First Prints

Recommended Posts

I've finally put my hand on my brand new ultimaker 2... and now i'm printing like hell!

But there are some strange behaviors that i need to understand.

The Material Feeder sometimes seems to lose the grip or to be stuck and go back quickly... it sounds like a strange thing.. i will post a video.

Here:

 

P.S. how can i adjust the build plate screw?? which one and where? In the manual there is no such an image to understand it!

The extra fast "click" where it goes backwards suddenly (but not then forwards the same amount) is when the stepper motor doesn't have enough power and it slips. If you are getting a few clicks occasionally it should be fine but if you are getting them this often then you have too much pressure in your nozzle and you will get underextrusion. You can ignore this but if you want beautiful prints you need to either raise the temperature (make the PLA more like honey and less like toothpaste) or slow down the print speed (to give more time to get all that plastic through the tiny nozzle.

So either slow down your print, or print with thinner layers (less plastic) or raise the temperature. Or if the quality is good enough don't worry about it.

If it does the click often on the *first* layer it's not a problem. It may mean the bed is slightly too high. But if it does it on the other layers it means you are underextruding.

Cut your speed in half and it will click less. Keep cutting the speed in half and eventually it will stop clicking. Here are tests I did. I found that my max speed at 210C .2mm layers (for ultimaker blue filament) was around 40mm/sec. Of course with .1mm layers you should be able to go twice as fast.
