozzle and speed  at 60 mm/s?

Right?  If so, this is way to fast for such a nozzle with such a detailed object I'll say.

Also the flow request for this is very high.

In order to print all this details you should use a 0.4 mm nozzle, a much better match for your print.

Your printer can print this object very well.

For Cura 4.6.1, use default fine, select your infill and select skirt. Reducing "print speed" is very effective in order to avoid issues in the object (resonance/shadows etc.).

This should work well for your printer.

(Actually I'll think your printer worked very good in spite of this to high demand 🙂).

When it come to elephant feet, it is much better to have those -than a print come loose from the bed, oh yes, tried that..

 

Some use to reduce first layer in the original 3d drawing in order to reduce this effect.

 

Hope this help

 

Good luck

 

Torgeir
